Myopia is a disease, not a refractive error. Here's what that means
Myopia is a refractive error (blurred vision at a given distance) that affects about 30% of the world's population. This proportion is increasing so quickly that it ...

Refraction and lenses
It is refraction that makes some objects appear ... Focusing light is important for getting clear images in our eye or in photographs, because images that are not focused appear blurred.
