So age-onset focusing problems are a problem with a weak muscle, rather than congenital problems which are to do with the shape of the eye itself. Correct (genuinely not sure on this point)?
The muscle controlling accomodation is striated muscle, just like the muscles that move your arms and legs.
So why would making it easier for that muscle to focus make it stronger? Seems to me it's like putting a support bandage on an injured leg, all you do is make that muscle weaker and dependant on the bandage.
You don't fix a weak muscle by stopping using it as much or by p[utting a bandage on it. You fix it by physiotherapy and exercising it. Why is it different for an eye?
So how do glasses slow down deterioration? Surely they just compensate for it until the weakness progresses further? I'd imagine if anything they'd speed up the problem.
Always seems to me that people can hold off needing glasses for a long time but once they have them, they need progressively stronger and stronger prescriptions.
And there stands the basis of my optometry conspiracy theory. Put people whose income is soley reliant on the selling of glasses in charge of deciding who needs glasses and you'll find you need glasses. ____________________ “Rule one: Always stick around for one more drink.

I think you are largely correct.
To give you an idea, I had a squint diagnosed aged 2 years old. I was instantly put on a prescription of "eye patches" which I absolutely detested, but ultimately they work by making your "weak" eye do the lion share of the work and I would guess strengthen the associated eye muscle.
I didn't have any other treatment, just patches and glasses. When I was 15 I was told my eyesight was sufficiently good enough that I no longer needed glasses. However I am to expect to suffer after my mid to late thirties.
I am not sure what I had was applicable to old age as I would guess there are different muscular issues within the eye? ____________________ Be careful whose advice you buy, but, be patient with those who supply it.
