Answer 1

Hint: Tunnel vision is the problem of the eyes in which a person loses their peripheral vision. It is a state when field vision of the eye is narrowed down to that point people cannot see sideways without movement of head.

Complete Answer:
- Tunnel vision syndrome is also called peripheral vision loss.
- Tunnel vision is caused by the various factors: Glaucoma, Retinitis pigmentosa, Cataracts, retinal detachment, Ocular migraines, Stroke, Choroideremia, Injury Induced Blood Loss, Hallucinogenic Drugs, and Alcohol Induced Intoxication.

(I) Glaucoma: In glaucoma, the intraocular pressure of the eye is increased and it causes the damage in the optic nerve which leads to vision impairment.
(II) Retinitis pigmentosa: In this eye light sensitive cells rods and cones are damaged and that is why they cause vision impairment.
(III) Cataracts: Accumulation of the protein in the eye.
(IV) Retinal detachment: Retina detach from the eye.
(V) Alcohol Induced Intoxication: Alcohol also affects the vision.

So, the correct answer is tunnel vision is caused by alcohol.

Additional information: Even nowadays with such medical advancements, no treatment is available for full recovery for vision loss. That's the reason why ophthalmologists force on taking good care of your eyes for good eye health and a regular eye exam. This will help doctors diagnose eye problems as soon as possible, making sure to take best treatment of them in due time.

Note: Tunnel vision syndrome occurs by so many different ways, which is temporary as well as permanent. Degenerative eye diseases like glaucoma cause peripheral vision loss permanently, on the other hand conditions like concussion and alcohol abuse lead you to temporary loss of peripheral vision.
