Clarity Colorimetry helps schools assess visual stress in pupils who may experience discomfort or difficulty when reading. Using colourimetry, we can identify whether a particular coloured overlay may make reading more comfortable for an individual pupil. This can be helpful for pupils who experience symptoms such as visual discomfort, headaches, eyestrain, or words appearing to move, blur or distort when reading. Our service gives schools a practical way to identify pupils who may benefit from further support, helping them read with greater comfort, confidence and ease.
