Sharon Kleyne, host of the Sharon Kleyne Hour Power of Water has been researching the dry eye for two decades. On her radio show, since 2007, she has interviewed many of the world's leading dry eye researchers. With dry eye now the number one reason for eye doctor visits in the United States, one of Sharon Kleyne's missions is to educate the public about dry eye prevention and the tear film.
In recent decades, according to Sharon Kleyne, dehydration related health issues (caused by a loss of natural moisture), such as dry eye, dry skin, dry mouth, computer eye strain, contact lens dry eye, eye allergies, adult acne, dermatitis, Sjogren's syndrome and skin and eye cancers, have increased dramatically.
According to one of Sharon Kleyne's show guests, Lasik pioneer Marguerite McDonald, MD, if left untreated, occasional transient dry eye could lead to more chronic dry eye, which for some people is debilitating and life altering. Dry eye can also lead to corneal ulceration, impaired vision and in extreme cases, blindness.
Sharon Kleyne attributes the global increase in dry eye symptoms to multiple factors. Because of global climate change and increasing air pollution worldwide, exposure to dry, stagnant air and polluted humid air have increased. This exposure is dehydrating to the eyes' natural tear film, as is exposure to smoke, dust, wind, extreme heat and cold and other outdoor conditions.
Indoors, forced-air heating and cooling, insulated walls and windows, low humidity and cleaning fluids are also dehydrating to eyes. Other contributing environmental factors may be contact lenses, computers, extreme sports, caffeine and alcohol consumption, certain medications, and drinking too little water each day.
Regardless of the cause (there may also be internal systemic causes), dry eye and eye dehydration occurs when water in the microscopically thin tear film covering the eyes' exposed portions is lost to evaporation, causing an over-concentration of the tear film's electrolyte (salt) content. Dry eye may be experienced as itching, burning, irritation, blurred vision (especially late in the day), eyestrain, drowsiness, headache, allergies, and/or a "grainy" sensation in the eyes.
Though only about 20 to 30 microns (millionths of a meter) thick, the tear film is amazingly complex. Tear film layers include:
Lipid layer - the thin overlying film of fatty oils (over 100 different fats and oils have been identified), that lubricate the eyelid and slow water evaporation from lower layers. Aqueous layer - the middle and thickest layer that is 99% water. The layer also contains electrolytes, beneficial proteins and enzymes, and bacteria-fighting antibodies. Mucin layer - the bottom layer that adheres the tear film to the ocular surface.
Researchers have long known that the simplest and most natural way to soothe dry irritated eyes is to add two-to-five millionths of a liter (micro-liters) of water to the aqueous layer. A commercially viable method of administering water in such minute quantities was discovered in 1999, when Sharon Kleyne's Bio-Logic Aqua Research developed Nature's Tears® EyeMist®, an all-natural application that supplements tear film moisture with an all-natural, ultra-fine, pH balanced (6.49) water mist using a personal, hand-held misting device.
The mist is applied in seconds and is 100% safe, with no discomfort, blurred vision, saline solution, allergenic preservatives or tear film flooding.
