Contact Lens-Induced Dry Eye (CLIDE) affects many contact lens wearers, causing discomfort and irritation. It's crucial to recognize the symptoms and seek the right care to maintain clear, comfortable vision. Practices listed with Specialty Vision are here to help you with effective management options.
Contact Lens-Induced Dry Eye (CLIDE) is a specific form of dry eye that occurs or gets worse when wearing contact lenses. Many people experience dry, irritated, or uncomfortable eyes while wearing contacts, which can impact daily activities such as reading, working on a computer, or driving. Understanding CLIDE is essential for maintaining clear, comfortable vision, and sometimes, minor adjustments in your routine can dramatically improve your lens-wearing experience.
CLIDE is a dry eye condition directly related to contact lens wear, distinct from other general forms of dry eye. While regular dry eye can affect anyone, CLIDE specifically arises from the interaction between contact lenses and the eye's surface, but with the right care, most people can manage it effectively.
Regular dry eye syndrome can be caused by aging, environment, medications, or health issues, often unrelated to contact lenses. CLIDE, on the other hand, is triggered or worsened by the presence of a contact lens on the cornea. The lens can disrupt the natural tear film that keeps eyes moist, making symptoms more prominent during lens wear and often improving when lenses are removed.
Contact lenses sit directly on the tear film that covers your eye surface. This thin layer of tears has three parts: an outer oily layer, a middle watery layer, and an inner mucus layer. When a lens disrupts this delicate balance, it can cause tears to evaporate faster or become less stable, leading to the uncomfortable symptoms of CLIDE.
Anyone who wears contact lenses can develop CLIDE, but certain groups are at higher risk. People over 40, women due to hormonal influences, individuals living in dry or windy environments, and those with a history of allergies or systemic conditions like Sjögren's syndrome are more susceptible. Studies show that between 30% and 50% of contact lens users report dry eye symptoms, especially during long hours of wear.
CLIDE can make your eyes feel gritty, tired, or burning, which might limit how long you can comfortably wear lenses each day. It can interfere with work productivity, sports performance, or hobbies if not addressed. Persistent symptoms may also lead to corneal irritation, increasing the risk of eye infections or developing an intolerance to lenses.
Several factors related to contact lenses, your daily habits, and your environment can trigger CLIDE. Knowing these causes allows you to make smart changes to keep your eyes comfortable and your vision clear.
Older hydrogel lenses are less breathable and may contribute to dryness compared to modern silicone hydrogel lenses, which allow more oxygen to reach the cornea. Lenses with very high water content may actually draw moisture away from your eyes to stay hydrated. A poorly fitting lens can also cause mechanical friction, disrupting the tear film and leading to dryness.
Wearing lenses beyond the prescribed replacement schedule increases the risk of protein and lipid deposits on the lens surface, which can irritate the eyes. Sleeping in lenses not approved for overnight wear is a significant risk factor. Even wearing daily lenses for too many hours without breaks can contribute to dryness, as your eyes need time to recover.
Dry air from heaters, air conditioners, fans, or windy outdoors can accelerate tear evaporation. Occupations involving prolonged screen time can reduce your blink rate from about 15-20 blinks per minute to as few as 5, exacerbating dryness. Exposure to smoke, pollution, dust, or chemical fumes can also irritate the ocular surface.
Medications such as antihistamines, diuretics, oral contraceptives, and some antidepressants can decrease tear production. Chronic dehydration, a diet low in omega-3 fatty acids, and systemic conditions like diabetes or rheumatoid arthritis may also predispose individuals to CLIDE. Stress and lack of sleep can negatively impact ocular surface health.
Some multipurpose contact lens solutions contain preservatives that can build up on lenses and irritate sensitive eyes. Using expired solutions, not rubbing lenses during cleaning, or reusing old solution can lead to deposits that worsen dryness. Even old or contaminated lens cases can harbor bacteria that contribute to irritation.
CLIDE symptoms can range from mild discomfort to persistent irritation that interferes with lens use. Recognizing these symptoms early is key to preventing them from impacting your quality of life and eye health.
Symptoms often include dryness, a scratchy or gritty feeling, burning, and redness, especially toward the end of the day. Some people notice blurry vision that clears up after blinking or using eye drops. Difficulty keeping lenses in place or excessive lens awareness are also common complaints.
