Frequently Asked Questions
Choosing the Right Type of Contact Lenses
What are the differences between soft and rigid contact lenses, and who are they suitable for?

  • Soft Contact Lenses
    Made from hydrophilic materials such as hydrogel or silicone hydrogel, soft contact lenses are flexible and conform closely to the surface of the eye. They offer minimal initial discomfort and are easy to adapt to. However, their oxygen permeability is relatively limited, and prolonged wear may lead to corneal hypoxia, causing issues such as corneal swelling or neovascularization. Soft lenses are ideal for beginners, occasional wearers, individuals with sensitive eyes, and those who prioritize comfort.

  • Rigid Contact Lenses (RGP)
    Rigid Gas Permeable (RGP) lenses are made from breathable, rigid materials. They provide more precise vision correction, particularly for astigmatism, and have high oxygen permeability. These lenses are also less likely to accumulate protein deposits, helping to maintain lens cleanliness and support corneal health. However, they can cause significant initial discomfort and require a longer adjustment period. RGP lenses are suitable for individuals seeking superior vision correction, those with high levels of corneal astigmatism, keratoconus patients, or people who need prolonged clear vision, such as athletes or pilots.

What are the differences between daily, monthly, and yearly disposable contact lenses?

  • Material:

    • Daily Lenses: Made from high-water-content, thin, and soft hydrogel materials to ensure comfort for short-term wear.
    • Monthly Lenses: Share similar materials that balance softness with durability. As the replacement cycle lengthens, the material’s stability improves.
    • Yearly Lenses: Designed for long-term use, these lenses are relatively thicker and harder, with greater resistance to deformation.

  • Oxygen Permeability:

    • Daily Lenses: Provide better oxygen permeability to meet the needs of short-term wear without frequent removal.
    • Longer Replacement Cycles: As the usage cycle extends, protein and lipid deposits accumulate on the lens, reducing oxygen permeability. Annual lenses, in particular, tend to have lower oxygen permeability.

  • Cost-Effectiveness:

    • Daily Lenses: Have a higher per-unit cost but eliminate the need for additional care products, resulting in higher overall annual expenses.
    • Monthly Lenses: Offer a moderate balance of cost and convenience.
    • Yearly Lenses: Feature lower per-unit costs but require ongoing investment in cleaning solutions, lens cases, and other care products.

  • Selection Recommendations:

    • Daily Lenses: Ideal for individuals who travel frequently, have irregular schedules, or lack strict hygiene habits, as they are convenient and require no maintenance.
    • Monthly Lenses: Suitable for those with a regular lifestyle, moderate eye usage, and a focus on cost-effectiveness.
    • Yearly Lenses: Best for those who wear lenses consistently, have good eye tolerance, and seek economical options. However, strict adherence to cleaning and care routines is essential.
Which Type of Contact Lenses Provide Better Correction for Astigmatism? Is Customization Necessary?

  • Rigid Contact Lenses (RGP):
    Rigid gas-permeable lenses offer excellent astigmatism correction. Their firm material creates a stable tear lens on the corneal surface, precisely correcting astigmatism at different axes.

  • Soft Contact Lenses:
    Specially designed toric lenses for astigmatism incorporate unique curvatures and varying refractive powers across different directions, allowing for effective astigmatism correction.

  • Recommendations Based on Astigmatism Degree:

    • Mild Astigmatism (Below 50 Degrees): Regular soft contact lenses are usually sufficient for correction.
    • Moderate Astigmatism (50–150 Degrees): Toric soft lenses or well-fitted rigid contact lenses are good options.
    • Severe Astigmatism (Above 150 Degrees): Rigid lenses or custom-made high-astigmatism toric soft lenses offer better correction. These typically require customization by an optometrist based on individual eye parameters.
How to Determine Whether to Choose Regular Contact Lenses or Colored Contact Lenses (Circle Lenses)?

  • Vision Needs:
    If your primary goal is vision correction, regular contact lenses provide stable optical performance and precise correction for all prescription levels. However, if you want to change your eye color or enhance the appearance of your eyes, colored contact lenses are a great option. Keep in mind that the pigment layer in colored lenses may slightly affect visual clarity, so individuals with high myopia or astigmatism should choose carefully.

