I had my eyes retested a few weeks ago. The results were that both of my eyes are the same, but one eye feels blurrier than the other. And if I put a hand over one eye at a time, one is blurrier than the other. I didn’t say anything at the time because I was too shy and thought I’d trust the process and they know more than me. Now I have new glasses and whilst everything is a lot clearer, one eye is still straining slightly to see, and I am possibly stuck with these for the next 2 years. Maybe the difference was so minimal that a different prescription wouldn’t work? I don’t know if it was a mistake in the testing process or if my prescription is right/I’m just adjusting
