Why can’t we custom correct vision?

1.05K 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?

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.
