Hi. Most likely there's absolutely no damage to the retina here but just to be certain he should have an eye exam from an optometrist as soon as possible.
Most of those lasers don't cause damage
Let me know if you need any more information please
Hi, I have looked closer at the laser and it says 500mw on it - and my son assures me that he flashed it in his eye for a second or less.
That's a medium power laser but if it only flashed on his retina for a second then there shouldn't be any harm done Muriel.
But still it would be best to have an optometrist take a look at his retina
