Yes, elbinario is on my mind but your efforts need mention too!

I hope your eyesight won't deteriorate any further. I can relate to it as mine suffered significantly in the past years due to a cataract in both eyes. It's still managable, and the ophthalmologist suggests not to do a surgery right now. But it makes daily life cumbersome, like I look around in a room filled with cigarette smoke. Sometimes during work I rather have to feel than see the dirt I'm rinsing off the dishes ;-)

Perhaps our parents have been right back then: Don't sit too close to the TV (or monitor) screen, it'll hurt your eyes, the admonition went. And obviously we didn't listen.

All the best to you!
