Pioneering technology informed by experience

Visual stress is a term used to describe visual discomfort and perceptual distortions. In some cases, the symptoms of visual stress can be reduced by the use of coloured filters: a coloured overlay placed over text or coloured lenses worn in spectacles. It is thought that offering a large number of colours allows for optimal results.

To identify visual stress and prescribe precision colour appropriately, an eyecare professional will work with you to follow a 3 tier protocol.
