Presbyopia and glasses for presbyopes
For anyone who would like to understand more about presbyopia and the different types of eyeglasses now available for presbyopes, we have prepared two brief, easy-to-read, illustrated "white papers."
We have written these for a general (non-technical) audience. They are intended to provide essential background information for anyone experiencing (or about to experience) presbyopia -- whether or not they have any interest in Superfocus.
These are both PDF documents that are quick and easy to download to read on your screen or print out on your printer.
Nearsightedness, Farsightedness, Astigmatism, and Presbyopia
Explains each condition, how you correct for it, and how different people experience presbyopia differently.
Eyeglasses for Presbyopes
Tells you what to expect as you age, and explains how each of the options work:
- Multiple pairs of glasses
- Bifocals and trifocals
- New electronically switchable progressives
- Superfocus glasses
