Watch Out for Eye Dehydration During Summer Heat Wave

19 Jul

During a summer heat wave, warns Natures Tears® EyeMist® inventor and Bio-Logic Aqua Research Founder Sharon Kleyne, the eyes are especially vulnerable to dehydration or loss of surface water. The ability to recognize, prevent and treat dehydration of the eyes, sometimes called  “summer dry eye,” could prevent much discomfort and possibly save one’s eyesight. .

The surface of the eye at the cornea is 98% water. When the amount of ocular surface water, which is mostly contained in the “basal tear film,” begins to drop, either from evaporation or poor tear production, the results are dehydration and dry eye complaints. When eyes are exposed to high temperatures, low humidity, and intense sunlight, the tear film water protecting the eyes and enabling sight evaporates faster than at other times.

Tear film dehydration and dry eye can cause eye discomfort, water eyes, dry eyes, itching eyes, burning eyes, fatigue, headaches, blurred vision and many other symptoms. Too little tear film water, among other things, stimulates the production of inflammatory hormones in the tear film, causing inflammation and discomfort.

Summer is also allergy season, with dramatic increases in airborne pollen. When the eyes’ natural defenses against allergies and pollen are diminished due to insufficient tear film water and the presence of inflammatory hormones, the allergic reaction to pollen will be greater.

Dry eye and dehydration caused by a summer heat wave and intense sunlight can be minimized or avoided by drinking eight glasses of water per day in addition to other fluids, wearing sunglasses, taking frequent cool showers and baths, avoiding direct sunlight, keeping your home humidified, and replacing water and salt when you become overheated.

A quick and easy method of supplementing lost tear film water and alleviating dry eye complaints during a summer heat wave is to carry Natures Tears® EyeMist® from Bio-Logic Aqua Research with you and apply it frequently. Natures Tears® EyeMist® is a personal hand-held humidifying device that instantly relieves dry eye and allergy eye complaints. The product contains 100% all-natural pH balanced tissue culture grade water – ideal for application to the eyes.

Because Natures Tears® EyeMist® is 100% safe, the product maybe applied whenever dry eye or allergy eye discomfort are experienced. Natures Tears® EyeMist® is compatible with all other eye applications

Natures Tears® EyeMist®. The best – and only – all-natural water mist for relief of dry eye and allergy eye caused by a summer sun and heat waves.

Understanding Tear Film and Eye Hydration Could Prevent Dry Eye

Bio Logic Aqua Research is a premier water technology company, specializing in products that support moisture in the skin and eyes.

According to Sharon Kleyne, Founder of Bio-Logic Aqua Research, understanding eye hydration and the eyes’ all-important tear film and could help prevent dry eye disease.

Especially important is the environment’s role as a cause of dry eye.

Eye dehydration and tear film water loss can weaken resistance to bacterial and viral invasion, impair visual functioning and lead to numerous eye diseases and conditions.

Dehydration related eye conditions include itching and/or burning eyes, blurred vision, transient dry eye syndrome, severe dry eye syndrome, corneal ulceration, glaucoma, computer eye strain, eye allergies, eye cancers and more.

According to Sharon Kleyne, the incidence of eye dehydration and dry eye has dramatically increased in the past 20 years and is becoming a global health crisis. Much of the increase can be attributed to environmental factors.

Environmental factors that could dehydrate the eyes and tear film could include:

Indoor conditions such as forced-air heating and cooling and insulated walls and windows.

Lifestyle choices and personal habits that could contribute to eye dehydration include wearing contact lenses, prolonged computer use, participation in extreme sports (with lots of perspiration and exposure to heat and sun), caffeine and alcohol consumption, not drinking enough water, too much time spent indoors, cigarette smoking, medications, etc.

Exposure to smoke, dust, wind, extreme heat and cold and other outdoor conditions could also contribute to eye dehydration.

A major contributor to eye dehydration is global climate change because the tear film obtains much of its water from the surrounding humidity in the air. In many areas, the air in becoming dryer and the humidity lower. This lowers the potential for hydration from the air and increases tear film water evaporation.

Even where the air is not dry, the humidity could be contaminated by air pollution, creating dehydrating and unhealthy conditions.

Eyelid Inflammation and Eye Dehydration

The following is courtesy of The Sharon Kleyne Hour radio show. Mrs. Kleyne is a pioneer in the field of water hydrotherapy and health. She hosts a bi-weekly radio show dedicated to educating the public about health and the environment.

Marguerite McDonald is an Ophthalmologist and LASIK pioneer.

She said that 20 to 30 million people in the United States show symptoms of early stage dry eye disease. Also, six million US women and three million men suffer from advance dry eye.

Dry eye increases with age and is more prevalent among women. It is also a side effect of numerous medications. Modern, climate controlled, energy efficient buildings can also cause dry eye.

Computers are a huge contributor to dry eye. When working at a computer, the blink rate drops from two-times a minute to three-times a minute. Other factors that can dehydrate the ocular tear film include arthritis, gout, eye surgery, poor nutrition, not drinking enough water, low thyroid, not enough sleep, contact lenses and topical eye medications. Eyelid blink disturbance cause by strokes and other diseases can also result in dry eye.

A disease called “blepharitis” which is inflammation of the eyelids, can also cause dry eye symptoms. The eyelid are also home to the tiny meibomian glands, which secrete oil (lipid) onto the tear film. This oil, among other things, prevents the water in the tear film from evaporating. Should the eyelid inflammation affect the proper functioning of the meibomian glands, as it often does, the evaporation rate can increase dramatically.

Symptoms of dry eye: Need to go to bed earlier, difficulty reading, anxiety/depression, increased eye allergies (since the eye can’t wash away allergens as easily), sensation of dryness, redness, fluctuating vision, tired eyes, etc. If the problem is worse at the end of the day, it’s dry eye, if it’s worse in the morning, it’s more likely blepharitis. Burning is a symptom of blepharitis.

There is a drug called Restasis that helps the eye’s lachrymal glands produce more and better tears. This is extremely helpful in treating dry eye symptoms. Also, Nature’s Tears EyeMist helps to restore lost tear film moisture without washing away the lipid layer. With no treatment, dry eye will usually get worse over time.

Dr. McDonald recommends annual MD eye doctor visits beginning at age 40. She also recommends newborn infant vision checkups and periodic well-baby vision checks. The American Academy of Ophthalmologists has excellent programs for children at http://www.GetEyeSmart.org.

Does dry eye correlate to low humidity? Not conclusively but the rate does tend to be higher in cold climates, possibly because people there spend more time indoors.
