Contact lenses have revolutionized the world of vision correction, offering millions of people a comfortable alternative to glasses. However, contact lens wearers face unique challenges, including the effects of dehydration on their eye health. Dehydration, a condition where the body lacks sufficient water, can have a profound impact on various bodily functions, extending to contact lens wearers as well. In this article, we will delve into the intricate relationship between dehydration and contact lenses, exploring the effects, prevention strategies, and management techniques to ensure optimal eye health.

Understanding Dehydration and its Impact

Dehydration occurs when the body loses more fluids than it takes in, leading to an imbalance in the body’s water content. Factors such as excessive sweating, inadequate fluid intake, or dry environmental conditions can contribute to dehydration. When the body becomes dehydrated, it prioritizes the preservation of vital organs like the brain and heart, which often results in reduced fluid supply to less essential areas, such as the eyes. If you’re a contact lens wearer seeking optimal moisture and comfort, consider using lenses such as Acuvue Oasys contacts, which have been specifically designed to address these needs.

Dehydration’s Effect on the Eyes

Dryness and Irritation: Dehydration diminishes tear production, causing the eyes to become dry and irritated. For contact lens wearers, this discomfort is heightened, making it challenging to wear lenses for extended periods. Contact lenses require a certain level of moisture to maintain their proper function and provide a comfortable wearing experience. However, when the eyes are dehydrated, the tears become insufficient to lubricate the contact lens and the surface of the eye. As a result, the lenses can cause friction, leading to discomfort, redness, and a gritty or foreign body sensation.

Increased Friction: Insufficient moisture in the eyes leads to increased friction between the contact lens and the cornea. This friction can result in discomfort, blurred vision, and an elevated risk of corneal abrasions. When the eyes lack sufficient moisture, the surface of the cornea becomes dry and rough. As a result, when the contact lens moves across the cornea during blinking or eye movements, the dry surfaces rub against each other. This increased friction can cause discomfort, irritation, and a feeling of grittiness or scratching sensation.

Protein Build-up: Tears play a crucial role in lubricating the eyes and washing away debris and proteins that can accumulate on the surface of contact lenses. Dehydration reduces tear production, increasing the likelihood of protein deposits on the lenses. These deposits can cause blurred vision, discomfort, and elevate the risk of eye infections.

Preventing Dehydration-Related Issues

Hydration is Key: Staying adequately hydrated is essential for overall health and eye comfort. It is recommended to drink at least eight glasses of water per day and increase fluid intake during hot weather or physical activities.

Lubricating Eye Drops: Tears serve as a natural lubricant for the eyes, and they also help remove debris and proteins that can accumulate on the surface of contact lenses. However, dehydration reduces tear production, which increases the likelihood of protein build-up on the lenses. This can lead to various issues for contact lens wearers, including blurred vision, discomfort, and an elevated risk of eye infections. When tears are insufficient due to dehydration, the normal cleansing mechanism is compromised. Proteins present in tears, along with other substances, can accumulate on the surface of contact lenses over time. 

Limiting Environmental Factors: Excessive exposure to dry environments, such as air-conditioned rooms or windy areas, can increase the risk of dehydration-related eye problems. Using a humidifier in dry indoor spaces can help maintain moisture levels.

Managing Dehydration-Related Discomfort

Remove and Rest: If you experience significant discomfort or dryness while wearing contact lenses, it is crucial to listen to your body and take appropriate action. Removing your contact lenses and allowing your eyes to rest can be immensely beneficial in relieving discomfort and promoting eye hydration and recovery. When you remove your contact lenses, you eliminate the potential source of friction and irritation on the surface of your eyes. This break allows your eyes to breathe and regain their natural moisture balance. By taking off your lenses, you give your eyes a chance to replenish the tears that are essential for lubrication and nourishment.

Soak and Clean: Proper contact lens hygiene is crucial for all wearers, but it becomes even more important for those experiencing dehydration-related issues. Thoroughly clean and soak your lenses using the recommended solution to minimize the risk of protein build-up and infections.

Consult an Eye Care Professional: If dehydration-related symptoms persist or worsen despite preventive measures, it is crucial to seek advice from an eye care professional. They can assess your condition, recommend appropriate treatment, or suggest alternative contact lens options if necessary.

Dehydration presents unique challenges for contact lens users, leading to dryness, discomfort, and an increased risk of eye infections. Prioritizing hydration, maintaining proper lens hygiene, and seeking guidance from eye care professionals are essential steps for contact lens wearers to prevent and manage dehydration-related issues. By following these recommendations, contact lens users can enjoy comfortable and safe vision correction while minimizing the impact of dehydration on their eye health.
