Colorblindness (Daltonism) is usually a congenital disease. The cause of colorblindness is the lack of certain substances in the eye. As it may arise from hereditary causes, it may also occur as a result of some eye diseases such as visual acuity, visual point and eye pressure.

Previously inherited hereditary colorblindness could not be cured. However, congenital colorblindness can also be partially treated by the method applied in our country. Colorblindness is detected and the results of the contact lenses produced for this work are successful according to the type of colorblindness.
