VisionPure™ is a softgel dietary supplement containing fish oil, lutein, zeaxanthin, and vitamin D. The intent of the VisionPure product is to assist in maintaining eye and cognitive health while helping to provide protection against blue throughout the day. In this pilot trial, approximately 16 participants will be recruited and randomly assigned to experimental and placebo conditions. Participants will consume 1 serving (2 softgels) per day of their respective study condition for 60 days. Prior to and following the 60 day supplementation period, participants will undergo a series of optometry and cognitive examinations to quantify eye health and cognitive function outcomes.
