Glaucoma is an eye disease caused by excess pressure in the eye due to poor circulation of eye fluids. If left untreated, the pressure could damage the optic nerve and cause permanent blindness; in fact, it is the second most common reason for blindness in the world.
Most of the risk factors for glaucoma, such as age and race, are out of your control. However, there are a few things you can do to minimize your risk:
Make smarter decisions when eating. Cutting down on trans fats helps lower high blood pressure. This means reducing the amount of fried foods and processed foods in your diet.
Increase the amount of fish, particularly ones rich in omega-3 fatty acids like salmon— in your diet. Blueberries and cranberries are rich in bioflavonoids, which strengthen the capillaries in the eyes, allowing more essential nutrients to reach it.
Regular exercise has been proven to be effective in lowering your intraocular pressure (IOP). You do not need to work out in the gym like a bodybuilder to achieve this effect though. Moderate exercise like jogging three times a week is enough to lower your IOP.
Take note that you can still develop glaucoma despite following the tips above, especially if you have a family history of the disease. With that in mind, it is best that you see an ophthalmologist for a thorough eye exam every year once you reach the age of 40.
