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.
