Eye Strain Symptoms

Quite often, while sitting in your office, glaring at the computer screen for hours, you must have felt pain in and around the eyes and at times your vision might have gone blurred. This is nothing but eye strain or asthenopia according to an ophthalmologist’s dictionary. The anatomy of an eye comprises of a bunch of six extra-ocular muscles as well as a ciliary muscle located around the lens. A ciliary muscle’s function involves changing the shape of the eye lens during accommodation of light. So, it is in use all the time and when one is engaged in a visually intense task, it causes the ciliary muscle to tighten and consequently cause strain to the eye. At times, eye strain can be a result of specific visual problems, such as uncorrected refraction errors or binocular vision. Common precipitating factors of eye strain include prolonged usage of computer or monitor screen, reading in very dim light or being exposed to extreme brightness. There are several symptoms of eye strain and once you are aware of them, it becomes easy to treat them as well. Read on to know what they are.
