While prolonged use of a computer is associated with eye strain, the irritation normally occurs as a result of muscle fatigue (tiring of the small orbital muscles which articulate the eye, and the ciliary muscles which govern focus by altering the shape of the eye's lens). Unlike when viewing television or a cinema screen, use of a computer entails proximity to the visual device, and the need to focus intently upon parts of it (in order to read, for instance). Just like reading a book, long periods of intent staring can tire the eyes. While using a computer, we also tend to blink less often which can lead to dehydration and irritation of the eye's surface; blinking serves the function of cleaning and moistening.
The eye itself may be irritated, but the optic nerve is not physically influenced by this.

What are causes of optic atrophy?
DefinitionOptic nerve atrophy is tissue death of the nerve that carries the information regarding sight from the eye to the brain.Alternative NamesSecond cranial nerve atrophyCauses, incidence, and risk factorsThere are many unrelated causes of optic atrophy. The most common cause is poor blood flow, called ischemic optic neuropathy, which most often affects the elderly. The optic nerve can also be damaged by shock, various toxic substances, radiation, and trauma.Various eye diseases, most commonly glaucoma, can also cause optic nerve atrophy. In addition, the condition can be caused by diseases of the brain and central nervous system, such as cranial arteritis (sometimes called temporal arteritis), multiple sclerosis, brain tumor, and stroke.There are also several rare forms of hereditary optic nerve atrophy that affect children and young adults.SymptomsOptic nerve atrophy causes dimming of vision and reduction of the field of vision. The ability to see fine detail will also be lost. The pupil reaction to light will diminish and may eventually be completely lost.Signs and testsOptic nerve atrophy can be readily detected on complete examination of the eyes. Seeking the cause may require a complete physical examination and specific tests.TreatmentOnce it has occurred, damage from optic nerve atrophy cannot be reversed. The underlying disease must be found and treated, if possible, to prevent further loss.Expectations (prognosis)Vision lost to optic nerve atrophy cannot be recovered. If the cause can be identified and controlled, further visual loss progressing to blindness may be prevented.ComplicationsComplications will be related to the disease that causes the atrophy.Calling your health care providerPatients with optic nerve atrophy will be closely monitored by an ophthalmologist with experience in neuro-ophthalmology. Any change in vision should be reported urgently.PreventionMany causes of optic nerve atrophy cannot be prevented. Facial injuries can be prevented by standard safety precautions. Most such injuries are related to motor vehicle accidents and can be prevented by seat belt use.Methanol is the most common toxin causing optic nerve atrophy. It can be found in home-brewed alcohol. Home-brewed alcohol and forms of alcohol not intended for drinking should never be consumed.
