Low Vision Patients' Preference for Colored Filters and Illumination for Near Reading Determined by the LuxIQ/2

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.
