scratched lens on your eye can heal itself in a few minutes time. just keep the eye closed and dont rub it. only reason to goto a doctor is if u totally scratch the eyeball into tiny bits and pieces.
its been almost a day.. ive got insurance so it'll only cost alittle bit to go get it checked. If its something bigger than its worth it to get it checked instead of going blind :P
i will take your tip of keeping it closed though. Ive been trying to keep it open thinking it just needs some air.. but it does make more sense of keeping it closed ^.^
eyes dont need air at all. in fact they are always covered in a layer of tears to protect them from the air. this layer of tears is replenished every time you blink.
