Well, NIH posts some supporting evidence here (https://nei.nih.gov/health/errors/myopia https://nei.nih.gov/health/errors/myopia), but they seem pretty constrained to people within a critical opthalmic development window. > I leave it to you to find them on your own via google. Considering you made the assertion, is it really a stretch to do the heavy lifting yourself? For all you know, the person who asked for your specific insight ("What leads you to believe this?") tried and failed to find anything within the software engineering realm which could account for an increase in eye issues. The closest I could find among the links you provided are: > People who do an excessive amount of near-vision work may experience a false or "pseudo" myopia. Their blurred distance vision is caused by overuse of the eyes' focusing mechanism. After long periods of near work, their eyes are unable to refocus to see clearly in the distance. Clear distance vision usually returns after resting the eyes. However, constant visual stress may lead to a permanent reduction in distance vision over time. But no studies are referenced. I'm unable to find anything specifically, and I'm the second person asking you. It'd be neat to know what you read which specifically substantiated the long-term effects of near-space work on the eyes.

  Muscle strain is caused by keeping a static load on a muscle for a while without enough breaks to relax and recover. Both focusing and convergence of the eyes require muscle contraction, and can lead to eye strain. Moving work a bit further from the eyes and lower in the field of vision will reduce the amount of muscle contraction needed. Periodically focusing on more distant objects will help relax those muscles. For people working at a computer workstation, it is usually possible to arrange the computer display 3+ feet away from the eyes, and in the bottom half of the field of view. Periodically looking away from the display while thinking and remembering to get up and stretch/walk around every once in a while can make a big difference for anyone experiencing eye strain.

@eganist is exactly right. It's not considered best practice in science or on HN to make claims and then essentially say, now go strengthen my argument for me. I don't think it should be some draconian rule, but if it's not obvious to the general audience where to quickly get an authoritative source the burden generally falls to the claimant.

An alternative possibility is that spending most of your time in childhood indoors reading and using computers leads to myopia and later a career in computers. That makes more sense to me because by the time you are adult and have a job, your myopia probably isn't just developing.
