It will not lead to blindness but will do harm to your eyes. Actually, the hand sanitizer is a kind of an alcohol based gel that kills viruses and bacteria when applied to the hands. Most hand sanitizer products contain a least 60 percent alcohol, usually ethanol or isopropanol, which is what makes then so effective against viruses and bacteria. However, it the hand sanitizer accidently get into your eyes, it burns and irritates. If you get hand sanitizer in your eyes, your immediate goal is to dilute, then remove the alcohol. The antidote is copious amounts of lukewarm water: pour as much as possible across the surface of your eye for 10 to 15 minutes. Make sure the water's not too hot or too cold; it should feel comfortable on your eyes. The water needs to thoroughly rinse the surface of your eye. It also needs to remove traces of alcohol from the mucous membranes inside your eyelids, so blink rapidly while pouring the water across your eye. If the sanitizer is in only one eye, be careful not to contaminate the other eye. Keep the uninjured eye tightly closed, and tilt your head so the injured eye is downward.If your eyes are still red, irritated or burning after treatment, consult your physician.
These hand cleaners contain a mixture of alcohol, water and a thickening agent to help the solution spread completely over the hands. Some solutions may contain moisturizers, perfumes or other non-medical additives. And we know that alcohol is ethanol. During the production of ethanol, methanol may be produced as side reactions. If ethanol and methanol in hand sanitizer gets into eyes, it may cause blindness. If you get hand sanitizer in your eye, wash your eyes continuously for at least 15 minutes with fresh water, take the bottle of sanitizer and immediately go to your doctor or to the ER without any hesitation.
But if the hand sanitizer you use are of non-harmful chemicals, it won't cause blindness.
It is really so bad for you to get the hand sanitizer into the eyes. The disinfect role in the hand sanitizer will make you look so damaged at the eyes. You should wash it out of the eyes quickly with the clean water. Then you could use the clean cloth to dry the eyes. Then you may use the warm compress to make your eyes feel comfortable.
