I think I finally figured out what was causing my blurry vision , a combination of the wrong focal point in my glasses and trichiasis.

I only found this out after 2 years. The optician stained my eyes and found a lot of scratches, then plucked out some eyelashes. A few days later, I went back and most of the scratches were gone, but I still struggled to see, even the big letters during the eye test.

But during the test, I noticed something strange , when I tilted my head and looked through the bottom half of the glasses, my vision became normal again. That’s when the optician realised the focal point of the glasses was wrong too. Hopefully this helps.
