Scientific research has shown that the use of coloured filters on spectacles or coloured overlays laid over text can help some children and adults to read better.
The coloured overlays help to reduce the perceptual distortions of text which can sometimes be reported. This enables more fluent reading with less discomfort and fewer headaches.
Some symptoms which can often be described are:
• Eye strain or headaches when reading
• Words moving or being blurry
• Poor concentration
• Problems associated with glare from the page
A coloured overlay assessment is carried out only after a full eye examination and if symptoms are still present after the appropriate spectacles or exercises have been prescribed
This consists of allowing the individual to view text through different coloured acetates. Their response is then recorded to the different colours, and through a process of elimination, the best colour or combination is determined.
