Anomaloscope Color Blindness Test
An anomaloscope is based on a color match. Two different light sources have to be matched to the same color.
The first anomaloscope blindness test was developed in the 20th century, and since then, it is the most accurate blindness test used by eye specialists worldwide.
An anomaloscope test is based on a colour match. The user needs to match the same color of two different light sources. On the left side, you have a yellow color that can be adjusted in brightness. The right side consists of red and green light; the user needs to match the left and right site with an equal proportion of color.
As every color on a computer display is made up of the three base colors, red, green, and blue, an anomaloscope can’t be reproduced online.
