Age is why your eyes got better.
I guess that that is the optimist's view of things!

When you look up from your book that you are reading in the park to the city towers 10 miles away,
your eyes are doing a major job of re-focusing, just as any camera would.
You are born with eyes that have amazing powers to alter their focus.
All of us lose our power to alter focus as we age at a slower or faster rate.
A 5 year-old might have the ability to change focus by a difference of 16 diopters.
Someone who is 100 years old will have almost no ability to change their eye focus.
The ability to change focus is called "amplitude of accommodation".
Here is a nice
chart showing how it decreases with age.
That's why us old folks wear reading glasses!
