Dosage
Instill two drops in each eye twice per day, or as directed by a qualified health care practitioner. Lean head back and look up. With clean fingers, pull your eyelids gently open. Bring the nozzle of the bottle closer to your eye. Use a mirror to help you if needed. Press slightly on the bottle to release one drop at a time. Do not blink or reopen the eye for 60 seconds. Repeat this procedure if a second drop is used. 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.

Misshapen proteins accumulate across the entire structure of the eye with "normal" aging, interfering with visual functioning. AGEs, in particular, play a major role in the universal age-related loss of eye structure and function, as well as in the more specific degenerative diseases of the aging eye, such as cataracts, glaucoma, and age-related macular degeneration (AMD)
Delivering Carnosine directly to the eye itself, then, would be predicted to be the ideal real-world test case for the test-tube finding that Carnosine can protect against and perhaps even actually undo the damage wrought by glycation and other protein-warping mechanisms of aging. New human trials have shown that topical Carnosine delivers on this promise
In an open study protocol, scientists gave Carnosine supplements to patients in late middle age who had varying degrees of visual impairment, but no symptomatic cataracts. Over the course of two to six months, the scientists observed that the use of topical Carnosine supplementation "appears to alleviate eye tiredness and ... obviously improve eyesight, giving more clear vision." Users found that topical Carnosine "could brighten and relax their eyes." The improvements were statistically significant.
In clinical studies involving 109 patients, these scientists found Carnosine effective in cases of primary and secondary corneal dystrophy, corneal erosions, trophic keratitis, and bullous keratopathy, as well as corneal ulcerations and other damage wrought on the cornea by viral and bacterial infections. The Russian government accordingly approved topical Carnosine supplementation for these uses as early as 1997
Instead of using Carnosine itself, more recent trials have used N-acetyl-L-Carnosine, a metabolite of Carnosine, which the body slowly converts back into free Carnosine, allowing for slower, more thorough delivery of free Carnosine into the eye's tissues and access to areas of the eye where Carnosine itself cannot penetrate.
In a randomized, double-blind, placebo-controlled study, scientists first evaluated the baseline state of cataract victims' eyes. The scientists then randomly handed out either topical N-Acetyl-L-Carnosine supplements (as a 1% solution) or an identical-looking placebo solution. A third group of cataract patients received no eye drops at all.
After just six months, ninety percent of the eyes of people supplementing with N-Acetyl-L-Carnosine eye drops saw their visual acuity improve, with the strength of the effect ranging from a modest gain to a full 100% recovery. In the same period, only 5.7 percent of the eyes of people using the stand-in eye drops were judged to have improved visual acuity, while over a third (34.7%) suffered a worsening of acuity, and most (60%) simply retained the same impaired vision with which they had begun the study. In a two-year extension, N-Acetyl-L-Carnosine eye drop users were shown to maintain their improved vision, while the eyesight of those not receiving the supplement continues to deteriorate.
Cautions:
To avoid contamination, do not touch tip of the container to your eyes or any other surface. Replace the cap immediately after using. Open only one container of solution at a time. Do not allow other people to use your container. Once open, discard container and any contents after 30 days. Do not heat beyond room temperature; keep the extra container in the box away from light, especially sunlight. Do not use if seal is broken or if solution changes colour or becomes cloudy. Not recommended for children under the age of 12. Application may cause temporary irritation of the eye. If the eye tissue becomes more inflamed, red, irritated or uncomfortable after using this product, or if the condition worsens or persists for more than 72 hours, discontinue use and consult a physician. Keep this and all drugs out of the reach of children. Use before expiration date marked on container.
What Causes Vision Loss?
The eye is a very important sensory organ, which is shown by the fact that a large area of our brain is committed to taking in and understanding visual information. Up to 70% of all of the sensory receptors in the body are in the eyes. Problems with the eyes become more common as we age.
There two main causes of degenerative eye conditions:
Free radical damage
Decreased blood flow to the eye
- Free radicals are unstable molecules that in their bid to become more stable must bump into healthy cells and cause damage. This can cause cell death, alterations in genetic material and autoimmune reactions to damaged cells. Food, water and ultraviolet radiation from the sun are the major contributors of free radicals that build up in the eye.
The eyes reflect the overall health of the body. The vessels on the back of the eyeball are very small and fragile. Changes in them are often the first sign of cardiovascular diseases such as hypertension and atherosclerosis. These conditions lead to decreased blood flow to the retina. Lack of oxygen and an accumulation of waste products eventually compromises vision.
Poor diet, environmental toxins, medications and stress all decrease the body's ability to neutralize free radicals and maintain healthy vessels. This can result in eye degeneration, occurring in cataracts, macular degeneration, and glaucoma.
Who Needs to Take Eye Supplements?
What would we do without our vision? Just about everyone should be concerned abouteye health. Because damage from UV light from the sun is a major cause of vision loss, most everyone should use antioxidant supplements specific for the eyes. The vision loss we experience as we age is only a matter of degree; if we live long enough, we all experience it.
