There are few things in life more precious than your eyesight. But if you have glaucoma, you could slowly be going blind and not even know it.

Glaucoma is a condition that damages the optic nerve, which connects your eye to your brain. With the most common form of glaucoma, there are almost no warning signs until you’ve already started to lose your vision. That’s why it’s known as “the sneak thief of sight.”

Be Wise About Your Eyes to Prevent Glaucoma

January is Glaucoma Awareness Month, and for many people, it also marks the beginning of a new year for their health insurance benefits.

One of the best ways to prevent glaucoma from stealing your eyesight is to get an annual eye exam. Check your vision benefits — many Independence Blue Cross vision plans offer coverage for one eye exam per benefit year.

Take a closer look at these glaucoma facts to help protect your peepers:

What causes glaucoma?

Open-angle glaucoma is the most common type of glaucoma. Over time, fluid slowly builds up in the front of the eye. If it doesn’t drain properly, eye pressure increases, which can damage the optic nerve. This nerve sends light signals from the eye to the brain. Vision loss caused by glaucoma is not reversible, and there is currently no cure for it.

Are you at risk for developing glaucoma?

People of all ages are at risk for developing glaucoma, even babies, who can be born with it. It’s one of the leading causes of blindness in the United States. Certain people are at higher risk than others, including people who:

  • Have a family history of glaucoma
  • Have high blood pressure or diabetes
  • Are over age 60
  • Are nearsighted (able to see things clearly only if they are close to the eyes)
  • Are African American, Asian, or Hispanic

Since glaucoma can run in families, it’s important to know your family health history. And just like every family is unique, every person’s eyes are different. Your eye shape and how much pressure your optic nerve can withstand are also factors in your risk for developing glaucoma.

How can you prevent glaucoma?

Getting regular dilated eye exams can help prevent glaucoma. This type of exam opens your pupil, which lets the eye doctor examine the optic nerves at the back of your eyes and check the pressures in each eye. Your doctor can help you figure out your personal risk for developing glaucoma and how often you should get checked.

Eat Right to Protect Your Eyesight

Eating a diet rich in vitamins C, E, and A, and antioxidants like zinc is key to helping prevent glaucoma and promote overall eye health. Include these power foods on your daily menu:

  • Oranges, berries, tomatoes, and peppers (vitamin C)
  • Green leafy vegetables like spinach and kale, nuts, seafood, and avocado (vitamin E)
  • Carrots, sweet potatoes, and broccoli (vitamin A)
  • Eggs, whole cereals, and lean meats like chicken (zinc)

In addition to diet, regular exercise can help you maintain a healthy blood pressure and protect your eyes against damage that causes vision loss.

When it comes to your health, it pays to keep your eyes on the prize — years of seeing our beautiful world clearly.

My personal philosophy about health and well-being is to have simple goals and stick to them — whether it’s drinking more water, working in a few extra steps each day, or just making time to unplug. When I’m not busy writing creative content for a variety of audiences, my favorite ways to unwind include enjoying local arts and culture, reading a good book, and watching TV cooking shows.
