Many people mistakenly believe that loss of vision is an inevitable part of aging. It is indisputable that vision usually changes when folks clock age forty, though. But a loss of peripheral vision, or tunnel vision, for instance, could signal something else apart from normal aging. A loss of peripheral or tunnel vision is a symptom of glaucoma. Unfortunately, according to ophthalmologists, half of glaucoma victims are oblivious of their condition. That is because many of glaucoma patients hardly experience early warning signs. Thus, anybody with a blurry vision should go to an eye physicist to receive an evaluation.
Glaucoma damages the optic nerve and is usually due to a lot of pressure in the eye. Having a tunnel vision or experiencing a sudden loss of vision in one eye could be a symptom of a blood flow issue in one eye. It is advisable to go to an ophthalmologist to investigate the source of the problem.
