The Natural Solution to Contact Lens Discomfort

Contact lenses, those handy-dandy little vision aids, make the difference for 28 million people between seeing clearly in all directions, or being confined to inconvenient and distorting eyeglasses or worse. With the many choices and technological advances available these days, contact lenses should continue to benefit millions of people who have less-than-perfect vision.

Here’s the catch: While a few contact lens users are able to wear their lenses for days or weeks at a time with no problem, such individuals are the exception. Many people can tolerate contact lenses only for short periods, and many cannot tolerate them at all. Even for those who tolerate them reasonably well, lenses frequently cause discomfort. This article will suggest a way to soothe much of the eye discomfort caused by contact lenses:

The amazing tear film

The main thing to know about contact lenses is that they float on the surface of the delicate and complex tear film that covers the exposed parts of the eyeball, and they rely on the tear film’s moisture (water content) to maintain their pliability, integrity and adherence. The surface tension of the tear film’s moisture against the lenses prevents them from falling out.

The problem is that the most popular types of lenses deplete the tear film’s moisture content and therefore interfere with healthy tear film functioning. Soft lenses, and gas permeable lenses, have been compared to miniature sponges because of the amount of tear film moisture they soak up. Even rigid lenses deplete some tear film moisture. In addition, all lenses, even gas permeable, reduce the amount of oxygen reaching the corneal surface. Rigid lenses restrict oxygen the most, which is one reason they are smaller.

Tear film function and structure

The tear film that covers the exposed optical surface is amazingly complex, considering that it is only about five microns (millionths of a meter) thick. Tear film components:

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.

Dry irritated eyes

When tear film moisture is depleted, the resulting abnormal changes can make the eyes feel uncomfortable. The most physically irritating results of tear film moisture loss are an over-concentration of electrolyte (salt) and proteins in the aqueous layer. Insufficient oxygen in the aqueous layer’s moisture can also cause discomfort. Discomfort can include itching, burning, irritation, eyestrain, headache, etc.

Soothing dry, irritated eyes

Soothing dry, irritated eyes, whether caused by contact lenses, environmental conditions or bodily dehydration from illness or stress, is a simple and logical tear film cross section procedure: Simply add moisture to the tear film! In the past 110 years of medical eye care research, however, this has proved more easily said than done.

One problem has been getting the moisture past the overlying lipid layer. As it turns out, our eyes already know how to accomplish this trick. The tear film is perfectly capable of extracting all the moisture it needs from the humidity in the air, provided the air is reasonably humid (70% at 70 degrees), and the humidity droplets are pure and unpolluted.

However…the standard solution to the problem of dry, irritated eyes has been not humidity but eyedrops. Since eyedrops rely on chemical formulations and eyedroppers, they pose numerous drawbacks. The typical eyedrop is ten times larger than the volume of the tear film. When applied, the drop may flood and wash away the natural tear film, including the evaporation-retarding lipid layer. Despite their complex chemistry, formulated eyedrops invariably lack one thing: The minute quantity of pure, natural, pH-balanced water that is all the tear film really needs.

    Additional drawbacks to eyedrops and wetting agents:

  • You have to remove your contact lenses to apply them.
  • Some people are allergic to the chemicals and preservatives.
  • The eyedropper can cause injury.
  • Applying eyedrops is a slow, tedious procedure.

The solution

In 2002, Bio-Logic Aqua Technologies Biomedical Research introduced Nature’s Tears EyeMist, the first effective, all-natural alternative to formulated eyedrops for dry, irritated eyes. For the first time, millions of contact lens wearers are obtaining instant relief from dry, irritated eyes…without eyedrops.

Nature’s Tears EyeMist solved the problem of getting moisture in extremely minute quantities past the lipid layer into the aqueous layer. This is accomplished very simply, by delivering the moisture as an ultra-pure, ultra-fine mist that emulates the air’s natural humidity. The mist is sprayed towards the face rather than into the eyes, enabling the tear film to extract exactly as much moisture as it needs, no more and no less. In most cases, all that is required to restore the tear film’s moisture content to full volume and comfort, is two to five nanoliters (billionths of a liter). That is far too little to apply with an eyedropper.

As an added benefit, delivering moisture in the form of a mist oxygenates the moisture, thus increasing the aqueous layer’s oxygen content.

A suggestion

The most beneficial component of eyedrops is the paraffin or oil that can serve as a sealer to slow tear film moisture loss. Eyedrops are most effective as a moisture sealer when the tear film’s moisture content is at full capacity. For best results, apply Nature’s Tears EyeMist immediately before applying eyedrops, and use the smallest amount of eyedrops possible. Since Nature’s Tears EyeMist has no dosage limit, it may also be applied between eyedrop applications, or when eyedrops are not convenient.

