What is blue light?

Blue light is, in fact, the harmful rays that emit especially from the digital screens such as a computer, laptops, tablets and game stations that people use a lot in daily life. So we need blue light filter lenses.





In fact, studies show overexposure to blue light may be linked to eye strain, increased risk of macular degeneration, and sleep cycle disruption. One of the ways that you can reduce your exposure to blue light is by wearing glasses with blue light blocking lenses.
