Study Summary
The effect of tinted filters and illumination on the visual performance of patients with low vision (i.e., individuals with reduced vision that is uncorrectable with glasses, surgery or treatments) has been a topic of research and discussion for many years, yet there is no current consensus or practice standard for the evaluation and recommendation of colored filters and/or illumination intensity. Anecdotally, there have been many subjective reports of improvement in visual function and comfort with the use of tinted lenses. Previous studies have attempted to elucidate the subjective improvements observed using vision tests, such as visual acuity and contrast sensitivity, and the findings have been inconsistent. Traditionally, filters and optimal illumination are prescribed clinically through a trial and error method, which involves trying various filters and lamps haphazardly to determine which if any are preferred by the patient. The investigators are proposing to evaluate whether the illumination and filters chosen in office by participants using a new assessment tool the LuxIQ/2 translate to overall patient comfort and improved speed, accuracy and print size while reading, and to evaluate whether participants have the same illumination and colored filter preference determined by the LuxIQ/2 in a clinical office setting and in their home environment. The investigators will evaluate whether participants prefer lighting determined by the new assessment tool the LuxIQ/2 in comparison to lighting determined by the OttLite Cobra in office.
