Are the scanners from like the store dangerous to your eyes?? I was at 7-11 and the cashier laid the sacnner down and I looked at it twice this happend just about 15 minutes ago. I was just wondering cause the red light..

Postal worker shined the red light laser scanner in my eye from 2 feet away. Looked at it for a few seconds. Any permanent damage to eyes or vision?
See your eye doctor: If the red light was a laser pointer and you stared at it for milliseconds, you might be okay if it was properly labeled in 3-5 mW, it's the nonlabeled ones (green lasers) that are problematic, but this may be a good time for you to visit your eye doctor anyway to have your annual dilated exam done too, and have them check.
