Sharon Kleyne Finds Caffeine Study Intriguing. Study Suggests Caffeine Helps Dry Eye Sufferers with Genetic Variations in Two Genes.
Sharon Kleyne tells us that dry eye disease affects more than 4 million people age 50 and older in the United States every year. This rampant condition occurs when the eye fails to produce enough tears or when tears are lost from the eye’s surface as a result of excessive evaporation. Unchecked, this condition can lead to more serious eye illness, even blindness.
Nature’s Tears® EyeMist®, developed by Kleyne and her research center at Bio-Logic Aqua® Research Water Life Science®, is currently the only product that supplements dry eye with pure water and nothing else. Kleyne explained that Nature’s Tears® EyeMist® is applied with a personal hand-held humidifying device emitting a pure, pH balanced, 100% Trade Secret tissue culture grade water in a patented micron-size mist. It supplements the eye’s tear film, which is naturally 99 percent water. “With Natures Tears® EyeMist®,” Kleyne said, “tired and irritated eyes are supplemented with pure water. Eye drops may provide some temporary chemical relief,” Kleyne continued, “but they can become addictive and even make the dry eye condition worse.” Why? Because eye drops only trap water on the eye’s tear lens; they do not supplement the tear lens or the moisture (the tears) around it. Nature’s Tears® EyeMist® does supplement both.
Nature may have also provided, for some, another source of relief. According to AsianScientist, Dr. Reiko Arita of the University of Tokyo School of Medicine created a study based on an earlier study that showed that caffeine users had a lower risk of contracting dry eye disease than non-caffeine users. Like the previous study, Arita’s research showed that 13% of caffeine users had dry eye symptoms while 17% of non-caffeine users had dry eye symptoms. Caffeine is known to increase the secretion of saliva and digestive juices.
Arita’s team also analyzed DNA samples of participants. They were looking for two genetic variations known to play a role in metabolizing caffeine. Researchers found that participants with genetic variations in the ADORA2A AND CYP1A2 genes showed greater tear production after caffeine consumption. “If confirmed by more research,” Arita said, “our findings on caffeine should be useful in treating dry eye syndrome.”
