What is the "Blue color light "of digital devises which is said to be the cause of glares, flickers: the shorter the wave length of the light is the more energy it has. The lights with shorter wave length, like ultraviolet rays are said to cause damage to the eyes.
Blue color light are lights in the range of visible rays with high frequency. They are lights in-between 380nm to 530nm. (violet to blue lights)
They are worried that they may cause damage to the eyes since they have very short wave length like as ultraviolet rays.

3)   What is the difference between HC, HMC and SHC?

       Hard coating     AR coating/Hard multi coating        Super hydrophobic coating
makes the uncoated lens hard and increases the abrasion resistance increases the transmittance of the lens and reduces surface reflections makes the lens waterproof, antistatic, anti slip and oil resistance
