Hi, I m a 19 year old female who has worn glasses for the past 5 years. About a year and a half ago I got a new prescription. However he had said there wasn t a huge change in my prescription. Present day, my eyes are really bad! Everything at long distances is super blurry. At first I thought it was because of high amounts of caffeine, or I was really tired. I would choke it up as bad eyes, but The weird thing is, is that once in a while it s like my eyes focus and I can see the far away stuff, but it only lasts for a couple seconds. And caffeine or sleep doesn t seem to effect anything. Any ideas on why my eyes would suddenly focus? Or why they ve gotten so weird in the past year and half? I do have an eye appointment next week.
