Love this topic!
In my late 40s, I noticed that I and most others my age were doing the old “hold things an arm’s length away to read them”. Most people capitulated eventually and bought reading glasses. Instead I read a lot about improving/avoiding age-related eyesight declines. The exercises recommended sound like exactly your lifestyle!
They are things like:
Practice switching near and far focus (for example hold a finger near your face, bring it into focus, then look at something far away)
Get plenty of sunlight
Exercise your peripheral vision by looking in a zigzag fashion, top left, top right, bottom left, bottom right, then do circles each way
Take computer screen breaks, make sure you blink sufficiently and avoid eye strain
Do “palming” (press palms to eyes) and “sunning” (close eyes in sunlight)
Do not wear glasses
I have resisted getting reading glasses and now am approaching mid-50s! I can read books easily in bright or even low light.
I can thread a needle, to my amazement, but I do see double!
Computer/screen time severely hurts my ability to change focus and destroys my near focus. I do it anyway, ha! And am not good about taking breaks anymore. However being FIREd, at least I don’t have a computer-oriented job. Still too much screen time. My primary computer addiction is reading (surprise, I’m on this forum) and I believe that is the most detrimental to your vision. Watching a video can be done more from a distance (often I’m doing chores while videos are running, more like the radio). That’s also why I prefer printed books to reading on a device.
The issue with screen time is the fixed-distance focus, lack of blinking, and possibly the blue light (jury is out on that). I also make sure I have nightshift turned on my devices, which makes everything orange-ish after sunset. I used to do this before Apple made it a thing. I had an app for it, as well as an app for taking eye breaks.
I can go on and on about this! Will add more later. Anyway the point is the science is now supporting the idea that middle-age loss of close vision due to hardening of the lens CAN be improved by working the focusing muscles!
When those new eye drops came out that help you see better I KNEW I WAS RIGHT!

Oh, and as a parent, don’t get me started!!!!
Kids today need to protect their eyes, their posture, and their hearing because of overuse of devices!!!
