How do I take care of my eye health?

A few days ago, an acquaintance I usually get along with was diagnosed with age-related cataracts, and they were deeply worried. As I get older, I also become increasingly concerned about eye health. Age-related eye diseases such as cataracts, glaucoma, and floaters are at the center of conversations with my friends.

I am curious about age-related eye diseases, such as whether they occur to some extent and if there are ways to prevent them.
