Computer vision syndrome. Computer vision syndrome ( CVS) is a condition resulting from focusing the eyes on a computer or other display device for protracted, uninterrupted periods of time and the eye's muscles being unable to recover from the constant tension required to maintain focus on a close object.
This means that the refractive power of the eye matches what is needed to focus parallel rays of light onto the retina.

When an object is located close to the eye, the rays of light from this object no longer approach the eye parallel to each other.
