A comparative study of low-vision patients: Their ocular disease and preference for one specific series of light...

One hundred low-vision patients who complained of sensitivity to light were permitted to select any one of five filters (Recreational Innovations Co.) The results show that patients with certain types of pathology prefer to use specific filters to control the light reaching their eyes. Patients with albinism chose amber filters. Patients with glaucoma of diabetes both selected the same filter. Most patients with retinitis pigmentosa found most help from a filter which allowed only 2% light transmission.
