focusing muscles are used for close up but nnot distance-can you explain please?

The ciliary muscle-magnitude decreases with age

the less you use it or the more you use it. Its how all muscles work

Not saying aging isn't a factor.

'éxercising' a muscle isn't all about one thing. Range, being able to relax. Many of us have muscles that never fully relax. Training with short biceps curls trains your biceps to be short.

Always looking close up and rarely using distance (which I'm guessing you are saying is done by the muscle relaxing). Why is this muscle so different?

I think every athlete out there if not every person can tell you some tight areas they have. Most will be from habitual use, posture/training etc

Why are the eyes so different?

You exercise a muscle so has a full range. So that its long and resilient. So that it can relax. As well as getting stronger, more powerful etc

So these muscles controle focus one way but not the other? Or do I miss understand? aAre there different muscles for far and close?

Talking generals here not someone with out an eye or this specific problem.

Again-what is taught (if nothing else) is one school of thought. There is rarely only ONE way.

The more I know about the body the more it makes sense.

use it and use it right or loose it or train it wrong.

train right and you can correct most things to some degree if nothing more.

wear a cast for 2 months and see what happens

wear a different prescriptions on each eye-do you think they will be the same after a year?? I would bet money on that one.

Regardless what studies are sellected or taught.

Or wear corrective on one side and nothing on the other-say 100 cases. By your logic the eye with nothing should be worse? I place a bet on that one too.

makes sense to me anyway.