  • Aesthetic Preferences:
    If you want to enhance your daily makeup or create versatile looks, colored contact lenses can complement your skin tone and suit different occasions, making your eyes appear more vibrant and captivating. On the other hand, if your work environment or personal preference leans toward simplicity and a natural look, regular contact lenses preserve your natural eye color and maintain a more understated and professional appearance.

  • Eye Health:
    For individuals with sensitive eyes, frequent dryness, or a history of eye inflammation, regular contact lenses are generally a safer option. Their simpler materials lower the risk of allergic reactions or other adverse effects. Colored contact lenses, due to their pigment layer, may increase the likelihood of eye irritation or allergies. If you choose colored lenses, ensure you select high-quality, breathable options and strictly adhere to proper wearing and care instructions.

Choosing the Right Contact Lens Size
What is the Base Curve (BC) of Contact Lenses
Definition of Base Curve (BC): The base curve refers to the curvature of the inside surface of a contact lens, which needs to match the curvature of your cornea to ensure a proper fit. It is typically measured in millimeters.
How to Measure Your Base Curve?
  • Professional Measurement: You can have your base curve accurately measured at an eye clinic or hospital using a corneal topographer or keratometer, which are specialized devices for assessing corneal curvature.
  • Advanced Tools: Some modern eye-scanning devices can also quickly provide your base curve measurement.
  • Online Estimations: Certain online fitting tools or retailers may estimate your base curve based on factors such as your eyeglass prescription and age. However, these methods are less precise than professional measurements.
What Happens if the Base Curve is Incorrect?
  • If the BC is too large:
    • The lens may fit too loosely, leading to poor adherence to the corneal surface.
    • This can result in lens movement or slipping, causing blurred vision and a strong foreign body sensation.
  • If the BC is too small:
    • The lens might press too tightly on the cornea, restricting oxygen flow to the eye.
    • This can cause issues like corneal hypoxia, swelling, pain, redness, and, over time, may harm corneal health.
  • Ensuring the correct base curve is vital for comfort, clear vision, and long-term eye health. Always consult an eye care professional for proper lens fitting.
How to Assess if Your Contact Lens Size Fits Properly During a Trial?

  1. Check for Lens Movement:
    After wearing the lenses, observe if they frequently shift out of place. If the lenses slide too easily when blinking or moving your eyes, the size might be too large.

  2. Assess Comfort:
    Pay attention to how the lenses feel. If you experience noticeable pressure, pain, or irritation within the first few minutes of wearing them, it could indicate that the base curve is too small or the fit is too tight.

  3. Evaluate Visual Clarity and Stability:
    Test your vision. If objects appear blurry, distorted, or unstable, or if your eyes feel dry or strained, it may not only be due to incorrect lens power or material but also an indication of an improper lens size.

If you notice any of these issues, consult an eye care professional to adjust the lens size or fit for optimal comfort and eye health.

Choosing Contact Lens Color
How to Choose Colored Contact Lenses Based on Skin Tone?

  • Fair Skin

    • Versatile Choices: Fair skin complements a wide range of colors.
    • Light Colors: Shades like light blue, soft pink, or light gray create an ethereal and fresh look, emphasizing the purity of fair skin.
    • Dark Colors: Deep chocolate brown, dark brown, or black enhance depth and definition, making the eyes look more captivating. These pair well with both natural and bold makeup styles.

  • Yellow/Medium Skin

    • Avoid Yellowish Tones: Steer clear of shades that match your skin tone, such as yellow or overly bright hues, as these can dull the complexion and make the eyes look less vibrant.
    • Warm Brown Shades: Colors like caramel, honey, or deep chocolate brighten the eyes and add warmth to your overall look.
    • Cool Green Shades: Olive green or forest green provides a striking contrast, enhancing brightness and offering a chic, fashionable touch.

  • Dark Skin

    • Avoid Pale Colors: Light shades like pastel pink or baby blue may create an unnatural contrast that feels out of place.
    • Deep Tones: Colors like dark brown or black work harmoniously with dark skin, enhancing the natural depth of the eyes.
    • Accents with Sparkle or Gradient: Lenses with golden flecks or deep-toned gradients can add a subtle shine under light, making the eyes pop while maintaining elegance and balance.
How to Choose Colored Contacts for Different Occasions?

