For individuals with dry eyes, wearing contact lenses can often feel like an uncomfortable trade-off for clear vision. However, advancements in contact lens technology have led to the development of options that cater to those prone to dryness, offering relief and improved comfort. This article delves into the causes of dry eyes, the impact of contact lenses on this condition, and the innovative solutions available to contact lens wearers.
Understanding Dry Eye Syndrome and Contact Lenses
Dry eye syndrome affects millions worldwide, with prevalence increasing with age. According to the National Eye Institute, nearly 5 million Americans aged 50 and older suffer from significant dry eye symptoms. The condition arises when the eyes do not produce enough tears or when the tears evaporate too quickly, leading to irritation and discomfort.
Factors Contributing to Dry Eyes:
- Natural Tear Production: Some individuals naturally produce fewer tears, or their tears may lack the necessary chemical composition for proper eye lubrication.
- Environmental Conditions: Working in environments with air conditioning, heating, or exposure to smoke, dust, or wind can exacerbate dryness.
- Digital Screen Use: Prolonged computer use can reduce blinking frequency, which is essential for spreading tears and keeping the eyes moist.
- Contact Lens Materials: Traditional soft contact lenses, often composed of polymers and high water content, can contribute to dry eye by losing moisture throughout the day.
Soft Contact Lenses Designed for Dry Eyes
Lens manufacturers have recognized the need for more comfortable options for those with dry eyes. By innovating materials and designs, they have created lenses that retain moisture more effectively.
Low Water Content Lenses:
Modern silicone hydrogel lenses, such as those with around 30% water content, are less likely to dehydrate compared to traditional lenses with 50-60% water content. These lenses are designed to minimize moisture loss and maintain comfort.
Top Picks for Dry Eye Sufferers:
- Acuvue Oasys (Johnson & Johnson Vision): These lenses incorporate Hydraclear Plus technology, which integrates a rewetting agent to keep the lenses moist, even in dry conditions. Made from senofilcon A, Acuvue Oasys lenses are bi-weekly disposables intended for daily wear.
- Proclear Compatibles (CooperVision): Constructed from omafilcon A, these lenses have shown high on-eye water retention in clinical studies. Proclear lenses utilize biocompatibility technology, featuring phosphorylcholine (PC), a substance found naturally in human cells, to reduce the body’s tendency to reject the lens. These are monthly disposables that offer a silky, hydrated feel.
Rigid Gas Permeable (RGP) Lenses: An Alternative for Dry Eyes
For some, Rigid Gas Permeable (RGP) lenses are recommended. These lenses are made from polymeric materials without water content, eliminating the issue of evaporation. However, they can be uncomfortable for those with insufficient tear production due to their rigidity.
Making the Right Choice for Comfortable Vision
If you’re struggling with dry eyes and contact lens discomfort, you don’t have to settle for irritation. Consult with your eye care professional to determine if the aforementioned lenses or other specialized options might be suitable for you. With the right choice, you can achieve clear vision without compromising on comfort.
