Part 1: What is Eye Strain

The eye moves around the socket to see. This movement is controlled by six eye (ocular) muscles surrounding the eye. Another muscle of the eye, the ciliary body around the lens, makes adjustments to the lens so we are able to see objects at different distances. Straining of any one of these muscles will cause eye strain.

The ciliary body, the muscle that controls the lens, is the most common muscle of the eye to become fatigued. Focusing on one thing for too long will cause muscle fatigue and eventual eye strain. Another cause is making the ciliary body (which includes the ciliary muscle) constantly work by often looking at objects of varying distances.

Common Symptoms:

1. Headaches
2. Back/neck aches
3. Twitching of muscles surrounding the eye
4. Dry eyes
5. Blurred vision
