Can LED light bulbs harm your eyes?
I was reading about blue light hazard. are they safe?

Small LED's do not harm eyes. A large blue light can do damage, whatever it says in the reading. You may be talking Xenon, not LED, whatever, too much candlepower burns our retinae.

Only if you like directly stare at it for some time than it is harmful but otherwise no.

Well, really any light bulb can harm your eyes if you stare at it long enough.

But yes. They are safe to take a quick glance for 5 seconds. They won't burn a hole or anything.

Jack B
They won't directly damage your eyes , but , you shouldn't put that kind of a strain on your vision . You need to use good lighting to read .

only if you inject oxycodone otherwise stare away

Yes, in sufficient power, any light, at any spectrum on the visible, and some of the invisible light spectrum, can cause harm at long exposure rates, or high powers.

The blue light hazard is being examined and I guess we wait to see the results. Not much choice really.

Leds are very low powered and the only danger I see in them would be laser light pointers, which can burn your retina.

Common sense says if it hurts your eyes to look at it, don't! And, never, ever, ever, look into a laser light pointer, or any kind of highly focused light beam. All common sense.

It seems the blue LEDS are particularly bright, to the point of annoying..But not actually harmful in daily use.. Don't go shining blue or white flashlights in your eyes..NO good..
