So regarding your last sentence, yes we are incentivised ofc but this is where I defend optometry
Your eye development is mostly complete when you’re 8 years old and there is still some change until you’re 18 or so. So no matter what you do really, the trajectory of your vision is essentially set in stone
Furthermore glasses aren’t like a drug or a crutch.
They aren’t like a drug because the prescription itself does not reflect the quality of your vision. It reflects the quality of your vision vs what’s considered the standard but…—> fundamentally your quality of vision is what you can see with the sharpest prescription given to you —> some people could have a small prescription and terrible vision with or without glasses. For example a blind person’s best vision may be achieved with simply +1.00 but the issue is the health at the back of his eye to where the light is being bent —> Glasses are like a telescope, they bend light onto the part of your eye that is most sensitive to seeing, this is called your macula and it’s the quality of this that’s important. This is basically all determined genetically
They aren’t like a crutch because there’s not a large amount of muscle needed to see. It’s mostly due to the shape and liquids of the eye and once you’re older than 40, the few muscles involved start to wane more and more anyways. You wouldn’t miscorrect a telescope to protect the magnification inside and likewise you should wear a fully corrected prescription. The potential protecting of muscle is negligible.
Also some people think glasses make their vision worse but they may not have realised how bad it was before they got them. Even though this sounds salesy I fully stand by it and everything else
The degradation of your near vision in your 40s is called presbyopia.
Some people in their 40s don’t need any glasses because their eyes are NATURALLY a bit short sighted but only a bit so that they don’t need glasses for far away. There are a few other minor exceptions. But once everyone turns 60 and the presbyopia gets worse, basically everyone needs them
