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.
So is that why my teacher's computer kept having a prompt show up saying "stare far off" or "look out the window"?
Interesting! Do you set an alarm for every 20 mins?
So you do psychophysics?? Would you mind if i occasionally drew on you for limited questions or prompts for these type of similar inquiries?
