My old contact lens prescription was -6.5 and -4.25. Several years later I was prescribed a different kind at -4.75 at each eye. I’m wondering if the doctor messed up the prescription by entering the same value twice, or can anyone think of a reason for actually reducing the correction on my weak eye. I recall being told one eye was a lot more presbyophic than another, this problem has gotten significantly worse since my last visit but as of now I don’t want to deal with bifocals so I asked for single vision lenses for both glasses and contacts.
Although my eyes are not as different-from-each-other as yours, I am dealing with the same thing.
I originally went to my optometrist and said, “I want to get back into billiards and target-shooting bows and pistols.”
The optometrist did his diagnostics, figured my eyes were basically -8.25 and -7.0 and fitted me for lenses. They were great, I went pistol-shooting twice that year and was refreshingly accurate. But I didn’t play billiards or do any archery so, when I went for the next annual vision check-up I admitted, “Well, I didn’t do all that much that required both close and distant accuracy, so let’s not worry so much about that this time.”
So the optometrist did his diagnostics, figured my eyes basically hadn’t changed, and fitted me for -7.5s in both eyes. The optometrist explained it (a couple different times) but I don’t remember the details. Basically it seems to be a matter of ‘tricking’ the brain into averaging the over- and under-corrections for my eyes and treating them as good. For normal daily use my vision is actually more accurate – better than with the two separate better-customized prescriptions.
When I go to the range (which is, unfortunately, rare these days), I replace one of my lenses with a -8.25 and I can still consistently group within a Quarter at 10 yards. That’s good enough for me.
–G!
