Short answer
Slightly, on the evidence so far. Andrew Huberman, on his own show, cites a few solid studies where lutein, zeaxanthin or astaxanthin slowed advanced age-related macular degeneration, but the effect was slight. In male mice, ITP data showed a 10% lifespan increase.

Astaxanthin may help the eyes slightly. Andrew Huberman, on his own show, points to a few solid studies in which lutein, zeaxanthin or astaxanthin slowed advanced age-related macular degeneration. He calls the size of that effect slight.
Astaxanthin is relevant to the eye because it crosses both the blood-brain barrier and the blood-retinal barrier. It is recommended for eye health and blood flow to the eye.
The Interventions Testing Program (ITP), a mouse lifespan study, found a 10% lifespan increase in male mice, though more dose-response research is needed. Astaxanthin is also a potent antioxidant found in krill oil and salmon roe, and it activates FOXO3, a gene tied to longevity. It shows up in at least one daily supplement stack.
