Blue light is a wavelength that is present in light,
including light from the sun. Compared to other types of light, blue light has
a short wavelength. This is crucial because doctors associate short-wavelength
light with a greater chance of eye damage. Many blue light blocking glasses have been
introduced on the market to protect your eye problems. These glasses have
specially framed lenses that are said to block or filter out the blue light
given off from mobile screens or other digital screens. The lenses are often
marketed with lofty claims that they shield your eyes from eye strain and can
assist you in reducing potential damage to your retina from prolonged exposure
to blue light.
