... reading books, screens ect that are about half a meter or the distance you would usally hold a book.
My vision keeps going blurry and its very hard to refocus i need to squint and stop. After about 5-10 minutes reading squinting or trying to refocus does nothing.

It is making it so difficult for me to read. I can read the board at school, and watch tv perfectly fine.

I got my eyes tested and the optometrist said he could see i was a little bit off with the test, especially the one that required close up testing. However it was nothing to worry about and he said have a break for 1 minute every half hour.
I have been doing that and there is absolutley no change.

My parents are refusing to take me back and are 100% against getting glasses for me. I shouldn't have to. But could someone please tell me how to convince them I need glases because it is so hard everyone else can see fine except me

P.S i'm a 16 year old guy
