The effects of carrot carotenoids on visual function in long-hour computer users: a pilot study
Year: 2014
Type: dissertation
Study designs: Randomized Controlled Trial, Clinical Trial
Abstract: Carotenoids are essential for visual function, however their potential role in Computer Vision Syndrome (CVS) is not known. By providing carrot powder, this study examined carotenoid metabolism and visual function in CVS. CVS participants were recruited into a double-blind, placebo-controlled, repeated measures trial (n=19, ages 20-65) and were randomized to 2 supplementation groups; control (15g cream of wheat powder) or carrot enriched (15g carrot powder, 33% of vitamin A RDA for adults) in an isocaloric pudding and yogurt for 4 weeks. Retinal function, self-perceived vision status, and plasma carotenoids/retinoids were assessed, along with plasma lipids and oxidative stress markers. Photopic b-waves marginally improved following supplementation reflecting higher phototransduction, possibly due to increased plasma carotenoid/retinoid levels. LDL cholesterol and oxidative stress markers showed trending reductions illustrating a protective role of the carrot. Carrot powder, at a minimal supplementation dose, can be recommended for CVS.
