Why Do My Eyes Burn When Wearing Contacts Possible Lens Or Solution Issues

Burning eyes while wearing contact lenses is more than just a minor annoyance—it can signal underlying problems with your lenses, care routine, or even your ocular health. While occasional dryness or irritation might seem normal, persistent burning sensations should never be ignored. The root causes often lie in lens material, cleaning solutions, environmental factors, or improper wear habits. Understanding these triggers empowers you to take control of your comfort and eye safety.

Contact lenses sit directly on the cornea, making them highly sensitive to chemical imbalances, debris buildup, and oxygen flow disruptions. When something goes wrong—whether it’s a reaction to preservatives in solution or a microscopic tear in the lens—the result can be stinging, redness, or a persistent burning feeling. This article breaks down the most common reasons for this discomfort, identifies key warning signs, and provides practical strategies to resolve and prevent recurrence.

Lens-Related Causes of Burning Sensations

The physical properties of your contact lenses play a major role in how comfortable they feel throughout the day. Certain materials, designs, or conditions can contribute to irritation and burning.

• Low Oxygen Permeability: Some older or poorly designed lenses restrict oxygen flow to the cornea. When the eye doesn’t receive enough oxygen (a condition known as hypoxia), it becomes irritated, leading to a burning sensation, especially after several hours of wear.
• Lens Deposits: Proteins, lipids, and other debris from your tears accumulate on lenses over time. Even with regular cleaning, residue can build up and create a rough surface that irritates the eye.
• Damaged or Worn-Out Lenses: Microscopic nicks, tears, or warping alter the lens’s surface smoothness. These imperfections can scratch the cornea or trap irritants, causing immediate burning upon insertion.
• Poor Fit: If your lenses are too tight or too loose, they may rub against the conjunctiva or fail to center properly, increasing friction and discomfort.

Tip: Replace lenses according to your optometrist's schedule—even if they look intact. Overwearing lenses is a leading cause of chronic irritation.

Solution Sensitivities and Chemical Irritation

Your contact lens solution is meant to clean, disinfect, and store your lenses safely—but not all solutions are compatible with every wearer. Some ingredients commonly found in multipurpose solutions can trigger adverse reactions.

Preservatives like thimerosal, polyhexanide, or chlorine donors help prevent microbial growth but may cause allergic responses or toxic keratoconjunctivitis in sensitive individuals. Symptoms include burning, itching, redness, and excessive tearing shortly after inserting lenses.

Additionally, failing to rinse lenses thoroughly after soaking can leave behind residual solution chemicals. This is particularly problematic with non-rinse solutions used incorrectly. Some people also experience discomfort when switching between solution brands without proper adaptation.

“Up to 20% of contact lens wearers report sensitivity to certain solution components. A switch to preservative-free or hydrogen peroxide-based systems often resolves unexplained burning.” — Dr. Lena Torres, Optometrist and Corneal Specialist

Common Solution Ingredients That May Cause Irritation

Ingredient	Purpose	Potential Risk
Polyquaternium-1	Disinfectant	Mild stinging in sensitive users
Chlorhexidine	Antimicrobial agent	Allergic reactions, corneal toxicity
EDTA	Chelating agent (binds metals)	Can enhance penetration of other irritants
Hydrogen Peroxide	Powerful disinfectant	Severe burning if not fully neutralized

If you're using a hydrogen peroxide system, ensure the lens case has a complete neutralization cycle (typically 6–8 hours) before wearing. Inserting lenses too soon exposes your eyes to active peroxide, which causes intense burning and potential corneal damage.

Environmental and Lifestyle Triggers

External factors significantly influence how your eyes react to contact lenses. Even high-quality lenses and solutions can't compensate for harsh environments.

• Dry Air: Indoor heating, air conditioning, and low humidity reduce tear film stability. This leads to evaporative dry eye, where the surface of the eye dries out faster than it can replenish, resulting in a burning sensation.
• Screen Use: Prolonged focus on digital screens reduces blink rate by up to 60%. Less blinking means fewer tears spread across the eye, increasing friction between the lens and cornea.
• Smoke and Pollutants: Cigarette smoke, smog, and volatile organic compounds (VOCs) from cleaning products can adhere to lens surfaces and trigger inflammation.
• Allergens: Pollen, pet dander, and dust mites may bind to lenses, creating a constant allergen load on the eye surface, especially during allergy season.

