Recommended Vision Practices

View sunlight by going outside within 30-60 minutes of waking. Do that again in the late afternoon, prior to sunset.
Get outdoor exposure for at least 2 hours a day
For every 90 minutes of close-up vision, take a 20+ minute distance viewing break
Self directed movement like walking or cycling is beneficial. This may be related to EMDR where eye movement from left to right can help with processing thoughts. The ciliary muscle can also relax as you notice objects passing in and out of your vision as you move forwards.
Tilting your eyes in your eye sockets upwards can make you more alert. You could take advantage of this by placing something to look at higher than your head level.
Myopia has an observed correlation with not sleeping in a dark room.
Make time for distance viewing every day.
You can train your vision by tracking smoothly moving objects. aka "smooth pursuit"
You can train near-far visual training, 2-3 minutes, 3-4 times a week
Exposure to red light early in the day has shown promise in improving vision in adults 40+ years in age.
Is also a proponent of printing out a Snellen chart and experimenting with it.

(From the sleep recommendations newsletter:)[1]

View sunlight by going outside within 30-60 minutes of waking. Do that again in the late afternoon, prior to sunset. Ideally without sunglasses, but don't look at light so bright that you need to squint.
Avoid viewing bright lights—especially bright overhead lights between 10 pm and 4 am.
