I also recommend an onscreen magnifier that appears and disappears on hotkeys. I use MacOS' built-in one, set up to show when ctrl-alt are held. I have only moderate myopia, but the magnifier makes it much more comfortable to look at small-ish things on the screen. There's an image that you wish was bigger? No need to open it separately or bend forward—just mash the keys, bam, it's half the screen now.
On the non-hidpi screen the magnifier pretty much took me to the days of 800x600 screens, causing frequent reflections on how the times change. But on hidpi, it's more like I get a 1280x800 screen in the magnifier. Works like magic for images with small details, e.g. aerial photos: almost like peeking through a telescope.
