Tunnel vision can be caused by any type of damage to the optic nerve, to the retina of the eye, or to areas in the brain responsible for processing of visual input.

Loss of peripheral vision may be a symptom of some of the conditions that cause a generalized loss of vision. Loss of peripheral vision can mean optic nerve damage, glaucoma or optic atrophy. If the eye is red and irritated all the time, you should see an ophthalmologist, because many diseases are responsible for these symptoms - from allergies to severe infections (which untreated can lead to blindness) to the attack of glaucoma.
