Abstract

An experiment was conducted to indentify and analyse any positive effects of lrlen lenses upon visual perceptual performance of children previously diagnosed as Scotopic Sensitive. Pupils performed a letter identification visual search task under lrlen lens, Untinted lens, Plain Grey lens and No lens conditions. No condition was associated with superior performance on the task. Nevertheless, several children reported that untinted or plain grey lenses helped them perform the task. The study provides no evidence to suggest that lrlen lenses improve visual performance.
