"Chromatic Glass" is a color vision assistance tool for persons who have difficulty recognizing specific colors or perceiving differences between specific color pairs due to a color vision deficiency.
Congenital color vision deficiency can be classified into three major types: Protanope / Protanomal, Deuteranope / Deuteranomal and Tritanope / Tritanomal. People with different types of color vision deficiency perceive colors differently.
The colors which can be recognized or distinguished by color deficient persons are different from color normal persons. In addition, such conditions may occur owing to an acquired illness.
"Chromatic Glass" helps users to recognize and distinguish such colors by making a special modified color image based on scientific theoretical methods in real-time and displaying it and the original image alternately.

Features

  • Supports the three major color vision types -- Protan, Deutan, and Tritan.
  • While there are a range of colors that color vision deficient type people have trouble seeing, generally, Protans and Deutans have difficulty in perceiving differences between red and green. Protans also have difficulty recognizing deep red. Tritans have difficulty distinguishing between green and blue. This application is designed to make colors easier to distinguish for persons who have such color vision types.
  • This application was developed by Kazuonri Asada (Ph.D. Medical Science and Ph.D. Media Design) and is released free.
