Can strep throat cause white spots and feeling of something stuck in the throat?

Hi doctor,

I was diagnosed with short-sightedness more than five years back. A year before, I noticed my left eye started to cross outward, occasionally. When looking to the right side (medially), it crosses up a little. When looking upward, it partially shifts to the left. And today, it started to cross few degrees to the left side while looking directly forward. Four years ago, I hit my eye with a doorknob that resulted in pain for a few days, and there was a discoloration in the eye. Could that be a possible reason? The left eye usually dries faster and burns when I use it while closing the right one. I have no idea if that is a reason too? I cannot reduce my working hours on screen, and I do not know what to do because it is becoming more noticeable.
