ABSTRACT:
A quantitative visual test measures the rate at which an individual is able to complete a defined visual task, either on paper or on a self illuminated screen. The task involves comparing a plurality of similar appearing numbers to determine if they are an exact match within predetermined levels of time. Inability to complete the test within the predetermined level of time indicates the likelihood that the individual will exhibit visual stress and dyslexia. Individuals under such stress are then remediated by the use of adjusted lighting environments sometimes including other visual aids.
