Blue cut

The function of Blue Cut lenses is to reduce the effects of blue light. Blue Cut Premium 35 absorbs 35% of the blue light – between the 420nm and 450nm wavelenght. Blue Cut Hi-tech 50 absorbs 50% of the blue light – between the 420nm and 450nm wavelenght. Both absorb 100% of ultraviolet light, protecting the eye and making the use of electronic devices less inconvenient.