  • Neutral Professional Makeup + Dark Brown Lenses: Suitable for meetings or corporate settings.
  • Bold Party Makeup + Bright Colors: Ideal for festive gatherings or themed events.
  • Romantic Smoky Eyes + Wine Red Lenses: Great for candlelit dinners or special occasions.
What Impact Does the Depth of Colored Contact Lenses Have on Eye Appearance?
The depth of colored contact lenses creates distinct visual effects. Lighter shades, such as light blue or light green, make the eyes appear bright and ethereal, giving the impression of an expanded visual range. However, under certain lighting conditions, these colors might make the gaze appear somewhat "unfocused." On the other hand, darker shades, such as black or deep brown, enhance the depth of the eyes, providing a more defined and focused look.

To achieve the appearance of larger eyes, it is generally recommended to choose dark-colored lenses with a slightly larger diameter (within a suitable range, typically not exceeding 14.5 mm). Dark shades outline the eye contours, making them stand out. Slightly increasing the diameter covers more of the cornea and surrounding areas, visually "enlarging" the eyes. However, it's essential to avoid overly large diameters that might cause discomfort or an unnatural appearance.
What Are the Trending Colored Contact Lens Colors?

Currently, a variety of colored contact lens colors are trending:

  • Natural-Looking Colors:

    • "Puppy Eye" Brown: This soft brown tone mimics the pure, innocent look of a puppy's eyes, creating a friendly and lively appearance.
    • "Amber Eyes": Featuring shades of golden yellow and orange-brown, this color appears warm and glossy under light, achieving a balance between natural charm and uniqueness.

  • Fashion-Forward Colors:

    • "Hybrid Blue" and "Hybrid Green": These high-saturation hues exude exotic vibes when paired with sharp facial features and refined makeup, making them perfect for trendsetters seeking a bold statement.
    • "Starry Purple" and "Dreamy Pink": These dreamy shades often include subtle glitter or shimmer, appealing to those who value individuality and romance. These lenses are especially popular for special occasions or creative makeup looks.

In summary, natural tones emphasize warmth and approachability for daily wear, while vibrant, fashion-forward colors cater to those exploring bold and unique styles.
Choosing Contact Lenses Water Content
Is High or Low Water Content Better for Contact Lenses? What Are the Pros and Cons of Each?

  • High Water Content:

    • Advantages:
      • The lenses are softer and provide higher comfort initially.
      • They quickly absorb tears, keeping the eyes moist.
    • Disadvantages:
      • In dry environments, the lenses lose moisture easily, leading to them absorbing water from the eyes, which may cause dryness.
      • High water content does not necessarily mean better oxygen permeability, and dehydration of the lenses over time can cause deformation, affecting vision correction.

  • Low Water Content:

    • Advantages:
      • The lenses are more stable and less prone to deformation.
      • Their oxygen permeability is less dependent on water content, making them suitable for dry environments like air-conditioned rooms or arid climates, as they absorb less moisture from the eyes.
    • Disadvantages:
      • They may feel harder and less comfortable initially, with a stronger foreign body sensation.

In summary, high water content lenses are better for short-term wear or humid conditions, while low water content lenses are more suitable for extended wear or dry environments. The choice depends on individual comfort and the specific wearing conditions.

How to Choose the Right Water Content of Contact Lenses Based on Your Environment (Dry vs. Humid)?

  • Dry Environments (e.g., indoor heating in winter, long periods in air-conditioned spaces, desert areas):

    • It’s recommended to choose contact lenses with a water content of 38% - 42% (low water content).
    • This helps reduce moisture loss from the lenses, preventing them from absorbing water from the eyes and causing dryness.
    • You may also consider using artificial tears to maintain moisture in the eyes.

  • Humid Environments (e.g., rainy seasons, regions with high humidity):

    • Contact lenses with a water content of 50% - 60% (high water content) are more suitable.
    • These lenses can utilize the ambient humidity to maintain their moisture, offering comfort for your eyes.
    • However, it’s important to clean your lenses regularly to prevent the growth of microorganisms.

In summary, if you are in a dry environment, low water content lenses are ideal to prevent dryness, while high water content lenses are better for humid conditions, ensuring comfort and moisture retention.

What effects does wearing contact lenses with high water content for a long time have on the eyes?

Long-term wear of high-water-content contact lenses can have several negative effects on the eyes:

  1. Dryness and Fatigue:
    The lens material continuously loses moisture and starts absorbing moisture from the eyes, leading to dryness and discomfort. This can cause eye fatigue and symptoms of dry eye syndrome.

