- A number of changes occur in the eye as you grow older, but most experts agree that a hardening of your lens causes presbyopia.
- The theory is that presbyopia occurs because the lens becomes too large, not too hard but too large.

- Example sentences
- If you had good, uncorrected vision before becoming presbyopic, you may be able to use nonprescription, over-the-counter reading glasses.
- Those who are farsighted and prematurely presbyopic may indeed be candidates for this procedure but not most aviators.
- I spend way too much time online, reading most of my news on a computer where my presbyopic vision is aided by bright contrast and the ability to make fonts larger.
Late 18th century: modern Latin, from Greek presbus 'old man' + ōps, ōp- 'eye'.
