Contact lenses are used for convenience, a wider field of vision, an active lifestyle, and sometimes for cosmetic purposes. Generally, they are used for vision correction in place of a pair of glasses. However, they also come with a set of challenges, one of the most common being dry eye syndrome. In the area of vision correction, along with lens use, even LASIK surgery causes dry eye syndrome. Dry eye is a condition where the eyes do not produce enough tears to keep the eyes lubricated or the right quality of tears that the eye needs to work. For contact lens wearers, this can be particularly frustrating, as the lenses themselves can exacerbate symptoms of dryness, irritation, and discomfort. Fortunately, there are multiple strategies and methods that can help manage dry eye conditions for contact lens users, improving both comfort and eye health.
Why contact lens cause dry eye condition?
For contact lens wearers, dry eye can become more problematic, as the lenses can interfere with the eye’s natural lubrication system. Dry eye condition that occurs due to contact lens is referred as CLD (Contact Lens-Associated Dry Eye Disease). In CLD contact lenses disrupt the natural tear film on the eye by blocking oxygen flow to the cornea, absorbing moisture from tears, and creating friction between the lens and the eye surface, leading to a thinner, unstable tear film that evaporates more quickly, resulting in a dry, gritty sensation; This is particularly true if the lenses are poorly fitted, in air-conditioned environment, dry weather or worn for extended periods of time. The difficulty of eyes to maintain an adequate level of moisture, leads to irritation, redness, a gritty or sandy sensation, blurry vision, and even light sensitivity.
Therefore, the key points that contribute to dry eyes are;
Tear film disruption
Oxygen barrier
Moisture absorption
Friction
Possible causes of dry eye in contact lens wearers
Several factors can contribute to dry eyes for contact lens users:
Lack of tear production. The production of tears may be insufficient already, either due to underlying medical conditions or natural aging processes. Contact lenses can increase the tear evaporation rate, further contributing to dryness.
Poorly fitting lenses. Lenses that do not fit properly or are not suited for your eyes can irritate the surface of the eye, leading to discomfort and dryness.
Lens material. Some contact lenses are made from materials that absorb moisture, which can exacerbate dryness. It is essential to select lenses made from highly breathable materials that allow for better moisture retention.
Over-wearing lenses. Wearing contact lenses for extended periods or overnight, when not approved for such use, can reduce oxygen flow to the cornea and affect the tear film, resulting in dryness.
Environmental factors. Dry, windy, or air-conditioned environments can increase tear evaporation and aggravate dry eye symptoms for contact lens users.
What do you do to manage dry eyes in case of contact lenses?
If you suffer from dry eyes and are a contact lens user, here are practical steps to help manage and alleviate the condition:
Choose the right type of contact lenses
The first step in managing dry eye is choosing the right contact lenses. There are many types of lenses designed specifically for people with dry eyes, such as:
Silicone hydrogel Lenses, Daily Disposable Lenses, Hydraglyde or Moisture-Seal Lense. Consult with your eye care provider to determine which lens type is best for you.
Use artificial tears - Eyespa eye drops
One of the most effective ways to combat dryness during the day is by using artificial tears designed for contact lens wearers such as Sodium carboxymethyl cellulose (CMC) eye drops. These lubricating drops are specifically formulated to hydrate both the eyes and the lenses, providing relief from dryness and discomfort.
It is essential to use drops that are compatible with your type of contact lenses. Avoid using common drops that are not formulated for contact lens wearers. Eyespa eye drops made with all care for contact lens users to deal with dry eye condition.
Maintain proper lens hygiene
Proper lens hygiene is crucial for maintaining eye health and preventing dryness. Always follow the cleaning and disinfection instructions recommended by your eye care provider and the contact lens manufacturer. This includes:
Wash your hands before touching your lenses.
Maintain lens case hygiene by cleaning the lens case regularly and replace it every 3 to 6 months to prevent bacterial growth.
Never expose your lenses to water including tap water or swimming pools.
Take breaks
If you experience dry eyes, it may help to take breaks from wearing your contact lenses. Overusing contact lenses can cause the eyes to become tired and dried out. Give your eyes a rest by switching to glasses for a few hours each day or as necessary.
Stay hydrated and maintain with eye nutrition
Proper hydration plays an essential role in eye health. Dehydration can cause dryness in the body and even the eyes. Therefore, make sure to drink plenty of water throughout the day. A well-hydrated body helps maintain a sufficient tear production rate, which is crucial for keeping the eyes moist.
Additionally, eating foods rich in omega-3 fatty acids, vitamin A, lutein and zeaxanthin. They may help improve tear quality and reduce inflammation, both of which can benefit individuals suffering from dry eye syndrome.
Optimize your environment
Environmental factors play a very crucial role in exacerbating dry eye symptoms. To reduce the impact of environmental irritants, consider:
Using a humidifier in your home or office can help maintain moisture levels in the air and prevent excessive tear evaporation.
Limit the exposure to air conditioning and fans
Wear sunglasses
Regular eye checkups
It is essential to schedule regular visits with your eye care provider to monitor your eye health, especially if you experience symptoms of dry eye. Your provider can assess your tear production, evaluate the health of your cornea, and make recommendations for managing dry eyes.
If your dry eye symptoms persist despite trying the above suggestions, it is important to seek professional advice. Continuous irritation or blurry vision may indicate an underlying condition that requires medical intervention.
Managing dry eye syndrome as a contact lens user requires a combination of lifestyle adjustments, proper eye care, and, in some cases, a change in the type of lenses used. Always consult with your eye care professional to address your needs and ensure that you continue to enjoy the benefits of wearing contact lenses without the discomfort of dry eyes.
