Vischeck

Product Description: 

Vischeck is a way of showing you what things look like to someone who is color blind. You can try Vischeck online by either running Vischeck on your own image files or running Vischeck on a web page. You can also download programs to let you run it on your own computer.

Vischeck is a computer simulation of the entire process of human vision. The model can be divided into three parts.

The first stage includes the physical properties of the display devices (including various CRT and LCD monitors, and standard CYMK print on paper), the ambient lighting and the effects of physiological factors such as corneal haze, lens opacities and short or long-sightedness which might degrade the optical image.

The second stage of the model describes the transformation of optical image on the retina into a neural representation of that image in the optic nerve. At this point, visual disabilities and anomalies such as color-blindness or retinal degeneration can be included in the model.

The final stage in Vischeck is a model of human cortical vision. At this stage, we include information about the way in which color, spatial patterns and motion are combined and processed in the visual cortex, to form the observer's perception of the image