  2. Vision Instability:
    As the lenses dehydrate and deform, they can affect the accuracy of vision correction, leading to blurred or fluctuating vision.

  3. Increased Risk of Infection and Inflammation:
    A dry environment under the lenses can facilitate the growth of bacteria and microorganisms, increasing the risk of corneal infections and inflammation.

Therefore, it’s important to avoid wearing high-water-content lenses for extended periods and ensure proper care and hydration to minimize these risks.

How To Use And Care For Your Lenses
What are the steps and precautions when wearing contact lenses for the first time?

Here are the steps and precautions for first-time contact lens wearers:

  1. Hand Washing:

    • Wash hands thoroughly with a mild soap or hand wash.
    • Follow the "seven-step handwashing technique," paying special attention to your fingertips, between your fingers, and around your nails.
    • Rinse with running water and dry your hands with a clean towel or tissue to avoid contaminating the lenses with bacteria.

  2. Placing the Lens:

    • Take the lens out of the solution and place it on your fingertip.
    • Ensure the lens is oriented with the correct side up (the edges should form a bowl shape).
    • With the other hand, gently pull up your upper eyelid and use the middle finger of the hand holding the lens to pull down the lower eyelid.
    • Look upward and gently place the lens on the center of your eye.
    • Blink slowly to let the lens settle on your eye. Avoid letting the lens touch your eyelashes or eyelid edges during placement.

  3. Adapting to the Sensation of Foreign Object:

    • It's normal to feel some discomfort when you first wear contact lenses. This feeling typically reduces within a few minutes to half an hour.
    • Try not to rub your eyes. Instead, blink frequently, look at distant objects, or make gentle eye movements to help the lens settle.
    • If the discomfort persists or is accompanied by pain, excessive tearing, or redness, remove the lens immediately. Check for damage, reverse orientation, or any underlying eye issues.

These steps and tips should help you ease into wearing contact lenses comfortably and safely!

Is there a limit to the amount of time I can wear contact lenses each day?

Yes, there is a recommended time limit for wearing contact lenses each day. Typically, it is advised to wear them for no more than 8 to 10 hours per day. Exceeding this limit can have several negative effects:

  1. Oxygen Deprivation: Prolonged wear reduces the amount of oxygen that reaches the cornea, which can lead to corneal edema (swelling) and neovascularization (growth of new blood vessels).

  2. Dry Eyes: Extended use can exacerbate dry eye symptoms, causing discomfort, redness, and irritation.

  3. Blurred Vision: As the cornea struggles to recover, you may experience blurry vision and discomfort.

  4. Long-term Damage: Over time, excessive wear can cause irreversible damage to the cornea, negatively affecting your vision and eye health.

For your eye health, it's essential to stick to recommended wear times and give your eyes adequate rest by removing the lenses at the end of the day.

How should I clean my contact lenses after removing them?

After removing contact lenses, it's important to clean them properly to ensure eye health. Here are the steps:

  1. Never use tap water to clean contact lenses. Tap water contains bacteria, microorganisms, chlorine, and other impurities that can attach to the lenses, increasing the risk of eye infections.

  2. Use a dedicated contact lens solution: Place the lens in the palm of your hand and apply a few drops of the solution. Gently rub both sides of the lens with your fingertips for 10–15 seconds per side. This helps remove proteins, lipids, and other debris that accumulate on the lens surface.

  3. Rinse with saline or fresh solution: After rubbing the lens, rinse it with saline solution or fresh contact lens care solution to ensure it's free of any cleaning residue.

  4. Store properly: Place the lenses in a clean contact lens case filled with fresh solution to keep them safe until next use.

By following these steps and avoiding tap water, you'll maintain the hygiene of your lenses and reduce the risk of infections or irritation.

How often do contact lens cases need to be replaced?

It is recommended to replace your contact lens case every 3 months. Even with regular cleaning, the case may still harbor bacteria and microorganisms, which can contaminate the lenses over time.

To clean the case, first pour out any remaining solution and rinse the inside and outside of the case with tap water. Then, disinfect the case by either:

  • Soaking it in boiling water for 5 to 10 minutes, or using a special lens case disinfectant according to the product's instructions.

After cleaning or disinfecting, allow the case to air-dry completely. Avoid using paper towels to dry it, as they can leave fibers behind that may contaminate the case.