Ultraviolet Light, UV Radiation and Skin Care

The UVA and UVB components of sunlight may cause skin dehydration, sunburn, collagen damage and DNA damage

Sunshine is a wonderful thing. In plants, it stimulates green chlorophyll to produce free oxygen, enabling us to breathe. Sunshine invigorates, energizes and causes the skin to produce Vitamin D, the “Sunshine Vitamin.” Of course, sunshine can also give you a painful sunburn.

The primary “bad factor” in sunlight is ultraviolet (UV) light. UV is the component of sunlight that causes skin dehydration, sunburn, collagen damage, DNA damage and skin cancers such as melanoma. Education about UV light, combined with a few simple skin care precautions, can significantly affect skin (and eye) health.

Ultraviolet light is light with a wavelength just a little too short to fall within the visible spectrum (100 to 400 nanometers). Compare this to infrared light, which has a wavelength just a little too long to fall within in visible spectrum (700 to 3,000 nanometers).

Facts about UV light:

  • Earth’s ozone layer filters out 98% of UV rays. Of the UV radiation that gets through, 98% is Ultraviolet-A (UVA).
  • (UVA) has a wavelength of 400 to 315 nanometers (visible violet light has a wavelength of 400 to 500 nanometers).
  • UVA does not cause sunburn but can cause skin drying, collagen damage and rapid aging.
  • UVB has a wavelength of 315 to 280 nanometers.
  • UVB causes sunburn and DNA damage that can lead to skin cancers such as melanoma.
  • On the positive side, UVB stimulates the production of Vitamin D and melanin (melanin helps block UV rays).
  • UVC has a wavelength of 280 to 100 nanometers and is used to kill bacteria.
  • UVC can be extremely damaging to skin. You are most likely to encounter UVC at high elevations and in ozone depleted areas such as Antarctica.

Minimizing UV exposure:

  • Well hydrated skin, containing adequate water, is more resistant to the harmful effects of UVA and UVB than dehydrated skin (dry skin), with not enough water. Dry air, air pollution, forced-air heating and cooling and insulated walls and windows also contribute to dry skin.
  • Sunscreen, which blocks UV light, is recommended for facial skin anytime you go outside in sunlight, no matter what the season.
  • Sunscreen is most effective if the skin underneath is well hydrated. In addition to blocking UV rays, the lotion in sunscreen acts as a sealer to help the skin retain water.
  • The darker your skin, the higher the melanin component, the more resistant your skin is to UV rays.
  • As a sunburn heals, it temporarily stimulates melanin production (tanning).
  • Natural fabrics with a tight weave are effective in blocking UV rays. As with sunscreens, different fabrics and weaves have specific SPFs (solar protection factors).
  • A hat, sunglasses and long sleeves also offer important UV protection in sunlight.

To make sure your skin (and eyes) contain adequate moisture, drink at least eight glasses of pure water (in addition to coffee, tea, soda or juice) per day. Also, bathe often, keep your windows open when possible. Finally, for dry skin and dry eyes, get into a daily habit of frequent facial and eye misting with Nature’s Tears EyeMist or Nature’s Mist Face of the Water, hand-held water therapy devices from Bio-Logic Aqua Research.

Correct Application of Nature’s Tears® EyeMist®

Obtaining Maximum Benefit for Dry Eye Symptoms

Recent discoveries by Bio-Logic Aqua Research have resulted in Nature’s Tears EyeMist, the first all-natural, pH balanced water mist product to soothe dry eye symptoms. Correctly application of the eye mist is important for maximum benefit.

Benefits of eye misting.

  • Instantly soothes dry irritated eyes.
  • Convenient and easy to apply (even if your hand is unsteady).
  • No touching of eyelids, tilting back of the head or aiming the dropper.
  • Supplies only the amount of water needed by the eyes.
  • Does not flood tear film or interfere with the natural tear film structure.
  • Moisturizes contact lenses without removing lenses.
  • Soothes computer eye strain (also called “Computer Vision Syndrome” or CVS).
  • No additives, chemicals, preservatives or propellants.
  • Will not “run” eye make-up.

Correct application.

The most common application error is attempting to apply the eye mist as though it was an eye drop, by aiming it directly into the eyes. This can flood the eyes and lessen some of the benefits. The objective of eye misting is to create a swirl of moisture around the face, like humid air, from which the eyes absorb as much water as they need. Brief blinking is OK.

  • With eyes open, point the nozzle of the eye mist canister towards the side of your face, next to the eyes (if you point the nozzle directly at the eyes, there could be a reflex to pull away and close the eyes).
  • Press the top of the canister to release the eye mist.
  • Move the eye mist canister across face, 8 to 12 inches from eyes, in a one-to-two-second sweep. Do not mist directly into eyes.
