Dry eye is a syndrome in which the eye's ability to produce tears breaks down. Tears play an important role in moistening, protecting, and cleansing the eye. They are necessary for good corneal health. They also support contact lenses.

Dry Eye is a collection of symptoms that make up an eye condition that stems from an imbalance in the quantity or quality of tears bathing the eye. These symptoms include dry, red, gritty, and even watery eyes. Often, Dry Eye sufferers report the feeling of something foreign within the eye or eyestrain. Some people do not produce enough tears to keep the eye comfortable.

Tears bathe the eye, washing out dust and debris and keeping the eye moist. They also contain enzymes that neutralize the microorganisms that colonize the eye. Tears are essential for good eye health. In dry eye syndrome, the eye doesn't produce enough tears, or the tears have a chemical composition that causes them to evaporate too quickly.

Sometimes burning and itching eyes are due to environmental pollutants that might be eliminated by social action. If secondhand cigarette smoke is annoying, say so. If an industrial plant in the area is polluting, contact the EPA for solutions.

The retina is the nerve layer that lines the back of the eye, senses light and creates impulses that travel through the optic nerve to the brain. The macula is a small area in the retina that contains special light-sensitive cells and allows us to see fine details clearly. The optic nerve is the nerve that connects the eye to the brain and carries the impulses formed by the retina to the visual cortex of the brain.

Exposure to a broken metal halide bulb can burn the corneas. A small number of cases have been reported across the country and around the world, in Florida and South Dakota, Canada and Australia. Exactly how often it happens is unclear, but some experts suspect many cases go unreported or are mistaken for other conditions, such as pinkeye.

One of the most frequently used treatments for dry eyes is artificial tear drops. Did you realise that some drops contain a preservative that actually makes dry eyes worse? I have produced a comprehensive list of the most widely used drops and I have highlighted the good and the bad.

Chronic dry or burning eyes can be caused by age, some medications, and disease. Itchy, burning eyelids can also result from infection. Allergy is caused by an oversensitive immune system, which leads to a misdirected immune response. The immune system normally protects the body against harmful substances, such as bacteria and viruses. It reacts to substances (allergens) that are generally harmless and in most people do not cause a problem.

While over-the-counter lubricating eye drops are fine for self-treating mild cases of dry eye disease, people who are using these kinds of medications and not getting relief, or whose quality of life is being hampered, should seek the help of an ophthalmologist for further treatment.
