It's a bit hard without knowing what games you like.

Maybe Transistor? The combat is fast, but it's mostly done through active pause.

Star Vikings is a decent, funny puzzler, 2D and very clear visuals.

Wonder Boy is a great 2D platformer, very nice, clear graphics and not too crazy fast gameplay.

Guild of Dungeoneering is very pleasant twist on dungeon crawling, with clear 2D graphics.

Reus has very nice 2D graphics, not too much detail to worry about and a rather slow, relaxing pace.

I don't think having the use of only one eye would affect your gaming skills at all, nor change the types or genres of games that you have to play, generally speaking.

a screen is flat, it only creates the illusion of depth, so as long as you are using a screen and not something like VR Googles (which has two screens, one for each eye) then there is no difference if you have one or two, or even three, eyes.

(though with the third eye you do get the the ability see things before they happen, a clear advantage in twtich based and MP games)

Everybody has already said most of the things I could say, save for:

One eyed gaming sounds like the absolute in toxic gaming youtube channels.

You could look into (please don't hate me) games with a high degree of pregnancy (as in gestalt's 'Prägnanz'), with easily identifiable objects and figures, maybe that way you won't stress your vision too much. Something slow and chill like Virginia, Spiritfarer, Rime, Gris, etc.

The other option would be to peer into the warp and try to unravel its mysteries. Just kidding. Wishing you a prompt recovery buddy.

Closing one eye and looking at my monitor, it honestly doesn't seem crazy different. Maybe it's because I have a big monitor.

Sort of related, all my hobbies are so visual (games, movies, traveling) I am always pretty worried I will get severely visually impaired and basically lose everything I care about. It's a freak thought.
