David lives in Worcester, UK, and suffers from periphery vision loss due to open angle chronic glaucoma. He has tunnel vision, which is a lack of vision on the horizon, but a relatively strong central vision. His glaucoma may be caused by his high/elevated blood pressure, according to his eye doctor.
