Astigmatism
An irregular eye surface skews light so it can't focus properly.

Bifocal Contacts
These lenses stay in place when your eye moves, so your pupil can find the near or distance zone as needed.

Lenses
Eyeglasses and contact lenses bend light so it focuses right where it should.

How the eye bends light determines how well we see.

Myopia (Nearsightedness)
The longer shape of the myopic eyeball forces light to converge before it reaches the retina.

Pupil Dilation
Here's how the pupil opens and closes in light and dark conditions, to control how much light comes into the eye.
