Thanks for your follow up email. I've read your posting. How may I help you?
While you are posing your question, there is an old rule of thumb that one should be cautious when changing base curves. If you can take your new prescription to the same optician that made your older and more comfortable spectacles he will know the base curves of the lens he made for you before, and he should be able to duplicate them in your new glasses. Does that make sense and help?
Since you are not in the active chat room, I'll switch to Q and A and we can follow up there.
Send your follow up when you are ready. I'll get an email and answer.
