• ↔Astaxanthin

  Complementary carotenoid distribution: lutein + zeaxanthin concentrate at the macula center; astaxanthin populates retinal periphery + scavenges ROS. Long screen / eye strain / age-related AMD prevention — three-component stack is the rational combination.

• →Eyes · Myopia · Screens

  Lutein and zeaxanthin stack in the macula as filter and antioxidant, protecting the retina against ageing; they cannot shorten an eye that already elongated — macular protection and myopia control are different problems.

• ≠Insomnia

  Screens do two separate things — to eyes and to sleep — and blue-light marketing fuses them: eye strain is dry eye from blink rate dropping to a third plus sustained focusing effort, while evening screens act on melatonin timing. The first needs 20-20-20, the second needs light scheduling.
