Near vision is the vision required to focus on objects less than 2 feet (60cms) from the eye[1].

As an object moves toward the eye, the eye must increase its optical power to keep the image in focus on the retina. If the power of the cornea and lens is insufficient, as in hyperopia, the image will appear blurred.

The [[cilary muscles] in the eye are used to increase the convexity of the eye to aid in near vision.
