Reading small font text has not been shown to cause damage to the eyes (although you may experience eye strain from prolonged accommodation). However, long-duration near work has been found repeatedly to be associated with a greater risk of developing myopia or nearsightedness: https://bmcpublichealth.biomedcentral.com/articles/10.1186/s12889-022-14377-1

I’m a visual psychophysicist. We often recommend that people take breaks when doing near-work. The 20-20-20 rule: look at something that is 20 feet away for 20 seconds every 20 minutes.

Interesting! Do you set an alarm for every 20 mins?

[–] cheese_greater@lemmy.world 1 points 10 hours ago

So you do psychophysics?? Would you mind if i occasionally drew on you for limited questions or prompts for these type of similar inquiries?

[–] CocaineShrimp@lemm.ee 5 points 11 hours ago (1 children)

Might be just a rumor / old wives tale, but I thought the small text on screens / pages up close, without breaks, resulted in poor vision?

[–] cheese_greater@lemmy.world 3 points 10 hours ago

It might be complicated by me possibly being nearsighted
