What Is Myopia?
Myopia is a refractive condition that causes blurry vision in the distance. Near vision is generally unaffected. For example, someone with myopia may not be able to recognize faces far away, but will have no trouble if a person is standing in front of them.
Myopia is usually caused by a cornea (front surface of the eye) that is too steep or an eye that is too long, resulting in the image being focused in front of the retina instead of on it.
