Lasers are cutting edge. They’re used in all kinds of products -- from music players and printers, to surgical tools.

But use of lasers in toys has the FDA worried and, as a parent and a physician, I share their concern.

There are lasers on toy guns to help you aim, tops with lasers that project a beam as they spin, and toy light sabers with lasers for beams.

Then there are mom’s or dad’s laser pointer or keychain which can be easily snatched to use as a toy.

Lasers can be dangerous. Pointed in the wrong place, they can cause serious eye injuries, including blindness. It may only takes a second, and then it’s too late.

The really scary part is eye damage may not be obvious immediately, then can get worse over time, and lead to permanent harm.

Never point a laser at a person or an animal. And don’t shine it at a reflective surface. The beam can bounce back and harm you.

And parents: think carefully about buying a laser-containing toy.
