Can certain eye conditions can affect your ability to wear contact lenses?

Yes, but there are specialized lenses or management techniques that can help. Here’s a breakdown of common conditions that may impact contact lens wear and how they can be addressed:

1. Dry Eye Syndrome:

  • What It Is: Dry eye occurs when the eyes don’t produce enough moisture or the right quality of tears. It can lead to discomfort, redness, blurred vision, and irritation.
  • How It Affects Contact Lens Wear:
    • Dry eyes can make wearing contact lenses uncomfortable, as lenses may cause additional dryness or irritation.
  • Solutions:
    • Hydraglyde/High-Moisture Lenses: Specialized soft lenses with moisture-retention properties.
    • Daily Disposable Lenses: These lenses are replaced daily and may help reduce dryness as they come with less buildup of debris or proteins.
    • Scleral Lenses: Large-diameter lenses that create a reservoir of moisture over the cornea, helping to alleviate dryness.
    • Artificial Tears or Lubricating Drops: To keep the eyes hydrated while wearing lenses.

2. Astigmatism:

  • What It Is: Astigmatism occurs when the cornea (the front surface of the eye) is irregularly shaped, causing blurred or distorted vision at all distances.
  • How It Affects Contact Lens Wear:
    • Standard spherical lenses won't correct astigmatism.
    • Without proper lens fitting, blurry vision and discomfort may occur.
  • Solutions:
    • Toric Contact Lenses: These are specially designed to correct astigmatism. They have a different curvature and are available in both soft and rigid gas-permeable (RGP) forms.
    • Scleral Lenses: For more severe cases of astigmatism, scleral lenses provide excellent vision correction and comfort.

3. Keratoconus:

  • What It Is: Keratoconus is a condition where the cornea becomes thin and cone-shaped, causing distorted and blurry vision.
  • How It Affects Contact Lens Wear:
    • Keratoconus can be difficult to correct with standard contacts due to the irregular corneal shape.
  • Solutions:
    • Scleral Lenses: These large-diameter lenses vault over the cornea, creating a smooth surface for better vision and comfort.
    • Rigid Gas-Permeable (RGP) Lenses: Often used for keratoconus because they help maintain a stable tear film and correct vision distortions.

4. Eye Allergies:

  • What It Is: Allergies can cause itching, redness, and watery eyes, often aggravated by pollen, dust, or pet dander.
  • How It Affects Contact Lens Wear:
    • Allergies can irritate the eyes when wearing contacts, leading to discomfort, increased dryness, and blurred vision.
  • Solutions:
    • Daily Disposable Lenses: Reduce the buildup of allergens on lenses, offering a fresh, clean lens every day.
    • Anti-Allergy Eye Drops: Use eye drops formulated for allergy relief.
    • Scleral Lenses or Rigid Lenses: These can help shield the eye from allergens.

5. Giant Papillary Conjunctivitis (GPC):

  • What It Is: GPC is a condition often caused by contact lens wear, especially if lenses are not cleaned properly. It involves the formation of large bumps on the inner eyelids, leading to irritation and discomfort.
  • How It Affects Contact Lens Wear:
    • GPC can make contact lenses uncomfortable, causing itching, redness, and blurred vision.
  • Solutions:
    • Improved Lens Hygiene: Switching to daily disposable lenses or more frequent cleaning routines can help prevent GPC.
    • Scleral Lenses: These lenses are less likely to irritate the eyes, as they don’t touch the cornea directly.

6. Age-Related Vision Changes (Presbyopia):

  • What It Is: Presbyopia is the age-related loss of near vision, typically starting around age 40.
  • How It Affects Contact Lens Wear:
    • People with presbyopia need a correction for both near and distance vision.
  • Solutions:
    • Multifocal Contact Lenses: These lenses offer different powers in one lens, allowing for clear vision at near, intermediate, and far distances.
    • Monovision: One eye is corrected for near vision, and the other is corrected for distance vision. This can be achieved with contact lenses or a combination of contacts and glasses.

7. Corneal Scarring or Injury:

  • What It Is: Scarring or injury to the cornea can result in blurred vision, discomfort, or sensitivity to light.
  • How It Affects Contact Lens Wear:
    • Scarring can make the cornea less stable for lenses, leading to irritation or difficulty wearing lenses comfortably.
  • Solutions:
    • Scleral Lenses: These lenses can help protect the damaged cornea and provide more comfort than traditional lenses.
    • Custom Rigid Gas-Permeable Lenses: These lenses can be tailored to fit the specific shape of your eye.

How to Know if You’re a Candidate for Contact Lenses:

  1. Consult an Optometrist:
    • A comprehensive eye exam is needed to assess your eye health, prescription, and the best type of contact lenses for your condition.
  2. Contact Lens Fitting:
    • A proper fitting is essential for comfort and visual clarity. Specialized lenses may be recommended depending on your condition.
  3. Ongoing Care:
    • Regular follow-ups with your eye doctor ensure your lenses are working well and your eyes remain healthy.

Even if you have conditions like dry eye or astigmatism, there are many contact lens options available. Your optometrist can help you find the best solution to suit your eyes and lifestyle.
