The result: more accurate color perception because the brain can now better distinguish red wavelengths from green wavelengths. To compensate for this abnormal cone response, color blind glasses contain proprietary optical materials that filter specific wavelengths of light where this overlap occurs. The abnormal overlap of sensitivity to these wavelengths results in red-green color blindness, which is the most common type of color vision deficiency. This problem most often affects cone cells that normally are sensitive to either red or green wavelengths of light. Cone photoreceptor cells make color vision possible.Īccording to Enchroma (a leading manufacturer of color blind glasses see below), most color vision deficiencies are caused by an abnormal overlapping response to light by different types of cone cells. There are two types of these cells: rods and cones. The retina contains specialized cells called photoreceptors that respond to light. Oversized color blind glasses are available that can be worn over prescription eyeglasses.Ĭolor vision begins in the retina in the back of the eye. They also can be worn over contact lenses if you need vision correction.

These are the ones to buy if you don't have vision problems (other than color blindness) and have 20/20 visual acuity without corrective lenses. Color blind glasses with non-prescription lenses are less expensive than prescription colorblind glasses. If you need vision correction for nearsightedness, farsightedness or astigmatism, color blind glasses can be made to your custom eyeglass prescription. Though most types of colorblind glasses look like sunglasses, they are available with different kinds of lenses: Types of colorblind glassesĬolorblind glasses come in different tints, based on the type and severity of color blindness you have. But they enhance and partially correct certain color vision deficiencies of colorblind individuals. Color blind (or colorblind) glasses do not cure color blindness or produce 100% normal color vision. Color blind glasses are eyeglasses with specially tinted lenses that help a colorblind person see colors more accurately.
