Don't worry about "eye strain." Muscular use of eyes has no long term effects. Eye dryness does probably does but I don't know much about mitigating it.
Blue light affects your circadian rhythm, use blue blocker glasses, use F.lux. Adjust phone and device brightness to be the minimal amount you're comfortable reading. Don't use full screen brightness at night, especially because your pupils are more dilated in lower light environments. Use dark mode everywhere you can.
Blue LED light may be toxic to your retina with long term exposure. The jury is still out on this one, but the above steps will help mitigate the issue.
The other issue is emmetropization and nearsightedness. Incredibly important to understand for children. It will affect you too if your eye prescription continues to change. It usually stops in your 20s (your vision stops getting worse), but for some it continues to degrade past that. Holding things close to your face keeps your peripheral vision in focus, making your eye think it's over-focusing, so the eye grows longer (more near sighted) to try to correct. This happens without the brain's involvement, it's all based on focus on the retina. Your eye doctor should know about this process, should know about low dose atropine, and should know about glasses with fogged edges, especially for children. Most don't.
- TedDoesntTalk 4y agoAsked the same question to an eye doctor. He said to look away for the screen periodically, at a different distance so your eyes must change focus. It is this focus change that keeps them exercised. He said his patients with the healthiest, aged eyes are those who knit. They are constantly looking closely then away, closely then away, ad naseum.
- stevebmark 4y agoI too have seen eye doctors that extrapolate incorrect conclusions from anecdotes. I'd consider looking for a different eye doctor. Reducing focus in peripheral vision may help slow the progression of myopia (nothing can reverse it), so the advice might be ironically helpful even though it's based on complete misunderstanding of how the eye works. Again, it has nothing to do with muscle use nor the action of your lens changing focus.
- normiename 4y agoCould you please explain, what your original comment means. Holding objects close to our face would cause an increase in our eye power? But again you also mention should reduce focus on peripheral vision which would be achieved by holding close to eye. What is the suggestion here pls? Sorry I am ignorant and really want to know.
- CraftThatBlock 4y agoSomething I've heard in this vein was the 20/20/20 rule. Look 20 feet away for 20 seconds every 20 minutes.
- lost_tourist 4y agohasn't the "blue LED light messes with your sleep" been proven to be a myth?
- stevebmark 4y agoThere's something about threads about eye health that lead to a lot more people completely guessing at science and biology, like yourself. I don't know why it's such a poorly understood subject, and why so many people guess at it.
- Asraelite 4y ago> Blue LED light may be toxic to your retina with long term exposure. I wasn't aware of this. Do you mean LED light specifically? Is it in some way inherently different from the much more intense blue light of the sun? I don't see how light from one source can be any more damaging than from another source; it's all just the same EM radiation.
