Pilestone Color Blind Glasses for Red-Green/Blue-Yellow Color Vision Deficiency Indoor/Outdoor Use ~ Pick Yours (Classic TP-025 Lens B for Strong Red-Green Deficiency)

Please kindly understand that colorblindness is NOT a uniform disease. Colorblindness is caused by mutations in the color-sensing transmembrane proteins located on the cone cells in your retina. This mutation might occur in different cone cells, or in different amino acid residues in a protein of the same cone cells. In other words, the disabled spectrum windows and the severance may be totally different from person to person. With all these said, please kindly spend some time selecting the lens by taking the FREE colorblind test on Pilestone Official Website by yourself or with your eye doctor. Also please be aware that our glasses are universally designed to cope with the most common conditions. Different people may have different experiences with the same pair of glasses. There is a 10-15% chance that our glasses completely don’t work even if you pick the one suggested by the test.
