they focus it

Basically, they bend the light and focus it on a specific spot. In glasses, that spot is on the retina at the back of the eyeball, which then feeds the images to the brain where they are translated. In a camera, it focusses the light on the film. A microscrope focusses the light on the stage (where the glass slide goes) so you can look through the eyepiece and see a magnified view of whatever is on the slide.
It's remarkable, when you think about it, how simple, yet how complex it can be.

They bend it, because light slows down when it enters a medium of different density. And this slowing effect exhibits itself as bending.

They distort the angle og the lights.

They bend it through refraction or reflection to form an image
