What is best to put on your eyes for wielders flash? my son dropped his wielders helmet while wielding last night...

If : If the eyes feel fine---nothing needs to be done. If he is in pain, he needs to see an ophthalmologist to treat the burn to the cornea which should heal up fine.

Welders : Welders flash is a series of very fine, micro-scratches on the cornea, which is the front surface of the eye. It is caused by ultraviolet light exposure during arc welding. Patients usually have pain, tearing, redness and light sensitivity. Artificial tears (the thicker the better, consider a gel) are very helpful in easing symptoms, but if the eyes don't clear within 12 hours or so, you should have your son see an ophthalmologist for antibiotic drops or ointments. Occasionally, patients need to be patched for faster healing. Retina toxicity is very rare in this circumstance, and with this brief exposure it is very unlikely to be an issue.

Welder's : Welder's flash or welding arc can cause damage to the retina in the back of the eye. This injury is similar to the damage caused by staring at the sun for a while. If the exposure was for a short period, the vision often returns. However, if the exposure was for a prolonged time, then the vision may return only partially. It is always advisable to use the welders helmet. If there is a decreased vision, have it evaluated by an ophthalmologist.
