Glaucoma is a chronic condition that affects cells at the back of the eye. It is the leading cause of irreversible blindness worldwide, and is responsible for 1 in 10 cases of serious sight impairment in the UK.
Glaucoma is a common eye condition where the optic nerve becomes damaged. It usually occurs as a result of fluid building up in the front part of the eye, which increases pressure inside the eye. If the condition is left untreated or not treated early enough it can lead to loss of vision.
Drinking hot tea could be linked to a lower risk of having an eye condition that can lead to blindness, research has suggested — although experts say the study does not show that the brew offers any protective effect.
