Very good piece of information.
I have been taught from the childhood that -just looking at green trees/leaves/bushes(from near) just after waking up in the morning before looking anything else improves your eyes' health and sight.
And I follow this as usual as possible since I can't always find green sights around me. 😃😃

Although I can't find such benefit on eyes in your post, hopefully, this might still beneficial for my overall health as you mentioned above.
Cheers !!
