Why can’t we custom correct vision?

854 views

So, when it came to the genetic lottery category eyesight, I did not win. This is my prescription:
Left eye: -1,00
Right eye: -4,00

I also have astigmatism only in my right eye. Getting contact lenses and glasses has always been a pain, but I digress.

I have an office job that involves staring at a computer for most of the day. When getting my glasses, I asked if it made sense to wear them when working, but the optometrist said not to do that since I’m near-sighted anyways. The issue with that is that my right eye is so bad, that even if I’m sitting half a metre away from the screen, I cannot see clearly out of my right eye. So I’m basically only using my left eye to see when I’m working. I then asked if it was possible to get -3,00 contact lenses to wear in only my right eye, so that my eyes were at least the same and so that the workload on my eyes would be evenly divided. He chuckled and seemed confused, and then when he saw that I was being serious, he said that that’s not possible. He didn’t explain why.

I’m obviously not an expert (hence why I managed to make the optometrist laugh with my silly question), so please explain like I’m 5: why is this not possible? Why can’t I wear a -3,00 contact lens in my right eye to have it be the same as my left eye? Why can’t we custom correct vision?

Your doctor was on autopilot and wasn’t really listening to you. Just go to a different optometrist.

Go see an ophthalmologist. Optometrists are doctors, but they are not physicians or medical doctors.

An ophthalmologist, a medical doctor, is able to do far more than an optometrist. It has been brought up here many, many times that there are major differences in their education and capabilities. An ophthalmologist, if an available option, is vastly superior in every way and anyone stating otherwise is likely an optometrist.

Optometrist here. You absolutely can do this if you want and if you’re happy being -1.00 in both eyes for distance (driving might be an issue). If you’re over 40 this would actually be pretty great for you.

You mention astigmatism but haven’t written how much in your prescription. That could also be a caveat if there’s a high amount.

The fact that you have to come to reddit asking about medical advice shows that you need another doctor. He should be your best source of information, it’s his job.

As far as I know you can in some cases. Used to work with a woman that went to eye doctor that would grind(or whatever the term is )his own custom contact lenses to exactly match perscription so she would wind up with slightly better than 2020. Problem is they were retiring and no one else did this anymore, so her vision was going to take a hit. This was in 2002 or so.

Have you ever consulted with a doctor who does some sort of laser corrective surgery?

I went from 20/250 to 20/15. Worth a shot.🤷🏻‍♂️

You need a better optometrist. Mine gave me two prescriptions: “normal” R -3.5 L -4.25 and a “computer work” script R -2.75 L -3.5 – both with progressive bifocal. The normal lenses give me excellent distance vision, and the computer lenses focus perfectly at the 20″ distance to my computer screen. Yes, I used [Zenni.com](https://Zenni.com) since the eye doctor’s office wanted nearly $600 each for the glasses, and Zenni charged $50 each.

Asymmetric contacts are quite common. My wife has a script for distance vision in her right eye, and reading distance in her left. That would drive me a bit crazy but she’s fine with it.

I don’t know how old you are, but if you are near sighted and below 35, you’d have to wear your full prescription power all the time. If you dont wear specs or contacts, your vision would continue to deteriorate because your eye muscles are over-exerting to correct for the poor vision.
My vision drifted from -1.5 to -4.0 because I neglected wearing my glasses.
Oh, and you need to find a new optometrist.

With -4 it absolutely makes sense to wear you glasses while working. I have -4,25. It’s possible that having another pair of glasses specially made for desk work will be more comfortable for you. For me it’s not necessary but might be when I get older.

I have amblyopia and esotropia, meaning my prescription for each eye is DRASTICALLY different, making me have lower than -3 in my right eye compared to -0.5 jb my left. I have never had any issues getting glasses or contacts. Your optometrist is shit, go to a different one.
