If you get hand sanitizer in your eye, start flushing it with clean, lukewarm tap water immediately and keep flushing for at least 15 to 20 minutes. Speed matters more than anything else here. The alcohol in hand sanitizer (typically 60% to 70% ethanol or isopropanol) can damage the surface of your eye, and the severity of that damage depends largely on how quickly and thoroughly you rinse it out.
How to Flush Your Eye Right Now
Use whichever water source you can reach fastest. The Mayo Clinic recommends these options:
- Shower: Step in and aim a gentle stream of lukewarm water on your forehead, just above the affected eye. Let the water flow down over your open eye. If both eyes are affected, aim the stream at the bridge of your nose.
- Sink: Tilt your head down and to the side so the affected eye is lower. Hold your eyelids open under a gentle stream from the faucet.
- For young children: Have them lie down in the bathtub or lean back over a sink. Pour a gentle stream of water on the forehead above the affected eye.
Hold your eyelids open with your fingers throughout the rinse. Your natural reflex will be to squeeze them shut, but you need to fight that instinct. Keep flushing for a full 15 to 20 minutes, even if the stinging improves before then. The goal is to dilute and wash away all traces of the alcohol and any other chemicals in the sanitizer gel.
If you’re wearing contact lenses, don’t waste time trying to remove them before you start rinsing. Begin flushing immediately. If the lens hasn’t washed out on its own after several minutes of rinsing, try to remove it then. Discard the lenses afterward.
Why Hand Sanitizer Can Hurt Your Eyes
Hand sanitizer isn’t just mildly irritating to the eye. At concentrations above 50%, ethanol can destroy cells on the corneal surface and trigger inflammation and swelling. The cornea is covered by a thin layer of epithelial cells that protect and heal your eye, and high-concentration alcohol strips those cells away. In more serious exposures, it can also damage the stem cells that regenerate the corneal surface and affect the deeper structural layers of the cornea.
Gel-based sanitizers pose an extra risk because the thick consistency can trap the alcohol against the eye’s surface for longer, increasing the exposure time. This is one reason delayed or inadequate rinsing can turn a minor splash into a more significant chemical burn. In one published case, a patient who didn’t irrigate thoroughly developed severe eyelid swelling, extensive corneal damage, and tissue changes visible across nearly half the cornea within two hours of exposure.
What to Expect Afterward
After a brief, minor splash that you flushed right away, you’ll likely feel stinging, burning, and some redness for a few hours. Most mild cases resolve within about five days as the corneal surface regenerates. Preservative-free artificial tears can help soothe irritation during this period. Avoid redness-relief drops, which constrict blood vessels and can mask signs of a more serious injury.
More significant exposures take longer. If the alcohol causes a corneal ulcer or larger area of surface damage, the FDA reports a median healing time of about 13 days in children. In one adult case involving a gel sanitizer, both the corneal defect and surrounding tissue damage resolved in about two weeks with medical treatment.
Signs You Need Medical Attention
Some stinging and redness after flushing is normal and expected. But certain symptoms suggest the exposure caused real damage that needs professional care. Get to an eye doctor or emergency room if you notice any of the following after rinsing:
- Pain that persists or worsens over the hours after flushing, especially sharp pain or a deep ache
- Blurred or decreased vision in the affected eye
- Sensitivity to light (photophobia) that makes it hard to keep the eye open
- Significant swelling of the eyelid or the white part of the eye
- A white or cloudy patch visible on the surface of the eye
- Excessive tearing that doesn’t settle down within a few hours
If you’re unsure whether your symptoms warrant a trip to the ER, Poison Control offers free guidance. You can use the webPOISONCONTROL online tool at poison.org or call 1-800-222-1222 to speak with a specialist. Both services are free and available around the clock.
Children Are at Higher Risk
Kids are disproportionately affected by hand sanitizer eye injuries. Wall-mounted dispensers in schools and stores often sit at a child’s eye level, and a pump that squirts upward can send a stream of gel directly into the face. Children also have a harder time keeping their eyes open during flushing, which makes adequate irrigation more difficult.
If your child gets sanitizer in their eye, lay them down in the bathtub with their head tilted so the affected eye is lower. Pour water gently across the forehead and into the open eye. Try to keep them calm and their eyelids open for the full 15 to 20 minutes. Research on pediatric cases consistently finds that the severity of the injury correlates with how much gel entered the eye and how quickly and thoroughly it was rinsed out. Poor or delayed irrigation is the single biggest factor that turns a minor exposure into a serious one.
Resist the urge to let a child rub the affected eye afterward. Rubbing can scratch the already-compromised corneal surface and create a secondary abrasion on top of the chemical irritation.
Preventing Future Exposures
Apply hand sanitizer to your own palm first, then rub your hands together and let them dry before touching your face. If you’re dispensing sanitizer for a child, put it on your hand and then apply it to theirs, keeping the nozzle pointed away from their face. Watch for wall-mounted dispensers in public spaces that sit at a child’s head height, and position your child to the side when using them.
