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.

vestibulocochlear nerve
What does an optic nerve look like?
The optic nerve is not visible to the naked eye as it is located inside the eye socket. Its appearance can be visualized using specialized medical imaging techniques such as ophthalmoscopy or fundus photography. The optic nerve is a bundle of nerve fibers that connect the eye to the brain, and it has a cylindrical shape with a whitish-pink color.
What is the purpose of an optic fiber?
Fiber Optic is used for telecommunication and computer networking. Fiber optic cables have a much greater bandwidth than metal cables. Data can be transmitted digitally for computer data instead of analogically. There is also a higher bandwidth when using fiber optic.
Where is the blind spot located?
The blind spot is also called the optic nerve head. It is located on the retina, about 15 degrees horizontal from center vision.

The observations include, but are not limited to the retina, blood vessels, and optic nerve. The optic nerve enters the back of the eye and can be checked for swelling or other problems. The blood vessels can be viewed as can the retina.
What are symptoms of optic atrophy?
Optic Atrophy occurs when the optic nerve gets damaged due to shrinkage by the degeneration of the retinal ganglion cell axons and stops carrying impulses from your eye to your brain. One of the most common reasons for the Atrophy (deuteriation) occurs due to poor blood flow and is more common in adults. Optic Atrophy causes multiple vision problems, eventually leading to the patient being blind. What are the causes of Optic Atrophy? Impulses are sent to the brain from the eye through the optic nerve which comprises of nerve fibres. Optic Atrophy occurs when these impulses aren’t able to be sent to the brain due to factors and interferences. These factors include: Poor Blood Flow Glaucoma Anterior Ischemic Optic Neuropathy, otherwise known as a stroke in the Optic Nerve Pressure on the Optic Nerve that is caused by a tumour The Optic Nerve may get swollen due to inflammation caused by Multiple Sclerosis A birth defect Family History What are the symptoms of Optic Atrophy and when should I see a doctor? Symptoms of Optic Atrophy may seem mild in the beginning but it is imperative to visit your doctor at the earliest for any kind of vision problem. Symptoms of Optic Atrophy include: Blurry Vision or reduction in the sharpness of vision Problems identifying colour Problems with Side Vision or Peripheral Vision All vision related issues must be dealt with as soon as symptoms start to appear as they may be a part of bigger health problems. How does my doctor diagnose Optic Atrophy? Optic Atrophy is diagnosed by an ophthalmologist using an op ophthalmoscope. The doctor will examine the optic disc, which is at the back of the eye where the optic nerve enters the eye. If the doctor suspects a tumour, you may be asked to get an MRI Scan. Can Optic Atrophy be treated? Although Modern Medicine does not have a cure for Optic Atrophy, the cure depends on that the cause of the problem is. For instance, if the cause of the Optic Atrophy is an inflammation due to MS or a Tumour, vision might return to normal when the inflammation reduces. For patients with Glaucoma, if Glaucoma is caught early, optic Atrophy can be treated to grow slower which is why it is important to visit your doctor as soon as problems in vision arise.

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.
