It’s more common than you might realize, and it can be deadly. You’ve been on the road for three days straight, with not enough sleep, and the air-conditioner and diesel exhaust blasting your face and eyes. After a while, your lips and face get chapped, your neck and shoulders feel stiff, and your eyelids become so heavy you have to stop and grab some coffee. Even then, your eyes may continue to feel tired and burning. Because you’re on a tight schedule, you press on even though your eyes continue to bother you and you know you’re becoming a road hazard. There often just isn’t time, on the road, to adequately protect your eyes.
As you are probably aware, there are several things drivers can do to prevent or relieve tired, strained, irritated “Trucker’s Eyes” on a long distance trip. You’ll be pleased to learn that not all of them involve coffee or eyedrops, either. Bio-Logic Aqua Technologies Biomedical Research has developed a wealth of new information about caring for eyes and skin – the result of a decade of research into dry air and eye moisture. Even if you don’t follow these recommendations to the letter, you never know when the information might come in handy. It might even prevent an accident.
Much of the discomfort that truckers experience while driving comes from dehydration (drying out) of the eyes, skin (especially the facial skin), and breathing passages. Alleviate the dryness and many of the the symptoms go away!
Several environmental factors in the typical truck cabin can combine to cause a slight increase in the rate of moisture (water) evaporation from the TEAR FILM covering the eyes’ exposed surfaces. The tear film is amazingly complex even though it is only about five microns (millionths of a meter) thick. It doesn’t take much evaporation to cause problems. The tear film consists of:
Lipid layer. This topmost layer is comprised of a very thin film of fatty oil that lubricates the eyelid and slows moisture evaporation from the lower layers.
Aqueous layer. The middle and thickest layer contains the vast majority of the tear film's moisture. This is where most moisture loss occurs. The layer also contains electrolytes, proteins and bacteria-fighting antibodies. It provides oxygenated water to allow the cornea to breathe.
Mucin layer. This bottom layer glues the tear film to the optical surface.
The most physically irritating result of tear film moisture loss is an over-concentration of electrolyte (salt) and proteins in the aqueous layer. The results are itching, burning, eye-strain, fatigue and other symptoms. Lack of adequate tear film moisture is called, "dry eye," "dry irritated eyes," or "trucker's dry eye."
Soothing dry irritated eyes is a simple and logical procedure: Simply add moisture to the tear film! However, over the past 110 years of medical research, this has proved more easily said than done. While traditional formulated eyedrops can be beneficial (mostly as a moisture sealer), they are difficult to apply and not always effective. And you need to pull your vehicle off the road to apply them! Also, the chemicals and preservatives in eyedrops can cause an allergic reaction. That’s why it says on the label not to use eyedrops more than three or four times a day.
The primary drawback to eyedrops is that instead of working naturally to augment and replenish tear film moisture, because of the large size of the drops (up to ten times the entire tear film volume), they can flood and wash away the tear film, replacing it with artificial chemicals. The protective antibodies that fight bacteria are also washed away.
The best way to keep eyes moist is to mist with Nature’s Tears EyeMist whenever discomfort is felt. This unique moisture-mist provides the correct pH balance, mineral content and osmolarity to penetrate to the tear film’s aqueous layer in just the right amount –without flooding. Because the product is an all-natural mist, there are none of the drawbacks to conventional eye drops. Best of all, you can apply it while driving!
Even if you use eyedrops, they will become more effective as a moisture sealer (to help decrease tear film evaporation), if you apply Nature’s Tears EyeMist first. Because Nature’s Tears EyeMist has no dosage limit, you may also apply the mist between eyedrop applications—whenever eye discomfort is felt and/or as a preventative before you feel the discomfort.¨ Always keep Nature’s Tears EyeMist in your glove compartment! ¨ Apply Nature’s Tears EyeMist three-to-four times a day, or whenever eye discomfort is felt. ¨ A one-second “Just-a-Mist™ sweep across the face instantly replenishes tear film moisture…naturally, easily, and in just the right amount. ¨ And remember: Nature’s Tears EyeMist cannot be over-used.
Is another Bio-Logic Aqua product, that can be a helpful addition to your glove compartment or first-aid kit. Use it to cleanse cuts and abrasions or to immediately wash off gasoline, or other irritating chemicals, from your skin or eyes. Can lessen chemical burns.
