Re: Problems With Base Curve of Lenses
Posted on May 25, 2009, 3:03 pm by Dr. Virginia Donati
The last time I got a new pair of glasses, I used the same prescription and I was not able to get used to the glasses. Everything looked curved at the edges.
My optometrist suggested that the "base curve" needed to be the same as my old glasses. That solved the problem.
No am I getting another new pair of glasses and they made the base curve the same, but said that it was effectively changed when it was put into the frames. They adjusted the frames to restore it, but I still can't stand to wear the glasses. .
When I look at the computer I see an effect like the page is bulging towards me in places as my eye scans down the page.
My question: should a good optician be able to get this right the first time by using some objective comparison with my old glasses? Should I be asked to go home and try them and go back 2 or 3 or more times to get it right? I find it too hard to try to describe what I am seeing.
Dr. Virginia Donati's response:
I understand your description, and yes it does indeed sound like a base curve issue. It would seem to me that the problem you are having is due to the fact that the base curve of the frame you have selected for your new glasses is different from that in your old ones. That is the reason why the base curve of your lenses were “effectively changed” when they were put into the frame. Some frame adjustment may help to improve the symptoms, but in the end you may just have to select a new frame that would allow the curve of the lenses to remain constant. Make sure when you select your next frame that you tell them you are very sensitive to base curve changes.