Tip: Use a humidifier at work or home if you frequently experience dry, burning eyes—especially in winter months.

Step-by-Step Guide to Diagnosing and Resolving Burning Eyes

Follow this structured approach to identify and eliminate the source of discomfort:

1. Remove lenses immediately when burning occurs. Do not continue wearing them, as this may worsen irritation or lead to infection.
2. Rinse eyes gently with sterile saline solution to flush out any chemical residues or allergens.
3. Inspect lenses carefully under bright light for scratches, deposits, or deformities. Discard any damaged lenses.
4. Clean your lens case thoroughly with hot water and let it air-dry. Replace cases every 1–2 months to prevent biofilm buildup.
5. Switch to daily disposables temporarily to rule out solution or deposit-related issues. Since there’s no reuse or cleaning involved, this helps isolate the problem.
6. Try a preservative-free saline or peroxide-based solution if continuing with reusable lenses.
7. Schedule an eye exam if symptoms persist beyond 24 hours or recur regularly. An optometrist can assess corneal health, fit accuracy, and tear quality.

This process systematically eliminates variables, helping determine whether the issue stems from hygiene, product choice, or physiological factors.

Mini Case Study: Sarah’s Reaction to Multipurpose Solution

Sarah, a 29-year-old graphic designer, began experiencing sharp burning in both eyes within minutes of inserting her bi-weekly silicone hydrogel lenses. She had worn the same brand for two years without issues but recently switched to a new multipurpose solution marketed as “gentle” and “moisturizing.”

Initially, she assumed it was due to long screen hours. She tried artificial tears and reduced her computer use, but the burning persisted. After removing her lenses and switching back to saline rinsing followed by her old solution, the discomfort disappeared. Upon consulting her optometrist, she learned she had developed a sensitivity to polyquaternium-1, a disinfectant in the new solution.

The doctor recommended a hydrogen peroxide-based system with a neutralizing disc. Within days, Sarah reported complete relief. Her case highlights how seemingly harmless changes in care routines can trigger significant reactions—even with products labeled as safe.

Checklist: Preventing Contact Lens-Induced Eye Burning

Use this checklist to maintain optimal lens comfort and eye health:

• ✔ Replace lenses on schedule (daily, bi-weekly, monthly)
• ✔ Wash hands before handling lenses
• ✔ Never top off old solution—always use fresh solution each time
• ✔ Replace lens case every 60 days
• ✔ Avoid tap water exposure (risk of Acanthamoeba keratitis)
• ✔ Remove lenses before swimming or showering
• ✔ Use rewetting drops approved for your lens type
• ✔ Attend annual eye exams to reassess fit and eye health
• ✔ Consider daily disposables if you have recurrent irritation
• ✔ Keep a symptom journal if burning recurs (note timing, products used, environment)

Frequently Asked Questions

Can allergies cause my eyes to burn when wearing contacts?

Yes. Allergies increase histamine release in the eye, leading to itching, redness, and burning. Contacts can trap allergens against the eye surface, worsening symptoms. Using daily disposables during allergy season and applying antihistamine eye drops (as directed by a doctor) can help.

Is it safe to sleep in my contacts if they’re approved for extended wear?

Even lenses labeled for overnight wear carry increased risks of hypoxia, microbial infection, and irritation. Sleeping in contacts reduces oxygen flow and raises the chance of corneal swelling and bacterial adhesion. Unless absolutely necessary and under medical supervision, avoid sleeping in lenses.

Why do my eyes burn only in the evening?

Evening burning is often linked to dry eye syndrome exacerbated by prolonged screen use, indoor air conditions, or end-of-day lens dehydration. It may also indicate protein buildup on reusable lenses. Try using lubricating drops during the day and consider switching to daily disposables.

Protect Your Vision with Informed Choices

Burning eyes while wearing contacts aren’t something you should simply endure. They serve as a warning sign that something in your lens-wearing routine needs attention. Whether it’s a mismatched solution, poor hygiene, environmental stress, or an underlying eye condition, identifying the cause early prevents complications like corneal abrasions, infections, or chronic dry eye.

The best defense is proactive care: stick to replacement schedules, choose hypoallergenic solutions when needed, maintain strict hygiene, and listen to your body’s signals. When in doubt, consult your eye care professional rather than self-diagnosing. Your vision is too valuable to compromise for convenience.
