Optic Nerve The optic nerve is located in the back of the eye and is also called second cranial nerve and cranial nerve II. the optic nerve is to transfer visual information from the retina to teh vision centres of the brain via electrical impulses. It is made up of ganglionic cells or nerve cells and consists of more than 1 million nerve fibres . Our blind spot is caused by the absence of specialised photosensitive/light-sensitive cells or photoreceptors; the part of the retina where the optic

FREE OPTICS. Free space optics or FSO –Although it only recently and rather suddenly sprang in to public awareness‚ free space optics is not a new idea. It has roots that 90 back over 30 years-to the era before fiber optic cable became the preferred transport medium for high speed communication. FSO technology has been revived to offer high band width last mile connectivity for today’s converged network requirements. 101seminartopics.com FSO ! FREE SPACE OPTICS Free space optics or FSO

The main factor that leads to the damage of optic nerve is elevated pressure in the eye. The optic nerve is the main visual nerve of the eye. It transmits the images we see back to the brain for interpretation. The shape and tone of the eye is maintained by a pressure within the eye‚ which ranges between 8 mm and 22 mm of mercury. When this pressure is too low‚ the eye becomes softer‚ while an elevated pressure causes the eye to become harder. The optic nerve is the most susceptible part of the eye
