Can vision problems reverse themselves with age?
I’ve been nearsighted for most of my life. I began wearing glasses in the fifth grade and switched to contact lenses nearly full time when I was in college.
Over the years, my vision has gotten progressively worse. Each eye exam resulted in a slightly stronger prescription. I was lucky, though. Even though my natural far vision is bad, it’s very correctable. The contact lenses I’ve been wearing for at least 20 years — Acuvue disposable daily lenses — fit me like they were made for my eyes’ size and shape and bring my vision to 20/20 or better.
My near vision, on the other hand, is amazingly good. With glasses and contacts off, I can see nearly microscopic detail of things within 4-5 inches of my face. I can even read the micro text on $100 bills.
Of course, with contacts on, that close vision disappears. And as my far vision prescription got stronger and stronger, my close vision with contacts on got worse and worse.
At first, I combatted the close vision problem by letting my stronger eye do distance and my weaker eye do close vision. The ophthalmologist did this by prescribing a strong lens for my right eye and a much weaker lens for my left one. This worked pretty well, at least for a while. But then I realized that what it was really doing was making both my far vision and near vision less than satisfactory. So I went with contacts for good far vision in both eyes and began using reading glasses for close vision when my contacts were in. My back up eyeglasses were progressive lens bifocals.
Last year, my contact lens prescription was -6.50/-7.00 (right/left). My understanding is that that’s the equivalent to 20/650 and 20/700. Again, with the lenses in, my vision was about 20/20.
This year, however, I began having trouble with my vision. It started in the autumn when allergy (?) issues made it impossible to wear my contacts for more than a day or two. My eyes were itchy and teary. I wore my glasses quite often. I could see okay through them, but not great.
Then I started my drive south for the winter. I was wearing my contacts again and should have been seeing great. But I wasn’t. Everything in the distance was a bit blurry. I was having trouble reading signs. Objects in the distance on the side of the road that I thought were shrubs turned out to be cows. Oops.
What really confused me, though, is that when I wore my sunglasses and looked through the reading lenses at the bottom of the glasses, I could see distance better. That wasn’t right. I should see distance worse. Sure enough, when I put my readers on, I could see distance better than without them.
So when I got to Arizona, I made an appointment at the same eye center I’d visited the year before, which is the same one I’d used when I lived in Arizona. After the usual eye health check up, I told the doctor what I’d noticed. He didn’t seem terribly surprised. We went through the usual exercise with the machine and eye chart to figure out what my prescription should be. The result: -5.50/-5.75.
My far vision had greatly improved over the past year.
He fetched some sample lenses and I popped in a pair. It was amazing. I could see perfectly again.
But what was even more amazing was that my close vision was also somewhat improved. Although I’d still need readers for small print, I could see good enough for most reading in good light. The doctor confirmed this: instead of +2.50 for readers, I could now use +2.00 readers.
I left the doctor’s office looking around me like a blind person who has just been given sight. I was drinking in everything I saw. The detail amazed me.
Needless to say, it really made my day.
The question both the doctor and I have is why my vision might have improved. He says that vision is often tied in with blood sugar levels and asked if I’d had any blood work done lately. I told him I had, about a month before, and that the doctor had given me a clean bill of health. He said that high sugar levels usually cause vision to get worse, not better. So now I’m wondering if I had high sugar levels last year when tested and they’d come back down gradually since then.
But I have to admit that I honestly don’t care. As long as I can see as clearly as I do now, I’m happy.
On Saturday, I treated myself to a new pair of good quality readers. On Sunday, I ordered two new pairs of bifocals, one of which includes snap-on sunglass lenses. For those interested in saving money on glasses, do check out Zenni Optical; I ordered two pairs of glasses for 1/4 of the price of one pair at Walmart Vision Center. You can’t beat that.