Can a contact lens still be used if it falls on the floor?
If a contact lens falls on the floor, it is not recommended to use it directly. The floor is covered with dust, bacteria, and other contaminants, which can easily cause eye infections if the lens comes into contact with them.

If you must continue using the lens, pick it up immediately and rinse it thoroughly with saline solution or fresh lens care solution for 5-10 minutes. Then, soak the lens in fresh care solution for 4-6 hours. Before wearing it again, carefully check the lens for any damage or scratches. After putting it on, pay close attention to any discomfort, such as redness, pain, or blurred vision. If any of these symptoms occur, remove the lens immediately and seek medical attention.
Wearing Contact Lenses Every Day
What is the recommended maximum wearing time for contact lenses each day?
It is generally recommended to wear contact lenses for no more than 8-10 hours a day. Prolonged wear can cause the cornea to remain in a relatively hypoxic (low-oxygen) state, which affects the normal metabolism of corneal cells. This can lead to various eye problems, such as corneal edema, neovascularization, and dry eye. Early symptoms include dryness, a foreign body sensation, and blurred vision. If the wearing time is not adjusted, long-term misuse can cause irreversible damage to the cornea, which poses a risk to eye health.
What problems can occur from wearing contact lenses continuously for more than 24 hours?

Wearing contact lenses for extended periods, particularly for over 24 hours, significantly worsens corneal hypoxia (lack of oxygen), leading to several issues:

  1. Severe Dryness: The eyes become extremely dry as tear production decreases and evaporation speeds up, making it uncomfortable to wear the lenses.

  2. Redness and Swelling: Blood vessels in the corneal edges dilate in an attempt to supply the cornea with more oxygen. This causes redness and swelling, which are signs of the body’s compensatory response.

  3. Increased Risk of Infection: Prolonged lens wear weakens the eye’s natural defenses, making it easier for bacteria, fungi, and other microorganisms to proliferate. This can lead to infections such as keratitis (corneal infection) or conjunctivitis.

If left untreated, these issues can escalate to more severe conditions, including corneal ulcers, rapid vision loss, and, in extreme cases, even blindness.

What precautions should be taken if you need to take a break from wearing contact lenses during the day?

  1. Storing the lenses when removed:

    • Place the lenses in a clean lens case filled with fresh contact lens solution. Ensure the solution completely covers the lenses.
    • Keep the lens case in a clean, dry, and cool place. Avoid direct sunlight or high-temperature environments, as exposure to heat can cause the lenses to deform or deteriorate.

  2. Checks before wearing the lenses again:

    • Hold the lens up to a light source and check for any damage such as tears, scratches, or deformation. For colored lenses, also check if the color is evenly distributed.
    • Once confirmed, gently rinse the lens with fresh solution before reapplying.
    • Always wash your hands thoroughly before handling the lenses to prevent bacterial contamination.

These steps ensure that your lenses remain in optimal condition and minimize the risk of eye irritation or infection.

What should I pay attention to when wearing contact lenses and looking at the computer for a long time?

For office workers who spend long hours in front of a computer screen, there are several important tips to keep in mind while wearing contact lenses:

  1. Increase Blinking Frequency:

    • Staring at a screen reduces the frequency of blinking, which leads to faster evaporation of tears and discomfort when wearing contact lenses. Make a conscious effort to blink more often. Every 20-30 minutes, intentionally blink 10-15 times to mimic the natural blink rate, helping to distribute tears more evenly and maintain eye moisture.

  2. Take Regular Breaks:

    • Every hour, take a break from the screen. Stand up, stretch, and look at something in the distance for 5-10 minutes. This allows the eyes to rest and helps reduce eye strain caused by prolonged screen time.

  3. Use Artificial Tears:

    • If your eyes feel dry, consider using preservative-free artificial tears to keep your eyes lubricated and minimize irritation from the lenses.

  4. Ensure Proper Screen Positioning:

    • Keep the screen at eye level and at a proper distance (about 20-30 inches away) to minimize strain on the eyes.

These habits help prevent discomfort, eye fatigue, and other negative effects of prolonged contact lens wear and computer use.
Problems and Solutions When Using Lenses
What are the reasons for dry eyes after wearing contact lenses?

  • Environmental Factors: Prolonged exposure to dry environments (such as air-conditioned rooms or winter heating) causes the moisture in contact lenses to evaporate more quickly, which in turn draws moisture from the eyes, leading to dryness.

