Why Do Contact Lenses Sting Your Eyes? Causes, Warning Signs, and Care Tips

Stinging eyes after wearing contact lenses is a common concern. It may happen immediately after inserting the lenses or occur with irritation, red eyes, or blurred vision. Possible causes include dry eyes, dirt on the lenses, or wearing contact lenses incorrectly. If left unaddressed, these symptoms may worsen and affect long-term eye health.

In this article, Better Vision explains the possible causes of burning or stinging eyes while wearing contact lenses, along with signs to watch for and practical care tips for safer, more comfortable wear.

Key Takeaways

• Stinging eyes while wearing contact lenses may result from dry eyes, deposits or dirt on the lenses, wearing lenses for too long, or choosing lenses that do not suit your eyes. Do not continue wearing lenses when you experience unusual symptoms.
• Blurred vision after sleeping in contact lenses is a warning sign not to ignore. Sleeping in lenses—especially lenses not designed for overnight wear—may increase the risk of irritation and infection.
• Contact lenses should not be worn continuously for long periods. Give your eyes a break by alternating with glasses on some days to reduce the risk of dry eyes, burning, and irritation.
• If you experience blurred vision, red eyes, or irritation after removing your lenses, stop using them immediately and see an ophthalmologist if symptoms do not improve.
• Regular eye examinations and contact lenses that suit your prescription can help improve comfort and reduce the risk of stinging eyes.

What Causes Stinging Eyes While Wearing Contact Lenses?

Stinging eyes while wearing contact lenses can result from several factors. Identifying the underlying cause can help address the problem and reduce the likelihood of it happening again.

• Dry eyes: When the eyes do not produce enough tears, contact lenses may cause irritation and stinging. This is especially common among people who use computers or spend long periods in air-conditioned rooms.
• Unclean lens solution or sensitivity to lens solution: Expired or contaminated solution—or ingredients that do not suit your eyes—may cause stinging after inserting contact lenses.
• Worn, damaged, or expired lenses: These may rub against the cornea, causing irritation, discomfort, or blurred vision.
• Wearing lenses for too long: Wearing contact lenses continuously for many hours or sleeping in them can reduce the oxygen reaching the eyes, leading to stinging and red eyes.
• Conjunctivitis: An infection may cause red eyes, stinging, irritation, or unusual eye discharge while wearing contact lenses.
• Dust or foreign matter on the lens: This may cause a sharp stinging sensation, as though chilli has entered your eye. Remove the lenses, clean them, or replace them before wearing lenses again.

When Should You Remove Your Contact Lenses Immediately?

Stinging eyes may sometimes be caused by mild irritation. However, if you experience other unusual symptoms as well, do not continue wearing your lenses, as this may affect your eye health.

• Severe stinging that makes it difficult to open your eyes: If it feels as though something sharp is scratching your eye, stop wearing the lenses, as the cornea may be irritated.
• Severe or persistent red eyes: If irritation, redness, or excessive tearing does not improve after removing your lenses, stop using them immediately.
• Blurred vision: If your vision remains blurry after blinking several times, the lens may have shifted, your prescription may be unsuitable, or there may be an eye concern that needs attention.
• Persistent irritation or irritation in one eye: There may be dust, an eyelash, or lens damage. Remove the lens and inspect it before further use.
• Eye pain with light sensitivity or unusual discharge: If you have eye pain, pain when looking at light, or yellow or green discharge, stop wearing contact lenses.
• Headache with visual disturbance: If wearing contact lenses causes headaches together with blurred vision or dizziness, remove them first, as your prescription may not be suitable.

If your eyes still sting after removing your lenses—or you have severe symptoms such as eye pain, significant redness, blurred vision, or light sensitivity—see an ophthalmologist promptly to identify the cause and receive appropriate treatment.

How to Clean Contact Lenses Properly

Proper lens hygiene can help reduce the risk of stinging eyes while wearing contact lenses. If you frequently experience discomfort even with correct cleaning, arrange an eye examination and consult an optometrist to assess whether your current lenses still suit your eyes.

• Wash your hands with soap and dry them thoroughly before touching contact lenses to reduce contamination.
• Use only contact lens solution specifically designed for cleaning and storing lenses. Do not rinse or store lenses in tap water or plain water, as this may increase the risk of infection.
• Use fresh lens solution every time and clean the lens case regularly. Do not top up old solution with new solution.
• Replace contact lenses according to their recommended replacement schedule. Do not wear lenses beyond their intended lifespan, as they may cause stinging or discomfort.
• Avoid sleeping in contact lenses, as it reduces the oxygen reaching the eyes and increases the risk of irritation and infection.

How to Choose Contact Lenses That Suit Your Eyes

Contact lenses are prescription lenses worn directly on the surface of the eye. Choosing lenses that suit your needs and using them correctly can reduce the risk of stinging, irritation, and unclear vision.

• Choose the right lens type: Select daily, monthly, or specialised prescription lenses according to your visual needs and the care routine you can follow.
• Choose the correct prescription: Have your eyes examined regularly before changing lenses. An unsuitable prescription may cause blurred vision, headaches, or poor visual clarity.
• Choose the right lens diameter and base curve: Lenses that do not fit properly may shift or fail to stay centred, causing discomfort during the day.
• Choose a material that suits your eyes: People with dry eyes may benefit from lenses that retain moisture and allow sufficient oxygen transmission to the cornea.
• Choose certified products and do not wear lenses beyond their replacement period: This helps reduce the risk of irritation, infection, and red eyes.
• Consult a professional before your first pair or when changing lens types: This helps ensure that the lenses suit your prescription and eye characteristics.
