How do glasses work?

I’ll try my best
At the back of our eyes, there are nerves to receive light (what we see).
That light goes through our eyes where there’s a lens (the centermost circle of our eyes). What these lenses do is they take all the light that would otherwise go in a straight line, and bend them, so that they all focus onto one spot on the nerves.
Normal eyes would have normal, properly working lenses, meaning the image/light going into the eyes would be properly focused. But some of us have abnormal ones (too thin, too thick, or damaged in other ways) and so the focus is off (too far backwards, to far forward from the nerves). When this happens, the nerves dont get focused images, so what we see arent focused.
So eye doctors find out how much thinner or thicker it is compared to normal ones and prescribe you with glasses 😀 which are just bigger versions of the little lenses in our eyes. These bigger lenses are curved in whatever way the doctor sees fit and they pre-bend the light rays that would then pass through the abnormal eye lenses. The point is so that the focus goes back onto the nerves.
Hope this helps, ama!
