Why didn’t my test results improve when I took the test while wearing the glasses?

Your results on the Ishihara test or even the EnChroma color blindness test are not expected to "improve" when wearing our glasses. Re-taking the test wearing EnChroma glasses is not to be used as a diagnostic of the glasses' performance.

A better measure of success is if you are noticing changes in the colors of the world you see while wearing EnChroma glasses. If so, they are likely working for you! The glasses do work for about 80% of the people with red-green color vision deficiencies who try them. Our customers also report that in most cases, their experiences get better over time.
