Sleeping with the head elevated about 20 degrees helps to decrease intraocular pressure, or pressure inside the eye, which may help prevent or control glaucoma, reports All About Vision. Lower pressure occurs in both glaucoma sufferers and non-sufferers.
The best way to prevent glaucoma is to get regular eye care, Mayo Clinic says. This means having a comprehensive eye exam every three to five years after the age of 40 and annually after 60 years of age. People who are at higher risk for the disease need more frequent evaluations. For instance, African-Americans should start having glaucoma screening exams between the ages of 20 and 39, Mayo Clinic states.
It is important to wear sunglasses outdoors and protective goggles when working with power tools or playing racket sports, explains Mayo Clinic. Additionally, regular exercise may help prevent glaucoma by lowering blood pressure and pressure within the eye, the Glaucoma Research Foundation reports.
Glaucoma is the name for a group of eye conditions that cause damage to the optic nerve, notes Mayo Clinic. The most common type, primary open-angle glaucoma, usually produces no symptoms except gradual vision loss. By contrast, the less common, acute angle-closure glaucoma causes sudden eye pain accompanied by nausea and vomiting, sudden visual disturbances, eye redness, blurred vision and halos around lights.
