Glasses will not cure color-blindness, much as reading glasses won’t cure farsightedness. But a true cure could someday come in the form of gene therapy to deliver functional genes to the color-responsive cells in the retina.

Colorblindness occurs when the color-related cones in the retina overlap. These cones are responsible for processing wavelengths. When overlap happens, the brain cannot accurately respond to the wavelengths, making it impossible to differentiate or even see certain colors.

There are many different types of color blindness, and they differ based on how individuals perceive color. One of the most common is dichromatism, often referred to as red-green color blindness.

We enhanced the red-green singal lens technolgy, improved significant effect.
Color glasses aren't a cure for color blindness. Once you take the glasses off, the world will look the way it did before. Some people who try the glasses experience an immediate, dramatic result.

-They really do work!
I bought these for my son who is color blind ...he was amazed at the his ability to see colors so differently than he could without them! He also passed all the color blind tests we gave him with them on!

-This product WORKS! You will not be disappointed
Bought as a present. Glasses arrived the next day. My 16 years old nephew was able to see color fornthe first time in his life. The response from his expression was priceless. Would recommend these to anyone.

-Amazing! Take a chance on these!
I got these for my boyfriend who is red-green colorblind (mild-protan). He put them on and was absolutely amazed. He never takes them off... like he literally watches TV with them. He thinks trees are amazing and the fall tree colors blast to watch him experience. If your hesitant, just get them.

The answer is that color blind glasses are transparent. They look like normal glasses, but they have filters in them that help people with red-green color blindness see better.

The most common kinds of color blindness are genetic, meaning they're passed down from parents. Color blindness can also happen because of damage to your eye or your brain. Sometimes, problems with color vision are due to a disease affecting your optic nerve, such as glaucoma. Poor color vision can also be the result of an inherited problem with the cones (color-sensitive photoreceptors) in your retina.

To ensure optimal effectiveness, wear the lens for at least 10 hours in a variety of situations over the course of 1-2 weeks.
