The high quality Lemon yellow coloured filter clip-ons are worn on top of normal spectacles and can be flipped up as required. Filters absorb the short wave, high-energy ultraviolet and blue elements of the light so enhancing contrast and reducing photosensitivity. The lemon yellow filter has a good absorption rate for UV elements of light and allows a good transmission of light through the filter. Providing heightened contrast, maximum brightness and enhanced visual acuity the yellow tint is particularly suited for Macular Degeneration, Optic Atrophy, Albinism and Pseudophacia.
