Understanding the Causes and Solutions for Contact Lens-Related Dry Eyes

Comprehensive insights into dry eyes caused by wearing contact lenses

Experiencing discomfort, burning, or scratching sensations while using contact lenses? Redness and sensitivity may also occur, indicating dry eye issues. While contact lenses can contribute to dryness, other factors might be involved.

How to identify if you have dry eyes

If your eyes feel burning, produce excess mucus, and are overly sensitive to light, you likely suffer from dry eyes.

Blurry vision or tired eyes are common signs of dry eyes.

If symptoms persist, consulting a healthcare professional is important to prevent future eye health issues.

Removing contact lenses during symptoms can help reduce dryness, as lenses can exacerbate the problem.

Role of tears in maintaining corneal health

The tear film, a thin protective layer over the eyes, contains more than just water—it's crucial for protecting against infections and irritants.

The cornea relies heavily on this tear film for oxygen, as it lacks a dedicated oxygen supply. Tears facilitate oxygen transfer from the atmosphere to the eye.

Wearing contact lenses can cover the cornea and displace this tear film, limiting oxygen flow and leading to dryness.

Many eye specialists have researched how contact lenses impact tear production and eye comfort.

Which types of contact lenses should you avoid to prevent dry eyes?

Opt for lenses that do not disturb the tear film covering the cornea.

Avoid lenses that are not gas-permeable, as they tend to dry out the eyes.

Lenses that hinder oxygen flow or displace tears can lead to dryness and discomfort.

Choosing the right contact lenses for dry eyes

Gas-permeable lenses are excellent because they allow oxygen passage and do not interfere with the tear film.

Hydrophilic soft lenses that are gas-permeable are a newer option—these retain water while permitting oxygen transfer.

Such lenses help maintain eye hydration and oxygen levels, reducing dryness risks.

Are contact lenses the sole cause of dry eyes?

No, contact lenses are just one possible factor.

Lack of tear production, often due to aging, medications, or medical conditions like diabetes, also causes dry eyes.

Other causes include radiation or inflammation damaging tear glands, or recent ocular surgeries.

Additional risk factors for dry eyes beyond contact lens use

Gender: Women are more prone to dry eyes due to hormonal fluctuations affecting tear production.

Vitamin A deficiency: Essential for tear production; insufficient intake from dietary sources like carrots or leafy greens can increase susceptibility.
