Excessive blue light can cause sleep and mood disorders, leading to depression.

Why do blue light glasses hurt my eyes?

There are other ways that an excess of blue light can be harmful, too — the eye isn't built for blocking blue light, virtually all of which penetrates the lens and cornea of the eye and directly reaches the retina, and too much exposure can cause damage to the retina's light-sensitive cells, which may cause effects ...

Is blue light eye damage reversible?

Those affected by age-related macular degeneration experience blurred sight or loss of sight in the center of vision. This makes detailed vision, such as reading or seeing faces, difficult because the only remaining vision is the less-detailed peripheral vision. Once the damage occurs, there is no way to reverse it.
