To my knowledge, eye muscles may get sort-of ‘cramps’ where they get ‘stuck’ in the same flex configuration as they were, if you focus on the same nearby distance for hours and hours. Purportedly, it's even classified as a distinct kind of myopia (the only one that's fixable with exercise), but dunno how legit that is. What I know for certain, though, is that regular exercises that move the eyes and the focus relieve the strain a lot. Rotate the eyes, move side to side, move the focus back and forth, that sort of thing. Also focus on stuff outside the window more often. As for contact lenses, afaik they're trash with computers because they make the eye dryer in addition to what you already get due to blinking more rarely. At least that's how it was back in the day, when I didn't last more than a month or so with contacts at computers.
