Dry eye is a common condition that can affect comfort and everyday functioning. Here you will find an explanation of the causes of dry eye, its symptoms and the ways it is treated.
You're Not Pretty When You Cry
Apart from regular contact lens users, few people pay much attention to eye moisture. Yet the eye's ability to lubricate itself and produce tears is very important for both eyes to function properly. Tears do more than moisten the eyes. They are equally responsible for keeping them in good condition, preventing infections and keeping unwanted substances out. Tears clean various microorganisms from the eye's surface and ensure that the corneal surface is not damaged.
Another important thing to know about dry eye and tears is that tears have three layers. The inner layer contains proteins, the middle layer is produced by the lacrimal gland, and the outer layer is an oily layer produced by the sebaceous glands.
The main cause of dry eye is poor functioning of the oily layer of the tears, causing the eye to produce tears that evaporate very quickly. Unlike a properly functioning eye, a dry eye dries out rapidly and causes uncomfortable sensations.
Symptoms
Dry eye symptoms include itching, a sensation of "grains of sand" in the eye, burning, heaviness and fatigue. All these result from improper functioning of the oily tears.
How Is It Treated?
Treating dry eye requires much more than ordinary eye drops. Anyone who regularly experiences the problem knows that ongoing use of eye drops does not necessarily make it disappear. The first step is to see an ophthalmologist for an accurate diagnosis and learn how to manage the condition. Only when you are sure of the problem can you reach the solution needed to receive the appropriate treatment.
In the most extreme cases, the doctor will recommend surgery to restore normal lacrimal gland function. However, the problem can be prevented through early diagnosis and assistance from expert professionals who can prescribe the precise medications for your condition.
