Anyone know about lazer’s and will it have left any trace on my eyes, any damage?
Was he using the laser to scan a barcode or cut the parcel in half?
Lasers must be CE certified and comply with EN60825-1:2007 in order to be legally placed on the market in the EU. You could check the scanner for a CE mark and request a copy of the Deceleration of Conformity from the manufacturer. This should be publicly available.
In the event of a potential claim where you can prove partial loss of vision your legal team can request sight of the technical construction file to verify the claims in the DoC.
However, if he was scanning, not cutting*, it’s likely a Class 2M laser, in which case you are protected by your natural blink aversion, unless you were using an optical instrument to look into the beam (magnifying glass, microscope, binoculars). Or you had matchsticks in your eyes.
Since I suspect you weren’t using binoculars and probably blinked, I’d recommend you MTFU.
* If he was cutting, it’ll be a Class 4 laser but should be in a sealed room and protected by interlocks.