In more severe cases, symptoms may include excessive tearing (reflex tearing), sensitivity to light, and a sensation of eye fatigue. Severe CLIDE can lead to an intolerance of contact lenses, prompting you to remove them prematurely. Prolonged, untreated symptoms increase the risk of corneal abrasions or infections.
While most CLIDE symptoms are manageable, some signs need prompt care. These include severe eye pain, significant vision changes, thick or colored discharge, extreme light sensitivity, or symptoms that worsen rapidly. These could indicate an infection or another serious condition that requires immediate medical treatment.
Accurate diagnosis of CLIDE is essential for effective management and to rule out other ocular conditions. An eye care professional can determine whether your symptoms are specifically related to contact lens use and tailor a treatment plan.
Your eye doctor will review your medical history, lens-wearing habits, and any medications you're taking. They will then evaluate the health of your ocular surface, assess the fit and condition of your contact lenses, and check for signs of inflammation or damage using special magnifying tools and lights.
Your doctor may use specific tests to measure tear quality and quantity. The Schirmer test measures tear production, while the tear breakup time (TBUT) test assesses how quickly tears evaporate. Other tests may include osmolarity measurement to check the salt content of your tears, meibomian gland evaluation, or using special dyes like fluorescein to highlight surface damage.
Your eye doctor will examine how your current lenses move on your eyes and check for proper alignment. They will assess whether the curvature and size are right for your eye shape. This helps determine if a different lens design or material would be more comfortable for you.
CLIDE can mimic other conditions such as blepharitis, allergic conjunctivitis, or corneal infections. Your doctor may recommend temporarily stopping lens wear to see if symptoms improve. If underlying health issues are identified, prompt treatment can prevent complications.
CLIDE management typically involves a combination of lifestyle modifications, lens adjustments, and medical therapies. Most patients experience significant improvement with consistent, targeted interventions.
Over-the-counter preservative-free artificial tears are often the first-line therapy, providing rapid relief. Options include:
Drops made for contact lens wearers are safe to use with your lenses in. Apply drops before inserting lenses, during wear, and after removal for maximum comfort.
Switching to daily disposable lenses can reduce the accumulation of deposits and lower inflammation risk. Your doctor might recommend newer lens materials with moisture-retaining technology, like water-gradient lenses. Using a hydrogen peroxide-based cleaning system can also help sensitive eyes by avoiding preservatives found in many multipurpose solutions.
Increasing blink frequency during screen use by following the 20-20-20 rule (every 20 minutes, look 20 feet away for 20 seconds) can help. Using a humidifier in dry environments, staying well-hydrated, and avoiding direct airflow from fans or vents can reduce tear evaporation. Wearing wraparound sunglasses outdoors protects against wind and UV rays.
For persistent cases, prescription therapies such as topical cyclosporine (Restasis) or lifitegrast (Xiidra) can reduce inflammation and promote tear production. Punctal plugs are tiny devices inserted into tear ducts to keep natural tears on the eye surface longer. In some cases, scleral lenses that vault over the cornea may be recommended.
Omega-3 fatty acid supplements from fish oil or flaxseed can improve tear quality and reduce eye inflammation when taken regularly. Some studies suggest that vitamin D supplements may also help with dry eye symptoms. Always consult with your healthcare provider before starting new supplements.

Preventive strategies are the cornerstone of long-term comfort for contact lens wearers. Adopting healthy lens habits and environmental modifications can help keep CLIDE at bay.
Always wash and dry your hands thoroughly before handling lenses. Follow the manufacturer's recommended replacement schedule and replace your lens case every three months. Never top off or reuse lens solution; use fresh solution each time you store your lenses.
Work with your eye care professional to select breathable materials like silicone hydrogel that allow maximum oxygen flow. Daily disposables are often the best choice for reducing deposit buildup. Always follow the guidance of your eye care provider when changing your lens type or care regimen.
Blink fully and frequently, especially when using digital devices. Maintain proper hydration and include foods rich in omega-3 fatty acids, such as salmon or walnuts, in your diet. Consider wearing glasses instead of lenses on days when your eyes feel particularly dry or after extended screen use.
Schedule comprehensive eye exams annually, or more frequently if you experience persistent discomfort. Your eye doctor can monitor changes in corneal health, reassess your lens fit, and recommend updates to your care routine. Early intervention can prevent CLIDE from progressing to more serious issues.
Managing CLIDE successfully allows you to continue enjoying the convenience and freedom that contact lenses provide without sacrificing comfort or eye health.
