I rubbed some pimple cream in my eyes by accident. How will I stop it stinging?

Wash immediately. Dilute with eye wash. If symptoms persist see opthamologist for prescription eye drops.
Wash out eye. You must flush the eye immediately with an eye wash if you have, or tap water. Then see an ophthalmologist if any symptoms persist such as tearing, burning or pain, to ensure that your cornea has not gotten burned. Don't rub the eye.
