What would a person do who needs prescription glasses? Put me there with ±0 glasses, and I’d be just a threat to the environment, because I had a hard time to know where I’m roughly pointing that thing…
Prescription glasses don’t magnify stuff. Those lens can correct for short sightedness, astigmatism etc, but they’re the exact same lens you find in eyeglasses, what I meant was you can’t put optics on it so it works like a 2x scope.
Well, then I guess they wouldn’t be allowed to wear them backwards.
Glasses actually make everything we see smaller, though the effect is lessened the closer the glasses are to the correct distance from our eyes. And the reason glasses change the perceived size of the wearers’ eyes is because they specifically are bending light to change how it hits our eyes.
If the glasses are for someone who is farsighted, they make their eyes look bigger, if they are to correct nearsightedness, they make the eyes look smaller.
And actually, despite what I say in my first sentence, they don’t even make stuff bigger when you wear them backwards. That effect is limited to the distance eyes are away from the lenses normally, beyond that things are actually still smaller even when looking through them backwards. How much smaller depends on how far they are from your eye.
Eyeglasses unblur the world to those who need them, but there’s no magnification.
Look through binoculars and things look a lot closer because of the magnification. But you can also make it look blurry if you turn the adjustment the wrong way.

Lose.

If they don’t magnify why do they make people’s eyes look bigger

Eyeglasses vs binoculars.
