I'm hopeful that the shift to VR from PC gaming and perhaps also office productivity will help with myopia. Might seem counter-intuitive given the VR lens is next to the eye but focus in VR is in the distance. Even productivity in VR is usually done on huge screens further away from the user than traditions pc screens.

Wearing contact lenses with VR is a huge difference compared to without. So I think there is some potential in what you are saying. There could even be room for eye training apps etc.

I wore glasses for a few years in high school because I had trouble seeing the blackboard from anywhere but the front row. I started hiking and kayaking every day, especially in places where I could see for many miles. I also migrated from CRT to LCD to LED screens, and more recently to e-ink devices when possible. Very fine print in a dark space is hard to read, but I can read a moving US license plate from six bloc…

I too use eInk whenever possible but that's just for reading (a passion of mine). All current computer monitors are LED AFAIK, is there any research tho that it's better for sight, or are you simply stating that you migrated as the technology changed?

I'm thinking that OLEDs are the best looking but one of their weaknesses often mentioned is that they aren't as bright; if you have lots of light (ideally natural sunlight) they may prove to be counterproductive if you have to strain to see due to appearing dim.

You're getting far-sighted as you're getting older.

I call it "wisdom". :-)

More seriously, though, I am not far-sighted. I do not need corrective lenses to read books, newsprint, magazines, or labels at the grocery store despite the possible genetic predisposition baed on the need for reading glasses by my parents and siblings. I often have to read very fine details on nautical charts, sometimes in a seaway, sometimes at night with the use of a headlamp.

Exhaustion definitely changes my eyesight. I'm coming off of two days of kayaking and camping with high school kids followed by an intensive four hour lesson teaching rescues. (Imagine ~3600 boat-poses per hour, then subtract a few hundred and replace them with pulling swamped boats out of the water and across my lap to empty them, climbing out of the water and into the boat to demonstrate a dozen types of self-rescue.) I tried to read last night but my eyes could not focus; I vaguely remember making my way toward bed but woke up twelve hours later downstairs on the floor.
