    What are the dangers of blue light?

     Blue light causes the gradual oxdation and deterioration of     
  the retina over your lifetime,leaving our eyes exposed and 
  susceptible to developing macular degeneration.

     Blue cut Lenses provide a protective shield to such harmful            lights and visual troubles by bolcking the transmission of blue light    of 400~500nm wavelength..
 
   What are the sources of blue light?

        Nowdays, everybody encounters blue light in daily
    activies.
        Fluorescent lighting, electronic screens (photos,                  computers, TVs, etc. ), and the sun emit damaging high-          energy blue light.
