Color Blindness

Color blindness is a deficiency in the way one sees color. Patients with this problem have difficulty in distinguishing certain colors, such as blue and yellow or red and green. Delmon Optic offers special lenses combined with filters to enhance color perception and increase the color spectrum perceived by the patient. Corrective filtered lenses are also provided to albino patients who suffer from high light levels.
