Almost All Keyboards Are Adapted For Low Vision Users
Many people haven't noticed the little raised areas at the bottom of the "F" and "J" keys, despite this feature of almost all keyboards being literally right under their noses. (The "5" key on the number pad also has a raised nub)
Those two little nubs let you position your two index fingers on the "F" and "J" keys by feel, without having to look at the keyboard. Touch-typists use them all the time to locate where their fingers should be positioned (the home row) when they start typing.
Seems that the most popular system for typing isn't "Touch Typing", but "Hunt And Peck". This unnecessarily slows down the user, but especially those with low vision, as you have to take your eyes off the screen to type, then find your place on the screen after every few letters.
There are plenty of tutorials online that can teach you how to touch type. Unfortunately, it's going to take a bit of practice and perseverance no matter how you slice it, same as any other skill.
Compare it to playing a musical instrument. If you have to look at the keys on a synthesizer or piano or the frets on a guitar, you're not ready to rock and roll; similarly (to employ an automobile analogy) if you need to constantly look at the accelerator, brake, clutch, shifter, and steering wheel while you drive, you're not going to be able to keep your eyes where you're going or look in your mirrors.
Considering how many hours people spend typing, an investment in learning to touch-type can greatly improve your productivity.
