Is diopter a lot?

The optical power of a healthy human eye is about 40 diopters, meaning the ability to focus on an object or image 1/40 of a meter from the eye. The eye of a typical young person can adjust an additional 20 diopters. By age 25 this focusing flexibility is usually reduced to about 10 diopters.
