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..
Common sense says no: Look at it this way. There must be hundreds of thousands (millions?) of scanners in use in the US. Millions of workers and customers use them and sometimes must briefly look straight into them. If you owned a company making scanners, would you market a product that causes significant harm? Of course not. The scanner wouldn't be used, or you'd be sued. Your company would quickly go out of business. ...Read more

Can a projection clock damage eyes I adjust the time and I look straight into he hole to adjust time is has a red light?
Not advisable: Looking into any light for an extended period of time can damage the macula, the center part of the retina, the light sensitive tissue that lines the back of the eye & gives sight.

Check with the manufacturer. ...Read more
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.

Inflammation: Conjunctivitis is inflammation of the conjunctiva (covering on the white part of the eye). Keratitis is inflammation of the cornea (clear layer in front of the iris). Both can be caused by viruses and both can be present at the same time. The light sensitivity and blurred vision could be caused by keratitis. Anytime you have blurred vision you should see your eye doctor immediately. ...Read more
