LEDs are not inherently damaging to the eyes. You may be referencing "blue light hazard", for which evidence is neither rigorous or unequivocal.
Assuming blue light is damaging, white LEDs need not have more blue in their spectrum than other white light sources such as incandescent, fluorescent, and gas discharge. Higher color temperate LEDs with more blue in their spectrum are commonly seen though, as their efficiency numbers are a bit better than lower color temperatures.
- shmerl 8y agoI'm talking about actual usage. Extremely bright, white LEDs. They should have used softer lights.
- Zak 8y agoI'm not sure what "softer" means. You could mean a lower color temperature (less blue, more yellow), lower output, or a diffuser over the emitters. All of those are commonly used in real LED-based lighting installations.
- shmerl 8y agoI don't find it common. There was a recent comparison of photos from the past and current street lights. Current ones are way more white.
