Vision and Memory Flashcards
Vision begins in the eye which receives the inputs, in the form of light, and finishes in the brain which interprets those inputs and gives us the information we need from the data we receive.
Visual stress is sometimes known as “pattern-induced epilepsy” and while this is the most extreme manifestation of visual stress; it’s worth noting that visual stress can be induced at milder levels by striped patterns in most people.
Even normal text (which is arranged in horizontal stripes) can cause problems for some people and it may be that certain fonts exacerbate the problem. Visual stress in this instance can distort print and cause rapid fatigue when reading. In some respects, the effect of visual stress is very similar to the ways dyslexics see print, as pictured below.
Color blindness is mislabeled. What is color blindness?
It’s not blindness but rather a deficiency in color vision. It is the inability (or sometimes decreased ability) to see certain colors, or perceive color contrasts in normal light.
Designers should be aware of visual stress and color blindness and ideally test their designs with people known to suffer from these conditions to ensure that the effects are muted or eliminated entirely.
Designers need to be aware that there are common processing errors and in particular to be aware of visual stress and color blindness so that they can adjust their designs to minimize the impacts of these errors.
Which color pair does color blindness most typically affect?
Red and Green.
