Please kindly understand that colorblindness is NOT a uniform disease. Our glasses are universally designed to cope with the most common conditions. Different people may have different experiences on 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.
