Specially enhanced lenses are effective glasses for color blindness. These lenses are most effective at correcting red and green imperfections. Glasses for color blindness are not effective at correcting the inability to see blue and yellow, but some patients will see adequate improvement with use. Glasses cannot permanently improve color blindness, but they do work to change the eye’s ability to perceive different colors.
Color blindness is considered a genetic disorder, so regular prescription eyeglasses are ineffective. In the late 1990s, special colored lenses were developed to help people suffering from color deficiency of red and green. These glasses for color blind contacts are effective at bringing out the shades of red and green. It also brightens shades that color-blind individuals would normally see dim.
Some people may not find effective glasses for color blindness.
Since most people with color blindness cannot distinguish between red and green, the few who cannot distinguish between yellow and blue will benefit little from these types of lenses. In extreme cases where you can only see shades of black, gray and white, you won’t benefit from glasses for color blindness.
It is important for patients to be aware that glasses for color blindness do not achieve 100% normal vision. This lens increases the difference between different shades. People who are colorblind are more likely to see enhanced versions of colors that are difficult to distinguish.
To be as effective as possible, wear only one special strengthening lens. This allows the brain to process the fact that the eye is actually seeing distinct colors. The same level of color blindness is maintained when both eyes look at a specially enhanced lens of the same hue. Some people choose to use two lenses, but each one has a separate tint, which has proven to be just as effective as using a single tint lens.
Wearing color-blind glasses tends to improve only in certain areas.
Other aspects of a patient’s vision may be impaired from use. For example, you can’t wear lenses while driving because most of them impair your ability to judge distance in low light conditions. Fluorescent and stereoscopic effects can also be seen when using the lens.
