VISUAL OCUITY is an eye drop formula containing as active ingredients the lubricants glycerin (1.0%) and hydroxypropylmethylcellulose (0.3%). VISUAL OCUITY also contains sterile water (opthalmic grade isotonic solution, pH 6.3 to 6.5), N-Acetyl-L-Carnosine (NAC) (1.0%), buffering agents (boric acid, citric acid, and potassium bicarbonate), and purified benzyl alcohol as a preservative. One box contains two (2) large vials (5.0 ml each) of the eye drop solution.


VISUAL OCUITY has been designed to support healthy eye function. A wide range of causes including excessive free radicals, smoke, dust, ultraviolet rays, excessive sugars, drug use, inadequate nutrient levels, and poor blood flow can lead to poor eye health. An eye drop formula containing lubricants and antiglycating agents can help to healthy eye function. Research studies on NAC are discussed below.


N-Acetyl-L-Carnosine (NAC) is a timed release form of the naturally occurring dipeptide L-carnosine—a powerful antioxidant and antiglycating agent. Both in human and animal studies NAC shows remarkable effects in protecting and restoring eye function.

N-Acetyl-L-Carnosine (a natural combination of beta-alanine and L-histidine) acts both as a powerful antioxidant and as an inhibitor of glycation. Glycation results when sugars (e.g., glucose) react with proteins, creating damaging substances known as ‘Advanced Glycation End Products’ (AGEs). This is a process of cross-linking that is characteristic of biological aging.

Dr. Linus Pauling has shown how dietary sugars (especially sucrose) play a prominent role in collagen cross-linking throughout the human body, and that sugars target collagen structures more specifically. High-collagen structures include skin, connective tissues (e.g., ligaments, tendons, and bones), and the cornea and lens of the eye (in crystalline form). He likens the cross-linking process to the tanning of hide, whereby formerly flexible, soft tissues become hard and leathery (and lose their proper internal structure and tensile strength). (See Dr. Pauling’s How To Live Longer and Feel Better, rept. 2006.)

Other scientists and researchers liken reduced vision to the clouding of egg white during pan frying, as the proteins in the albumen become glycated during the cooking process. In living organisms including humans, such ‘tanning’ or ‘clouding’ represents an interference (i.e., a fundamental loss) in the structure and function of the organs and/or tissues involved in the glycation process.

While glycation and creation of AGEs are considered perfectly ‘normal’ in aging, these processes may become accelerated by free radicals in the environment (e.g., oxidant chemicals), as well as by dietary factors (endogenous and exogenous). Conversely, factors such an increased intake of antioxidants or reduction of substances (e.g., sugars) that participate in cross-linking of collagen fibers can help reduce rates of glycation and generation of AGEs.

Dr. Pauling, for example, shows that high levels of vitamin C protect collagen fibers during exposure to glycating agents, not only because of elevated antioxidant activity in vivo (i.e., increased free-radical quenching capacity in the body) but also because Vitamin C is needed for collagen formation and synthesis—one of the primary reasons Dr. Pauling emphasizes Vitamin C in his nutritional supplement regimens.

This means Vitamin C directy counteracts the glycating action of sugars on collagen tissues, hindering the accelerated aging that might otherwise occur as a result of glycation. Vitamin C is thereby a prime example of a natural substance that protects proteins from glycation (and demonstrates the effectiveness of what Dr. Pauling terms ‘orthomolecular’ medicine).

While L-Carnosine utilizes a different mode of action than Vitamin C, and is unique in its capacity as a topical antiglycating agent, it is likewise a natural substance that works with the body to improve health.

Science understands therefore that it is largely because the human body is built of proteins (e.g., collagen) that any substances (whether food substances, chemicals, environmental oxidants, etc.) that induce glycation (and deterioration of proteins) can result in harmful effects to our biological systems, including accelerated aging, and processes leading to degenerative disease and decreased lifespan. This biochemical model affirms the free-radical theory of aging.

The scientific establishment’s acceptance of the free-radical theory of aging in turn suggests that for increased health it is beneficial to maximize extant antioxidant systems in the body (e.g., via supplying proper nutrition) and to use current knowledge regarding, for example, oxidation and glycation processes to build health and retard accelerated aging using natural antioxidants and glycation inhibitors that are most easily recognized by the body.

Recent studies indicate that N-Acetyl-L-Carnosine (NAC) is an extremely effective antiglycating agent. The L-carnosine molecule effectively competes with proteins for binding sites on sugar molecules, consequently thwarting glycation and subsequent damage to proteins. Research also suggests that L-carnosine binds to and modifies existing AGEs supporting the body’s efforts to remove deleterious or toxic glycation end products.

 only contains the highest-quality ingredients. Active: Glycerin (lubricant) 1.0%, hydroxypropylmethylcellulose (lubricant) 0.3%. Inactive: Sterile water (opthalmic grade isotonic solution, pH 6.3 to 6.5, N-Acetyl-Carnosine (NAC) 1.0%, buffering agents (boric acid, citric acid, potassium bicarbonate), and purified benzyl alcohol (preservative).

DIRECTIONS: Place 1 or 2 drops in each eye 1–4 times per day, or use as directed by a health care professional. Please carefully read the enclosed product insert. For the proper installation of drops, lean head back and look up. Do not blink or reopen the eye for 60 seconds. If a second drop is used, repeat this process. Closing the eye allows each drop to be absorbed into the eye tissue. Blinking, even one or two times, will pump most of the solution out of the eye. If you have neck problems, lie down or use a tilt-back chair.
