Myopia

Myopia, often referred to as nearsightedness, is a common refractive error of the eye where close objects can be seen clearly, but objects farther away appear blurry. This occurs when the eyeball is too long or the cornea (the clear front surface of the eye) is too curved. As a result, light rays entering the eye are focused in front of the retina instead of directly on it, causing distant objects to appear blurred.

The word "myopia" comes from the Greek muōps, from muein, meaning ‘to shut’ and ōps, meaning ‘eye’.

There are numerous studies that have shown higher IQ scores in children with myopia. It is hypothesized that ocular axial length is directly related to cerebral development.
