According to Sharon Kleyne, Founder of Bio-Logic Aqua Research, Inc., dry eye discomfort is increasingly prevalent worldwide due to global climate and temperature change, diet, widespread computer use, air pollution, population growth and “climate controlled” indoor environments. Dry eye discomfort occurs when too much water is lost (usually to evaporation) from the protective natural tear film covering the eye’s exposed portions (the cornea and sclera).
The tear film is 99% water, Sharon Kleyne explains, some of which is obtained by absorption from the air (provided the air is humid and clean). When the tear film loses water, the main symptom is discomfort resulting largely from over-concentration of tear film salt (electrolyte). Normally, tear film salt/electrolyte is diluted by the water (tears contain far less salt than perspiration, which is why perspiration that drips into the eyes causes discomfort).
Dry eye discomfort may be experienced as itching, burning, eyestrain, blurred vision, headache, sleepiness, puffy or water eyes, and/or a “grainy” sensation. In cases of severe chronic dry eye, the discomfort can be debilitating and life changing.
Researchers have long known that the simplest and most natural dry eye relief – to soothe and re-hydrate dry eyes – is to replace the missing tear film water and thereby dilute the salt. The addition of only one-to-two microliters (millionths of a liter) of water per second to the tear film’s middle (“aqueous” or water) layer, should provide sufficient dilution to soothe dry eye discomfort (Mathers, WD, MD, Tear Film and Treatment of Dry Eye Disease, RxSchool, 2005, p. 13).
A method of achieving dry eye relief by applying supplemental water to the tear film’s aqueous layer in minute quantities, was invented by Bio-Logic Aqua Research in 2002 and subsequently marketed as Nature’s Tears
