Dr. Christopher's Herbal Eyebright Formula is excellent for brightening and healing the eyes, and it is known to remove the cataracts and heavy film from the eyes. A cataract is a cloudiness in the lens of the eye caused by damage to the protein of the lens. This damage impairs vision. Most people who live long enough will develop cataracts. Cataracts are more likely to occur in those who smoke, have diabetes, or are exposed to excessive sunlight. All of these factors lead to oxidative damage. Oxidative damage to the lens of the eye appears to cause cataracts in animals and people.

Cataracts usually develop slowly without any pain or redness of the eye. The most common symptoms of a cataract are fuzzy or blurred vision, increasing need for light when reading or doing other close work, visual disturbances caused by bright lights (sunlight, car headlights), faded color perception, poor night vision, and frequent need to change eyeglass or contact lens prescriptions. A cataract will not spread from one eye to the other, although many people develop cataracts in both eyes.
