“Can I wear blue light blocking glasses all day?”

It will not hurt your eyes to wear blue light blocking glasses.

Yes. No issues with damage to the eye if you wear them even for a prolonged period of time.

This is an excellent question and a somewhat controversial subject. Remember ROY G BIV from high school science class? Visible light is made up of various wavelengths from Red (low energy) to Violet (high energy). "Blue" light is unfortunately used to describe the "High Energy" wavelengths from blue to violet. The violet light has the highest energy and is probably the most damaging to structures inside the eye from long-term exposure. Macular degeneration, where the retina (film in the camera) goes bad may be impacted by long-term exposure to violet light. Computer and cell phone screens do emit light in the blue to violet spectrum. By filtering out some of this light, as with blue blocking glasses, the eye has an easier time focussing and, thus, may lead to reduced eye strain. Blue light, on the other hand, is important for dim light vision and for maintaining circadian rhythms so we don't want to completely filter blue light out the entire day!

No problem at all

Yes, it's okay to wear it all the time.
