As of 2015, there is no medically proven natural remedy to cure glaucoma, according to the Glaucoma Research Foundation. Glaucoma is an incurable eye disease that results in vision loss and blindness, usually as a result of prolonged pressure on the optic nerve.
Medications and surgery are the only proven methods for lowering pressure inside the eye, or intraocular pressure, and thus prevent blindness. People with glaucoma should never drink more than a quart of fluids at once, according to Mayo Clinic. Sipping fluids throughout the day prevents fluctuations in intraocular pressure. Regular exercise and good nutrition are healthy lifestyle measures that may help control intraocular pressure.
