For optimal vision and comfort of your eyes they need to be properly lubricated. A film of tears coats the eyes every time we blink keeping them moist and comfortable, but when there is a dysfunction in this process dry eye syndrome will occur. It can happen in one of the three layers of the film of tears that include the mucus layer, the aqueous layer and the lipid layer.
A layer in the innermost area of the eye is called the mucus layer. The cells that line the eyelid produce this very thin mucus. Its job is to evenly distribute the next layer which is saline-like and keeps the eyes hydrated.
The next layer, the saltwater solution, is known as the aqueous layer and it is produced in the glands of the upper lids and the tear glands. Its job is to keep the eyes moistened and clean by flushing out any debris like dust or foreign matter. This is the layer where problems most commonly occur.
When the tear film is dysfunctional dry eye syndrome will occur, in American it affects nearly 25 to 30 million. Anyone can get it but it is more common in women and people who are 40 or older. There will be a decrease in the production of tears. The mucus or lipid layers can have abnormal production and this will create less tears or more evaporation.
Dry eye is a common problem of the the film of tears over the eyes and affects about 25 to 30 million people in the United States. It can affect anyone but primarily affects women and those over the age of 40. Symptoms will include a decreased tear production. This can manifest from abnormal production of the lipids or mucus layers. This can result in lessened tear production or excessive evaporation.
Some diseases are responsible for dry eye syndrome such as Sjogren syndrome, lupus, rheumatoid arthritis, hormonal issues, autoimmune diseases and age. When there is insufficient production in the lipid layer over-evaporation will occur. Also some medications can cause decreased tear production such as antihistamines, oral-contraceptives, beta-blockers and antidepressants.
A humidifier can add moisture to the air and the reduction of the use of fans is advised. Hot compresses and massages can stimulate production in the lipid layer and an air filter can keep dust from getting in your eyes. There is no cure for dry eye syndrome but there are treatments.
