No a SHIELD is best for arc eye, sorry preventing it.
Arc eye, is a form of PHOTOKERRATIS, most people are not aware it can cause PERMANENT DAMAGE, from continued exposure, as the cells around the cornea stop rebuilding after shedding, it is this shedding which then allows the sensitive part of the eye to contact the occualr cavity(eye socket) which causes the pain, the cells regrow.
It has been know to cause total and permanent blindness in extreme cases, but can certainly cause eye problems with little exposure.
The arc of light will go through shut eyes/skin, and any reflection can cause it as well, it is the same condition as SNOW BLINDNESS, also caused by sunbeds!!
