Why do glasses only improve our sight to around 20/20, instead of going to 20/10?
In: 7
My glasses are able to correct my vision to 20/15 so it is possible to get better than 20/20 through glasses alone. I asked my optometrist your question a while back and she said that my brain isn’t able to process a higher correction. I don’t know the specifics of what that meant or if she was trying to simplify a more complex answer.
My prescription can also be slightly better for seeing objects far away but I told my optometrist that it reduces my ability to see objects close up (like when I’m reading a book my eyes aren’t able to focus if I have it too close to my face), so i feel that part of the answer is balancing near-sightedness and far-sightedness.
