Moisture Is Water!
Creams and lotions are not moisture, even when labeled as “moisturizers”. Moisture can certainly contain substances other than water, but as water diffuses into moisture, the dissolved minerals, contaminants, and pollutants, can remain suspended in the minute moisture droplets.
The Amazing Tear Film.
The ocular tear film the covers the exposed portion of the eye and is only four or five microns thick. When eyes become dry, the ultimate cause is usually moisture depletion in the tear film’s middle layer. This depletion can total no more than two to five nanoliters but those barely measurable quantities can make a huge difference. Replace those nanoliters and your eyes will feel much more comfortable.
The Eye Drop Dilemma.
How do you get two to five nanoliters of into the aqueous layer? You could use a very tiny eyedropper but it would be needle thin and not practical for safety reasons. The typical commercial eyedropper is much larger and blunt-ended. Its drops, however, contain ten to 40 times the volume of the entire tear film. Drops that large flood the tear film and wash away the overlying lipid (oil) layer, whose purpose is to slow moisture evaporation from the aqueous layer. Disrupting the lipid layer can make dry eyes even dryer.
The Mist Solution.
The “Mist Solution,” discovered by Nature’s Tears EyeMist, utilizes an ultra-fine mist instead of drops. The micron-droplets penetrate the overlying lipid layer much like vinegar penetrates salad oil: the oil parts, the water enters and the oil then reseals.
Using the right water is critical. Water for the eyes must be sterile and free from contaminants and pollution. It must be mostly free from salt, heavy metals, artificial formulations and potentially allergenic preservatives. It must contain minute quantities of beneficial minerals such as silicon, calcium and potassium. And it must have a pH (acid/alkaline) balance that is compatible with the tear film’s pH.
A word about salt:
Everyone knows that tears are salty, but exactly how salty they are can be critical. When the aqueous layer loses water to evaporation, the salt remains. It is this over-concentration of salt that causes discomfort. Discomfort is alleviated only when the salt concentration is diluted to normal levels. Adding salt to dry irritated eyes (salt is an ingredient in nearly all artificial tear products), cannot not possibly dilute the aqueous layer’s salt.
Nature’s Tears EyeMist – the First and Only!
Nature’s Tears EyeMist is the first and only product that utilizes a diffusion of ultra-pure, pH compatible water, with a mild and beneficial mineral content, free from preservatives and formulated chemicals. The water is “Bio-Logic Aqua tissue-culture grade water.” This unique water is applied to the eyes – using specially designed vaporizing technology – as an ultra-fine mist, to supply needed moisture, in nanoliter quantities, directly to the tear film’s aqueous layer.
