Dry eyes, characterized by a gritty sensation, burning, or redness, are a common challenge for many contact lens wearers. This discomfort arises when the eyes do not produce enough tears or the tears are of insufficient quality. Contact lenses can sometimes worsen this condition. Fortunately, effective strategies exist to manage dry eye symptoms, allowing for more comfortable lens wear.
Understanding Why Contacts Cause Dryness
Contact lenses contribute to dry eyes by interacting with the natural tear film on the eye’s surface. A lens on the cornea disrupts this film, leading to increased tear evaporation and reduced moisture.
Reduced oxygen flow to the cornea is another factor, as contact lenses can partially block oxygen, impacting natural tear production. Friction between the lens and eyelid during blinking can also cause irritation. Over time, protein and lipid deposits can accumulate on the lens surface, further contributing to discomfort and dryness.
Immediate Relief and Daily Practices
For immediate relief from dry eyes while wearing contact lenses, use specific re-wetting drops designed for lens wearers. These drops, also known as artificial tears, provide quick hydration and reduce friction. If used frequently, choose preservative-free options to avoid further irritation. Apply a drop in each eye as needed throughout the day for improved comfort.
Conscious blinking is another effective practice, especially during extended screen time, as digital devices reduce the natural blink rate. Follow the 20-20-20 rule: look at an object 20 feet away for 20 seconds every 20 minutes to alleviate eye strain and dryness.
Contact Lens Hygiene
Proper contact lens hygiene is important. Always wash hands with soap and water before handling lenses. Use fresh, recommended cleaning solution for reusable lenses, and never use water or saliva, which can introduce bacteria. Avoid sleeping in contact lenses unless approved for extended wear, to prevent complications like infections and increased dryness.
Long-Term Solutions and Lifestyle Adjustments
For a sustained approach to managing dry eyes with contact lenses, exploring different lens types can make a substantial difference. Daily disposable lenses are often recommended because they minimize the buildup of deposits and allergens, as a fresh pair is used each day. Silicone hydrogel lenses are another beneficial option, as their material allows more oxygen to reach the eye, which helps maintain moisture. Some lenses are specifically designed with technologies like water gradient or moisture-retaining properties to enhance hydration.
Beyond lens choices, lifestyle adjustments can significantly contribute to eye comfort. Ensuring adequate hydration by drinking plenty of water helps maintain overall body hydration, including the eyes. Using a humidifier in dry environments, such as air-conditioned rooms, can add moisture to the air and reduce tear evaporation. Dietary considerations, such as incorporating Omega-3 fatty acids found in flaxseed, salmon, or supplements, may help reduce inflammation and improve tear quality. Consulting an eye care professional is advisable to determine the most suitable lens type and receive personalized recommendations for long-term management.
When to Seek Professional Help
While many dry eye symptoms can be managed with self-care, certain signs indicate the need for a professional evaluation. If discomfort persists or worsens despite trying home remedies and over-the-counter solutions, a visit is warranted. Symptoms such as persistent redness, pain, fluctuating or blurred vision, or frequent eye infections should prompt immediate attention. An eye care professional can accurately diagnose the underlying cause of your dry eyes, which might include specific medical conditions or medication side effects. They can then recommend prescription treatments, specialized contact lenses like scleral lenses, or discuss alternative vision correction options to ensure lasting relief and preserve eye health.
