Does sunlight help eye health?
Sources:
Yes, sunlight does help with eye health, particularly in preventing myopia (nearsightedness). According to Andrew Huberman, spending at least two hours a day outdoors can significantly reduce the probability of developing myopia. This effect is attributed to sunlight promoting the health of the eye's focusing mechanism, responsible for adjusting vision 1.

Andrew explains how spending two hours a day outside can offset the formation of myopia. Sunlight promotes the health of the eye's focusing mechanism, which is responsible for nearsightedness. Staying indoors and looking at things up close can lead to visual defects.
