In health circles there has been much recent talk about acid / alkaline imbalance. Let’s see if we can clarify how experts recommend we correct this imbalance.

The problem: Your body functions best when neither too acid nor too alkaline. Unfortunately almost all of us have become acidic due to diet, drinks and stress -- both psychological and from pollution. Acids can build up in body's system causing body's pH to be out of balance.

The effects: According to Dr. Stefan Kuprowsky, “Acid wastes build up in body in form of cholesterol, gallstones, kidney stones, arterial plaque, urates, phosphates and sulfates. These acidic waste products are direct cause of premature aging and onset of chronic disease.” When this occurs, body will restore its optimal pH by depleting certain minerals, such as potassium, calcium and magnesium, from organs and bones. In addition, your immune system may become fatigued from dealing with an excess of acid. Your body then stores acidic wastes in 'hiding places' such as muscles etc. rather than releasing acids into bloodstream. As Dr. Robert Atkins, noted author, health and diet expert, notes: “Just about every condition I can think of, from arthritis to diabetes to cancer, is associated with acidity.” “The countless names of illnesses do not really matter. What does matter is that they all come from same root cause...too much tissue acid waste in body!” Theodore A. Baroody, ND, Ph.D.

What can be done? A vast body of research reveals you can help body neutralize acids in blood and maintain a balanced pH, by taking some simple steps, such as:  Exercise  Avoiding highly acid-forming food and drink.  Drinking right water

Creating color lenses that would truly transform brown eyes into sky blue or emerald green is a very difficult task, but modern color contact lenses can do it. The trick is to select lenses that would work for you.

There are two types of color contacts - enhancement color contacts and opaque color lenses. Enhancers usually come in different shades of blue, green and gray and are designed to make your natural eye color look brighter. They are translucent and create a natural-looking effect. Unfortunately, enhancement color contacts work only for light eyes. Over brown eyes, enhancers would be either completely invisible or create only a very light tint that was not enough to change your color.

Opaque color contacts, on other side, are specially designed for brown eyes. As name suggests, they aren't transparent; only center of lens is clear, so you can still see. Opaque lenses aren't solid color, of course: they simulate natural pattern of a human eye. See comparison of color contacts for dark eyes.

However, not all opaque color contacts do a good job of recreating a natural pattern. Here, I will highlight brands that create a vivid, but natural-looking, effect.
