Methodology
Randomised double-blind placebo-controlled trial of 24 mg/day macular carotenoids (lutein, zeaxanthin, meso-zeaxanthin) for 6 months in young adults with high screen exposure.
Key Findings
Macular pigment optical density, contrast sensitivity and photostress recovery improved, and headache frequency, eye strain and sleep quality scores were better than placebo.
Conclusions
Macular carotenoid supplementation improved visual performance and screen-related symptoms in healthy young adults.
Limitations
Small single-centre sample; self-reported symptom outcomes; industry supplied supplement.
Supplements Studied
Macular pigment optical density, contrast sensitivity and photostress recovery improved, and headache frequency and eye strain decreased versus placebo.
Outcomes Measured
Contrast sensitivity and photostress recovery improved with macular carotenoid supplementation in high screen-time adults.
