Dry, itchy eyes are common, and there are several possible causes for them. These include tear gland dysfunction, environmental conditions, and daily habits. While the end result is typically called "dry eye" in all cases, the cause sometimes affects how it is treated.
This is the most modern cause of dry eye. When you look at a computer screen, your blinking rate tends to slow down. This stops your lubricating tear layer from being refreshed often enough, and the eyes get dry. Often, this effect is combined with other characteristic symptoms to form a condition called "computer vision syndrome."
Dry environments speed the evaporation of tears, and when dust is included in the mix, further dryness and irritation result.
Normal, non-crying tears are made of three layers: A lipid layer, a watery layer, and a mucin layer. Each one of these is produced by a specific set of glands in the eyes and eyelids. If any component isn't being produced in enough quantity, the symptoms of dry eye can appear.
The most basic dry eye treatment is to use eye drops made for combating the symptoms of dry eye. These drops have a lubricating factor that plain drops do not.
Because truly eliminating the problem of dry eye requires addressing its root causes, your Williamsburg eye doctor will examine your eyes to make sure that they are properly producing tears. Then, when possible, any problems here will be addressed. This will make it so that your natural tears are healthier.
If nothing is found to be wrong with your tear production, you'll be asked about your lifestyle. Steps to protect your eyes from your activities, such as wearing glasses that block the blue light from computer monitors, will be recommended.
To be examined for dry eye and get a treatment that addresses the cause of the problem, just make an appointment with our optometrist here at Eye Center of Virginia in Williamsburg.
