I'm with Tim here. A lot of deterioration of sight is through lack of
use of the accommodation muscles. While the lens does harden my sight
deteriorate most when sedentary and focussed onto a screen with a
blank wall behind. Since then I choose to sit where if I look over a
monitor I have a distant view.

Err, someone with perfect vision will only choose to have reading specs
when it becomes impossible to focus close enough without.

Err if you can't focus close enough you haven't got perfect vision.

Err, no older person ever has, bert. But may well have had when younger.

The worst killer for accommodation is varifocal lenses. The eye
muscles become very lazy.

Why would you get varifocals if you still could accommodate OK?

Oh dear.

You don't understand much about your own eyes, do you?

Well I've lived with them a long time so I Know them pretty well.

Apparently not.
