A 2023 meta-analysis found that saffron supplementation can enhance contrast sensitivity and slow vision loss progression, making it a valuable addition to modern eye formulas.58 Astaxanthin complements the formula by crossing the bloodretinal barrier and helping protect photoreceptor cells from oxidative stress.2 When combined with lutein and zeaxanthin, it has improved visual sharpness, eye fatigue, and contrast recovery after glare exposure in human studies.14 While MacuGuard provides 6mg of astaxanthin rather than the 12mg found in our top recommendations, its combination of carotenoids and saffron remains a compelling option for readers focused primarily on eye health
