If I have "dry eyes" (and I DO), why then do my eyes "water"!


Question: If I have "dry eyes" (and I DO), why then do my eyes "water" so much !?
Answers:
Dry eye is not usually associated with a problem with the QUANTITY of your tears!. It more often a problem with the QUALITY!. There are three components to your tear film!.

The surface of the tears should be covered with an ample amount of oil The purpose of the oil is to lubricate and also retard evaporation of the watery component of the tears under the oil!. Oil is produced by the meibomian glands in the upper and lower lid margins!.

The second component is the watery component directly under the oil!. This serves to wet the eye and also remove debri and irritants from the eye (such as dust or dirt)!. It is produced by the lacrimal glands!.

The deepest component is the mucous layer!. This lays against the eye itself and serves as the base building block for all the components above!. It is produced by the goblet cells in the conjunctiva!.

The brain has no ability to control the amount of oils and mucous!. They are produced on a continual basis and cannot be stimulated by the brain to produce more!. The brain does, though, have the ability to produce huge amounts of watery component!. It responds like it does because it thinks you have something in your eye that is an irritant because it is not lubricating well!. Like when you get something in your eye and your eye waters profusely!.

So, if your brain senses that your tear quality is suffering and you are not lubricating your eye well it cannot increase mucous production nor oil production!. So it does the only thing it can by pumping large amounts of watery tears into the eye to try and fill the gap left by an underproduction of mucous or oils!. What most people notice is periods of excessive tearing followed by peroids of normalcy!. That is because as soon as the extra watery tears help out the brain no longer gets information from the eye saying there is something in the eye!. It therefore quits producing extra tears!. But before too long the lubrication problem returns, the brain senses irritation, and it starts the whole cycle over again!.Www@Answer-Health@Com

The body has alot of responses for self defense!. When your eyes are dry, they feel gritty, sandy, and irratated!. So the brain sends a signal to the tear glands to "wash" away the gritty, sandy feeling, hence the 'watering' that takes place!. The negative to this process is the tear that is triggered is just like the tears that you cry, and it washes away the good tear that coats your eye everytime you blink!. Which causes the eye to feel worse!. That is why the doctor recommends using artifical tears!.Www@Answer-Health@Com

Because the "tears" are trying to keep them damp!.Www@Answer-Health@Com
