What Is Harmful Blue Light?
It’s part of the visible light spectrum, which comes from both the sun and artificial light sources like digital screens and fluorescent lights.

What are the advantages and disadvantages of polycarbonate spectacle lenses?
Polycarbonate lenses are made by injection moulding. These lenses have good impact resistance and therefore are ideal for children, sports and industrial purposes. It also has good UV protection and a higher refractive index than CR39. The disadvantages of polycarbonate lenses include the fact that their abrasion resistance is poor, but when an anti scratch coating is added to this the impact resistance is reduced slightly. These types of lenses cannot be tinted easily.
