Important question about blurred vision?

I've been researching, and I have a question: if you get the kind of unfixable blurred vision from optic nerve damage or burst blood vessels within eyes, can it makes you more near sighted or will it make your vision blurier in general, close or far? I was diagnosed a month or two ago with 20/40 vision in my left eye and 20/80 in my right. If I put my hands right in front of my fave or look at the keyboard I type on, its clear. If I look at something farther away, its very blurry in my right eye.

A month ago I started on adderall and developed a minor eye infection of some sort that gave me eye boogers all day and made me constantly blink. I still blink a lot and HARD as a compulsion. I'm not sure if my vision is damaged from popped blood vessels from blinking hard or if its in my head. Can that make you more near-sighted?

Also, my blood pressure is still low despite the medicine but I don't know about my eye-pressure.

And yes, I'm making an appointment to see an ophthalmologist instead of just a glasses doctor. Thank you so much if you can answer.

Your questions are all very good and well thought out. I am not thinking that you are having an optic nerve issue, but I am wondering if you are having some other issues that need to be adressed by the Ophthalmologist. You mught just need some glasses, or it might be something else. Usually the things you are worried aobut do not just being on straight myopia, but not being a doctor I can not tell you what it would be. Just make sure you take all your doses of your meds with you and any glasses you do wear and let them know what kind of treament you had for your eye infection. They need to know all that stuff.