  • Excessive Wear Time: Wearing contact lenses for too long reduces the oxygen supply to the cornea, which affects tear production and leads to reduced moisture on the surface of the eyes.

  • Incorrect Lens Water Content: Lenses with high water content tend to dehydrate more quickly in dry environments, while lenses with low water content may initially feel less comfortable, potentially leading to dryness.

  • Pre-existing Dry Eye Conditions: If you have underlying eye conditions like dry eye syndrome, wearing contact lenses may worsen the symptoms, making the dryness more noticeable.

How to solve dry eyes after wearing contact lenses?

  • Use Artificial Tears: Opt for preservative-free or low-preservative artificial tears to maintain moisture. Apply 3-6 times a day based on the severity of dryness. Choose products suitable for contact lens wearers.

  • Adjust Lens Water Content: Choose contact lenses with appropriate water content based on the environment. For dry environments, select lenses with lower water content; for more humid environments, opt for higher water content lenses.

  • Reduce Wear Time: Limit wearing contact lenses to the recommended 8-10 hours per day to prevent excessive dryness and allow the eyes time to recover.

  • Seek Medical Advice for Pre-existing Conditions: If you have a condition like dry eye, it's essential to consult with an eye care professional. They may recommend treatments or, if necessary, advise you to stop wearing contact lenses temporarily.

I feel a foreign body sensation after wearing the lenses. What are the possible reasons?

  • Lens Quality Issues: Imperfections such as an uneven surface, manufacturing defects, or poor-quality materials can cause discomfort and a feeling of something in the eye.

  • Incorrect Lens Size: If the base curve is too steep or too flat, or if the diameter is too large or too small, the lens may not fit properly on the cornea, leading to friction and a foreign body sensation.

  • Improper Handling or Wearing: Wearing the lens inside out, contaminating the lens with dirt or oils during handling, or rough placement of the lens can all contribute to discomfort.

How to Identify and Resolve the Problem?

  • Check If the Lens Is Inside Out:
    Remove the lens and place it on your fingertip to check its shape. The correct side will look like a smooth bowl (with edges curving upwards), while an inside-out lens will have edges that flare out slightly. If the lens was inside out, place it correctly and observe if the discomfort improves.

  • Inspect the Lens:
    Hold the lens up to a light source and examine it for scratches, tears, or foreign particles. If any damage or contamination is visible, discard the lens and use a fresh one.

  • Confirm Lens Size and Fit:
    Review the lens parameters (base curve and diameter) compared to your prescription. If the size is incorrect or if discomfort persists despite proper placement, visit your eye care provider to check the fit and ensure compatibility.

  • Follow Proper Handling Practices:

    • Wash your hands thoroughly before handling lenses to prevent contamination.
    • Use fresh lens solution to rinse and clean the lens before wearing.
    • Place the lens gently on your eye without pressing too hard, and avoid contact with eyelashes.
By systematically checking these factors, you can pinpoint the cause of the discomfort and take the appropriate corrective action. If the issue persists, consult an eye care professional.
What are the emergency measures if the contact lenses suddenly slip off while being worn?

If the lens slips or falls:

  1. Immediately stop your current activity and try to remain stationary to avoid stepping on the lens.
  2. Lower your head slightly and use your fingers to gently hold your eyelids open.
  3. With the help of a light source, locate the lens.
    • If the lens is still in your eye, blink gently to see if it repositions itself naturally.
    • If it doesn’t, use a clean finger or disinfected tweezers to carefully remove the lens.
  4. If the lens has fallen to the ground, follow the previously mentioned cleaning and disinfecting steps to handle a dropped lens.
How to prevent contact lenses from slipping off suddenly while wearing?
  1. Choose the Right Lens Size and Type: Ensure the lens fits well and adheres securely to your eye.
  2. Inspect the Lens Before Use: Check for any damage, deformation, or imperfections to ensure the lens is in good condition.
  3. Use Artificial Tears: Before engaging in activities that may displace the lens (e.g., physical exercise), apply artificial tears to improve lens adherence.
  4. Avoid Touching or Rubbing Your Eyes: Minimize external forces or sudden movements that could disrupt the lens’s position.

By following these precautions, you can reduce the risk of lens slippage and ensure a more comfortable wearing experience.

What should I do if my eyes are red and inflamed and I suspect contact lenses cause them?

  1. Immediately Stop Wearing Contact Lenses:
    Remove the lenses carefully and set them aside.
