Effects of anthocyanin, astaxanthin, and lutein on eye functions: a randomized, double-blind, placebo-controlled study.

We examined the effects of a test food containing anthocyanin, astaxanthin, and lutein on the eye function in healthy Japanese adults with eye fatigue after operating visual display terminals. Forty-four subjects were randomly but equally assigned to the active or placebo group. Two active or placebo capsules were taken once daily for 6 weeks.

Effects of MaquiBright on improving eye dryness and fatigue in humans: A randomized, double-blind, placebo-controlled trial.

This study aims to investigate the effects of MaquiBright, also known as BrightSight, a standardized maqui berry extract, on improving eye dryness and fatigue in Japanese subjects (aged 30-60 years) experiencing eye dryness, eye fatigue, and ≥4 h of visual display terminal (VDT) work daily. Seventy-four participants were equally but randomly assigned to either a MaquiBright (MB) or a placebo (P) group, wherein each participant consumed one capsule daily for 4 weeks of the appropriate treatment (MaquiBright 60 or 0 mg). Eye dryness and fatigue were measured using the Schirmer's test, tear break-up time (BUT) test, pupillary response, and flicker test before intake and 4 weeks after intake.
