Eyesight is a function of compression of the eyeball with infected tissues surrounding the eyeball (typically caused by fungus), and a function of the muscles being in good or bad condition.
You can train any muscle to see good.
But to really see good, what you really need is UVa and UVb light.
Sitting indoors means you don't get any of that.
That's why so many people are myopic (nearsighted).
It's not even the strain of reading a screen for too long. It's a lack of UV light... which also means wearing sunglasses anywhere might worsen your eyesight.
Now the world of glasses and optometry is dedicated to resolving the problem of not seeing good by devising products which do the work for your eye muscles.
A good medical optometrist will prescribe you glasses that are 0,75 to 1,00 diopter weaker than your eyesight is, so your eyes will still have to work to focus.
The typical optician however is not trained to consider this, and when the machine says your eyes are 2,00 diopter, you get 2,00D lenses. Not 1,25D.
That WILL make your eyes worse and lazy over time, and keeps you coming back for new prescriptions. Good for the corporate business. Bad for you.
A secondary problem with the optician is this.
It costs €30 to blow the glass (or plastic these days) into shape following prescription specifications with all the options (every single coating, extra premium thin), no matter how big your glasses are.
The robotic machines are optimised for throughput.
AFAIK there's only one spectacle factory in all of Europe, somewhere in France. That's why it can take weeks for the lenses to show up at the optician who then puts them in your frames.
But the lenses cost €30. The frames cost €5-€20 to manufacture, depending on material, design and tooling costs.
When you buy this premium luxury option, you're not paying €50. You're paying €600.
But what are you gonna do about that. Order from the factory? Can't do. It's a racket.
