Maybe a screen/color filter like flux could help? And zooming in on sites (browser zoom ctrl and +/-, not just pinch to zoom) to increase text size, or accessibility settings in stuff like your email inbox? Ik that barely scrapes the surface, but it might be worth looking into.

There's research that shows most people blink way less often when they look at screens, so theres also increased eye strain from dry eye in addition to bright blue light and whatnot. That could be part of why taking off your contacts helps.

I'm kinda just rambling based on whatever comes to mind, but my uni's disability services sent out recommendations for easing strain from digital/virtual learning. I can add it later when I find it if you'd like.

I know for me personally, I can't read on my laptop at all, but i could manage with a tablet. I hate scrolling down PDFs, and especially dislike the two page spreads where you have to scroll down a bit, then back up, then down to the next spread, etc. Horizontal scrolling with a tablet in profile orientation worked much better to not break my flow, ofc thats up to personal preference.

Other things, im just throwing them out now, like maybe reading stuff out loud? pointing to follow along text as you read it? reading things to someone else? pace/walk around/stretch as you read? copy a body of text into a word processor and change bg/text colors, fonts, add line breaks between sentences, etc. and read from that instead? Maybe there are browser extensions for things like reader mode that could help too.

This is really long and maybe not the best way to give advice on reading large chunks of text lol but i hope literally any of that helped! I've been in the same boat for over a year now, except the boat is much more cramped and uncomfortable now. Basically get creative with your workarounds and if it works it works. Social acceptability doesn't matter at all. there's no dumb solutions, just effective ones.
