Thanks for sharing. I hadn't heard about this benefit. I think there are also other benefits to a focused stare. Maybe not ones that can be explained with science.

No, just glances. I usually rotate my eyes so the light is not all going into the center. It's a nonlinear response so short amounts are about as beneficial as prolonged exposure.

I hadn't heard of the red light on the retinas benefits before. Do you stare directly into the sun with focus for an extended period of time? Have you seen it turn into a spinning disc?

Have you ever practiced sun gazing?

I look at the sunrise/sunset to get the benefit of red light on my retinas.
