What are the signs of damaged vision if i accidentally looked at a laser point?

Tiny blind spot: If the laser beam you glanced at was of sufficient power to cause damage, it would burn the light receptors in it s path, destroying the ability to see at that point. You would notice with the eye that got exposed, a tiny blind spot. This would gradually fade from your consciousness over time as the other eye would see at that point but you could always find it from the affected eye.
