    • ANSWER:
      Too much exposure to blue light can damage retinal cells, but I don't think there are any studies that have actually tested the exact kinds of lights you're talking about with actual people's eyes (for obvious reasons).

      Just to be safe, you might want to switch to some other color, or mixed colors, or not have them on all the time.

    What happens if you stare at a UV LED light to long?
    I have heard rumors it can damage your eyes but I can still see perfectly after many times looking at it. If it's true, how does it damage your eyes?

    • ANSWER:
      It is slightly harmful to your eyes, (excessive exposure can lead to cataract later in life. But we're talking YEARS of this stuff) and if you stare for a while the image will get burned into your retinas for a few minuets, but will eventually dissipate. All in all, there is no serious damage if you're just staring for a few minuets.

    Does the lambertian radiation pattern of LEDs make them more dangerous to look at?
    Besides the potential blue light hazard of blue, white or green LEDs, does the lambertian radiation pattern of LED light make it more dangerous to look at? Unlike incandescent bulbs and fluorescents, LEDs emit light in the lambertian pattern. While looking at any strong light for long enough can be dangerous, can the lambertian pattern make LED light more dangerous, if you look directly at the source?

    • ANSWER:
      I have always advocated a shade or indirect lighting (no naked bulb/source) - particularly in the workplace - but LEDs are now a highly popular choice for torches, keyring lights, as well as downlighters under kitchen cupboards, bicycle lights and so on - mostly not looked at directly, & in any event the sun is likely the most dangerous light source to look directly at, followed by things as bright as a welding torch/oxyacetylene lamp [and megaton nuclear weapon explosions], followed by floodlights, then headlights and tweaked LEDs somewhere around this level - There's a channel mixer for microphones and the like with a very bright blue LED, painful to look at directly, so I know what you mean - but if you can look directly at something bright without an involuntary squint and a real sense of pain in the eyes and surrounding area, then it's probably not doing any harm or any damage is not lasting - used to be most things bright enough to cause ocular damage cannot be sustained without consuming a lot of power..., so at least there's a silver lining :)
