Coloured Filters and Autism Ranking: Insufficient/Mixed evidence

Future Research

Summary of Existing Research

There is no research evidence to suggest that coloured lenses are useful for people on the autism spectrum with visual processing difficulties or visual stress.

There is some very limited, low quality research evidence to suggest that coloured overlays could be useful for some children and young people on the autism spectrum with a range of problems including difficulties with reading and recognition of emotions in other people. 

This lack of evidence does not prove or disprove the effectiveness of coloured lenses for people with autistic spectrum disorders. It simply shows how little research has been conducted to date.

Recommendations for Future Research

Small-scale, pilot trials of the effects of coloured filters could be carried out on individuals on the autism spectrum to determine their effectiveness and safety.
