Contact Lens Solution Irritation: Causes and Fixes

Quick answer

Contact lens solution irritation usually comes from a preservative sensitivity, an expired product, or a lens that isn't clean. Switch to a preservative-free solution, clean your lens case regularly, and if burning persists, stop wearing lenses and see an eye doctor.

You put in your lenses, and within minutes your eyes are burning, watering, or turning red. It's uncomfortable and worrying, but you're not alone. Many lens wearers experience solution-related irritation at some point.

The good news is that most cases are easy to fix once you identify the culprit. In this article, we'll walk you through the common symptoms, likely causes, and step-by-step actions to get your eyes comfortable again.

Symptoms of Contact Lens Solution Irritation

Contact lens solution irritation can show up in several ways. The most common symptom is a burning or stinging sensation immediately after inserting your lenses. You might also notice redness, excessive tearing, or a feeling that something is in your eye.

Some people experience blurred vision or mild swelling of the eyelids. These symptoms can appear right away or build up over a few minutes. If you feel any of these, remove your lenses first and assess the situation before trying anything else.

• Burning or stinging
• Redness or bloodshot eyes
• Excessive tearing
• Blurred vision
• Sensation of something in the eye

Likely Causes of Lens Solution Burning

The most frequent cause is a sensitivity or allergy to preservatives in multipurpose solutions, such as thimerosal or benzalkonium chloride. These ingredients help keep the solution sterile but can irritate some eyes, especially with prolonged use.

Another common culprit is using an expired solution or one that has been left open too long. Over time, the solution's pH can shift, and preservatives can break down, leading to stinging. Also, if you don't rub and rinse your lenses properly, residual debris or protein deposits can react with the fresh solution and cause discomfort.

Sometimes the problem isn't the solution itself but your lens case. A dirty case can harbor bacteria or old solution residue that contaminates your lenses. Finally, if you're using a solution that isn't compatible with your lens material, that can also trigger irritation.

• Preservative sensitivity or allergy
• Expired or old solution
• Improper lens cleaning
• Dirty lens case
• Incompatible solution type

What to Do Right Now: Immediate Steps

If your eyes start burning after inserting lenses, don't wait it out. Remove the lenses immediately and rinse your eyes with sterile saline or a rewetting drop designed for contact lenses. Do not use tap water; it's not sterile and can introduce harmful microorganisms.

Inspect your lenses for any visible debris or damage. If they look clean, try rinsing them thoroughly with fresh solution and reinserting. If the burning returns, stop and move to the next steps. Never 'tough it out' – prolonged irritation can lead to corneal abrasions or infections.

• Remove lenses immediately
• Rinse eyes with sterile saline or rewetting drops
• Inspect lenses for debris or damage
• If burning persists, do not reinsert

Long-Term Fixes: How to Prevent Recurrence

Once you've dealt with the immediate discomfort, it's time to figure out the root cause. If you suspect a preservative sensitivity, switch to a preservative-free solution, often labeled as 'peroxide-based' or 'for sensitive eyes.' These come in single-use vials or special cases that neutralize the solution during the disinfection cycle.

Also, review your lens care habits. Always wash your hands before handling lenses, rub and rinse each lens after removal, and use fresh solution every time you store them. Never top off old solution. Clean your lens case daily with solution (not water) and let it air dry. Replace the case every three months or sooner if it looks dirty.

If you wear colored or special-effect lenses, check whether they are prescribed for your eyes. Some costume lenses, like sclera or SFX lenses, may have different care requirements. Always follow the manufacturer's instructions and use only solution recommended for your lens type.

• Switch to preservative-free solution if you have sensitivities
• Rub and rinse lenses each time
• Use fresh solution – never top off
• Clean and air-dry your lens case daily
• Replace lens case every 3 months

Diagnosis: Is It the Solution or Something Else?

• Symptom: Burning, stinging, redness, or tearing immediately after inserting lenses. Remove lenses first and rinse eyes with sterile saline.
• Likely cause: Preservative sensitivity, expired solution, dirty lens case, or improper cleaning. Review your solution type and lens care routine.
• Corrective action: Switch to a preservative-free solution, clean your case daily, and always use fresh solution. If symptoms resolve, you've found the fix.
• When to stop and choose another option: If burning persists after switching solutions and improving hygiene, or if you experience pain, light sensitivity, or vision changes. Stop wearing lenses and see an eye doctor immediately.
