Why Does One Gas Perm Lens Feel Scratchy?
Understanding Gas-Permeable Lenses
Gas-permeable lenses are rigid, smaller than soft contact lenses, and designed to sit on the cornea while allowing oxygen to pass through. Unlike soft lenses, GP lenses maintain their shape, providing sharper vision, especially for individuals with astigmatism or other refractive errors.
Key Benefits of GP Lenses
- Enhanced Oxygen Permeability: Allows the cornea to “breathe,” reducing the risk of corneal hypoxia.
- Durability: Resistant to tearing and buildup of deposits.
- Sharper Vision: Offers crisper vision compared to soft lenses, particularly for irregular corneas.
- Cost-Effective Over Time: Despite higher initial costs, GP lenses can last longer with proper care.
However, these lenses can take longer to adjust to, and even seasoned wearers may experience discomfort under certain conditions.
Why Does One Gas Perm Lens Feel Scratchy?
Experiencing discomfort in one eye can be frustrating. Below are the primary reasons why a gas-permeable lens might feel scratchy:1. Foreign Particles Under the Lens
One of the most common reasons for scratchiness is the presence of debris, such as dust, lint, or makeup particles, under the lens. Since GP lenses do not cover the entire cornea like soft lenses, debris can easily get trapped underneath.
- Symptoms: Sudden onset of discomfort, watering, or a sensation of something in the eye.
- Solution: Remove the lens, rinse it thoroughly with the recommended cleaning solution, and inspect for debris.
2. Lens Fit Issues
A poorly fitted lens can cause uneven pressure on the cornea, leading to irritation. This could be due to changes in corneal shape over time or improper measurements during the fitting process.
- Symptoms: Persistent discomfort, redness, or blurriness in one eye.
- Solution: Consult your optometrist for a refitting. An adjusted lens can alleviate discomfort.
3. Lens Damage
Even though GP lenses are durable, scratches, chips, or warping can occur, especially if mishandled. A damaged lens can feel rough and irritate the cornea.
- Symptoms: Persistent scratchiness despite cleaning and proper insertion.
- Solution: Examine the lens under bright light for visible damage. Replace it if needed.

4. Protein or Lipid Deposits
Over time, deposits from tears can accumulate on the lens surface, causing irritation. These deposits may be more pronounced in one lens due to variations in tear production or eye anatomy.
- Symptoms: Gradual onset of discomfort and cloudy vision.
- Solution: Use enzymatic cleaning solutions or consult your optometrist for a professional cleaning.
5. Dry Eyes
Dry eye syndrome can exacerbate the scratchy feeling, particularly with GP lenses that require a consistent tear film for optimal comfort.
- Symptoms: Burning sensation, itchiness, and the feeling of “grit” in the eye.
- Solution: Use preservative-free artificial tears designed for contact lenses and ensure proper hydration.
6. Incorrect Lens Placement
Improper lens insertion can cause discomfort. The lens may sit off-center or not align correctly with the cornea.
- Symptoms: Immediate discomfort upon insertion and fluctuating vision.
- Solution: Reinsert the lens, ensuring it is centered on the cornea.
7. Underlying Eye Conditions
Corneal abrasions, infections, or conditions like keratoconus can make one lens feel scratchy. These conditions may require medical intervention.
- Symptoms: Persistent pain, redness, light sensitivity, or blurred vision.
- Solution: Seek immediate attention from an eye care professional.
Tips for Preventing Lens Discomfort
To minimize the likelihood of experiencing scratchy GP lenses, follow these preventative measures:
1. Adopt a Strict Cleaning Routine
- Rinse and clean your lenses daily using the prescribed cleaning solution.
- Avoid using tap water or saliva, as they can introduce harmful bacteria.
2. Handle with Care
- Use your fingertips (not nails) to handle lenses to avoid scratches.
- Store lenses in a clean case filled with fresh solution after each use.
3. Regular Check-Ups
Visit your optometrist regularly to ensure your lenses fit well and your prescription is up to date.
4. Maintain Good Eye Hygiene
- Remove makeup before inserting lenses.
- Wash your hands thoroughly before handling lenses.
5. Hydrate Your Eyes
Use lubricating drops to keep your eyes moist, especially in dry environments.

Frequently Asked Questions (FAQs)
Q1: Can scratchy GP lenses damage my eyes?
Yes, prolonged use of a scratchy GP lens can lead to corneal abrasions or infections. If discomfort persists, it’s crucial to remove the lens and consult your optometrist.
Q2: How long does it take to adjust to GP lenses?
Most people adapt within 1-2 weeks. If discomfort persists beyond this period, it could indicate a fitting issue or another problem.
Q3: How often should I replace my GP lenses?
GP lenses can last for 1-2 years with proper care. However, replace them immediately if they are damaged or warped.
Q4: Can I wear GP lenses if I have dry eyes?
Yes, but managing dry eyes with lubricating drops and proper hydration is essential to ensure comfort.
Q5: What should I do if a lens feels scratchy even after cleaning?
Inspect the lens for damage, ensure proper insertion, and consult your optometrist if the problem persists.
Q6: Are GP lenses better than soft lenses?
GP lenses offer sharper vision and are more durable, but soft lenses are often more comfortable for first-time users. The choice depends on individual needs and preferences.
By understanding the potential causes of scratchiness in one GP lens, you can take proactive steps to ensure a comfortable and problem-free experience.
