Colorimetry testing is a technique used to improve the comfort and ease of reading for those who suffer from visual stress.
Scientists use the term ‘Visual Stress’ to describe a certain set of reading difficulties suffered by adults and children. The condition is related to light sensitivity and is often experienced by those who suffer migraine and epilepsy disorders.
