- Also known as nearsightedness
- Caused by the eyeball being too long
- The eye focuses the images in front of the retina, instead of on the retina
- Can be corrected with a concave lens, to scatter light before it hits the lens and allow it to be focused onto the retina

Accommodation is the process where ciliary muscles contract to help the lens focus on an image. The lens rounds and flattens to adjust to the distance between the eye and object.
- The lens rounds to focus on near objects
- The lnes flattens to focus on far objects
