Carnosine is found naturally in your body, particularly in muscle tissue. It prevents free radicals from attacking the lens of your eye and helps reverse some of the damage that has already been done to the eye by dissolving any abnormal material that has accumulated there. Carnosine is a small molecule composed of the amino acids histidine and alanine and is found in high concentrations in the skeletal muscle, heart muscle, nerve tissue and brain. Carnosine may act as an antioxidant and as a neurotransmitter - a chemical messenger in the nervous system. Carnosine also generates nitric oxide which helps dilate blood vessels. It is recommended that you take a 100mg capsule two or three times a day.

N-acetyl-carnosine is a variant of carnosine and is available in an eye drop form called Re-Vital Eyes. It has been found to be effective in both the prevention and treatment of cataracts It's recommended that you use two drops, three times a day.

Inositol is an essential component of the phospholipids that make up cellular membranes and is found in virtually every cell in the body. Recent research has shown that inositol helps establish healthy cell membranes, which helps facilitate nerve impulses. Inositol is an important component of eye tissue and low levels have been linked to the formation of cataracts. The suggested daily dosage is 500mg to 1,000mg.

Curcumin is a well-known antioxidant. Curcumin is known for its anti-tumor, antioxidant, anti-arthritic, anti-amyloid and anti-inflammatory properties. Curcumin acts as a free radical scavenger and antioxidant, inhibiting lipid peroxidation and oxidative DNA damage. Researchers have discovered that curcumin, taken in conjunction with vitamin E, can significantly reduce the risk of cataracts.

Lutein and zeaxanthin are essential eye nutrients. They protect against the formation of cataracts and also reduce the risk of developing macular degeneration which causes partial loss of vision. Lutein is used in capsule or tablet form, and the dose is up to 20mg a day. Lutein can also be found in bilberry extracts in capsule form, 150mg a day. Lutein helps protect from oxidative stress and high-energy light. Various research studies have shown that a direct relationship exists between lutein intake and pigmentation in the eye. Studies have shown that an increase in macula pigmentation decreases the risk for Age-related Macular Degeneration (AMD).

Zeaxanthin is another essential eye nutrient that helps protect against the formation of cataracts and reduce the risk of developing macular degeneration which causes partial loss of vision. There is evidence of direct relationship between low plasma concentrations of lutein and zeaxanthin and the risk of developing AMD. There is also epidemiological evidence that increasing lutein and zeaxanthin intake lowers the risk of cataract development.

Emblica officinalis is a plant that contains natural chemicals called tannoids, and is most commonly used in the treatment of diabetes. It is a rasayana tonic that promotes longevity, and is especially good for the heart and lungs. Indian researchers have found that tannoids extracted from emblica were able to prevent the formation of cataracts. The scientists believe that this remedy may be particularly beneficial for diabetics sufferering from cataracts. Emblica is said to help reduce specific toxins, such as aldose reductase, which are often present in high amounts in diabetic patients. The fruit is an adaptogen which means it is a food grade, nontoxic herb that normalizes body function, balances the neuroendocrine system and improves immunity. The recommended dosage is 250mg a day.
