Your tears are suppose to drain behind your nose but because your tear ducts and the area across your eyelids are clogged the eyes ask the brain to provide tears because your ducts and moisture area on underneath the eyelids cannot. So your brain is constantly flooding the eye with water or tears to help the eye stay moist. If not then your eye would develop some serious problem, like bacteria which is normally washed away by your tears.
So to correct this your eye doctor will tell you to put eye drops made for tears in your eye four times a day. Also you must use a warm compress and gently wipe away the dust that has clogged your moisture area which is the under layer beneath your upper and lower eyelashes.
Use the compress at least two times per day. Also try and stay out of windy conditions and the cold while you are going through this. Also where shades outside to protect your eyes from the sun and the wind.
Very important, make sure you drink your daily fill of water which is 6 eight ounce glasses of water. Water is the great purify and moisturizer our body needs.
This works, I know because both my eyes was pouring water all day long. After going to the optometrist and starting this process I now notice that my right eye has completely stop watering like before and my left eye is tearing less and less. It is going to be tedious and slow at first but stay with it and you will notice the difference. Oh yea, see a Optometrist or eye glass doctor because the specialist called Ophthalmologist will not see you for Dry Eye conditions.
