"We found people consume green leafy vegetables, has a risk of 20 to 30 percent less likely to develop glaucoma," said study leader Kang Jae. Kang is an assistant professor of medicine at Brigham and Women's Hospital and Harvard Medical School in Boston.
Glaucoma is an eye condition that occurs because of the increased amount of fluid in the front of the eye, causing pressure on the eye and damages the optic nerve. Glaucoma can lead to vision loss, according to the US National Eye Institute.
Although the study found an association between green leafy vegetables with a reduced risk of glaucoma, the relationship is not causal relationships.
Tim Kang examined data on nearly 64,000 participants of the Nurses' Health Study from 1984 to 2012, and more than 41,000 participants in the Health Professionals Follow-up Study from 1986 to 2014. The male and female participants aged 40 years and over.
