You would still need to learn to identify (name) new hues never seen before. (After color adaptation that takes about 2 minutes.) However, the improvement in color identification ability is not yet spectacular. In the majority of cases, there is an immediate improvement in color discrimination with the Colorlite colorblind correction glasses. Colorblind people can only partially learn this ability. Color identification abilities begin in childhood and develop slowly as more shades are recognized over time. (Example: the grass is green, the sky is blue.) Nevertheless, without the help of the environment, it would be challenging. However, many colors are correctly named with colorblindness, because they have been learned. Good color discrimination is a prerequisite for color identification, as it is impossible to name colors properly unless we can distinguish them. While people with normal color vision can distinguish millions of hues, the colorblind can barely see a few hundred. Colorblind people have problems within both areas. For example, children quickly learn that a fire engine is ‘red’ and when they see other items which look the same color as a fire engine they will identify that as ‘red’ too.The two main characteristics of color vision are color discrimination and color identification. However, many color blind children can learn to identify colors correctly even if they don’t see them in the same way as people with normal color vision do. The main symptoms of color blindness in children are difficulty in distinguishing colors and making mistakes when identifying colors.
