ABSTRACT:
The invention provides contact lenses that substantially block either or both UV and blue light from entering the lens wearer's pupil by providing multiple concentric areas of certain materials that decrease or substantially eliminate the UV and blue light transmission. The lenses of the invention accomplish the light blocking without degrading the lens wearer's vision.
