Glaucoma is the second leading cause of blindness in the world, and belongs to a group of eye diseases that damage your optic nerve, leading to vision loss. In its early stages, glaucoma may produce no symptoms at all, and it’s estimated that half of the more than 4 million Americans with glaucoma do not even realize they have it.[1]

Because the vision loss caused by glaucoma comes on so gradually, it is sometimes called the “silent thief of sight.” Often, it’s not until the disease is at an advanced stage that the related vision loss becomes apparent, and by then your sight may suffer permanent damage.

This is why it’s so important to take steps now to help protect your vision, even if your eyesight is normal. I’ll be discussing exactly what you can do to help prevent and treat glaucoma later in the article, but first here’s a bit of background on this common eye problem.

What Causes Glaucoma?

The underlying causes of glaucoma are not completely understood, but typically the damage it does to your optic nerve is related to increased pressure in your eye. The pressure typically comes from a buildup of pressure from the aqueous humor, the watery fluid that is naturally present in your eyeball.

In a healthy eye, the fluid is regularly drained, however in those with glaucoma the drainage system doesn’t work properly, so the fluid gradually builds up in your eye, causing increased pressure. Over time, the increased pressure causes nerve fibers that are essential to vision to die.

Though less common, glaucoma can also occur when eye pressure is normal. It appears some people’s optic nerves may be sensitive to normal levels of eye pressure, or the glaucoma may be related to problems with blood flow to your eye, which may be caused by atherosclerosis -- the accumulation of plaques in your arteries -- or another circulation problem.

In the most common type of glaucoma, open-angle (chronic) glaucoma, side (peripheral) vision is usually affected first. In the later stages, glaucoma can lead to “tunnel vision,” where you can only see straight ahead, and can eventually lead to blindness. The symptoms are gradual and come on very slowly, so you may not realize your vision is being impacted until much later stages.

About 10 percent of those with glaucoma have what’s called angle-closure (acute) glaucoma, and in these cases a sudden rise in eye pressure can cause:

  • Severe eye pain
  • Blurred vision
  • Sudden visual disturbances
  • Halos around lights
  • Reddening of the eye
  • Nausea and vomiting

This latter form usually requires immediate treatment.

Who is at Risk?

Anyone can get glaucoma, but there are factors that increase your risk:

  • Certain ethnicities: Glaucoma is six to eight times more common in African-Americans than in Caucasians.[2] Mexican-Americans, Asian-Americans and Japanese-Americans are also at an increased risk.
  • Over 60 years old: The risk of glaucoma increases once you are over 60.
  • Chronic diseases: Diabetes, high blood pressure, heart disease and hypothyroidism all increase your risk.
  • Family history: If someone in your family has glaucoma, it may increase your risk.
  • Eye injury and nearsightedness: Eye injuries such as retinal detachment, eye tumors, eye inflammations and eye surgery, as well as nearsightedness, increase your risk.
  • Use of corticosteroids: A prolonged use of these drugs appears to increase your risk, especially corticosteroid eye drops.

Making Sure Glaucoma is Diagnosed Correctly

Ophthalmologists typically rely on a simple "air puff" test to check for high pressure inside your eye. However, if you are getting screened for this disease, please make sure you also have your corneal thickness measured using a relatively newer test called pachmyetry. 

Pachymetry, which measures corneal thickness, may be a more reliable indicator of the pressure inside your eye because the thickness of your cornea can significantly influence the readings on the air puff test.


Conventional Ways Lower Your Eye Pressure

Conventional medicine’s solution to glaucoma is typically drugs or surgery, or a combination of them. Often eye drops are given to glaucoma patients to use for life in an attempt to lower pressure inside of their eyes, but they come with a laundry list of side effects including:

  • Blurred vision
  • Respiratory problems
  • Forgetfulness
  • Lowered heart rate
  • Burning or stinging in the eyes

Surgery also carries with it serious risks, among them an increased risk of cataracts.

Natural Ways to Lower Your Eye Pressure

You do have another option, though, as surprising as it may sound the same lifestyle changes that lower blood pressure typically also work to lower your eye pressure, thereby helping to prevent and even treat glaucoma without a risk of side effects.

The top two steps are:

  1. Lower your insulin levels: As your insulin levels rise, it causes your blood pressure, and possibly also your eye pressure, to increase. In time this can cause your body to become insulin resistant, and studies show insulin resistance -- which is common in people with diabetes, obesity and high blood pressure -- is linked to elevated eye pressure.[3]

Other Tips to Keep Your Vision Healthy


  • Taking an animal-based omega-3 fat supplement. A type of omega-3 fat called docosahexaenoic acid (DHA) may help protect and promote healthy retinal function. DHA is concentrated in your eye's retina and has been found to be particularly useful in preventing macular degeneration, the leading cause of blindness.

Omega-3 fat, including DHA, is found in fish, but I don't recommend eating fish due to the concerns of mercury and other toxins that have been found in fish from oceans, lakes and streams and farm-raised fish. Instead, my most highly recommended source for omega-3 fat is krill oil.



It is important to note that lutein is an oil-soluble nutrient, and if you merely consume the above vegetables without some oil or butter you can't absorb the lutein. So make sure you’re eating some healthy fat along with your veggies,
