We all know that our whole body works on energy, and this energy is circulated in the body by electrical and magnetic waves. For our sense organs to function this energy is continuously used up, more so with the eyes. As soon as we wake up, we use our eyes before we use any other sense organs. Even during sleep our eyes are continuously moving, so much so that by the end of the day what we get is tired eyes.
Because the uses over 80% of our total energy output and if there is some deficiency in them the energy used is more leading to the tiredness of eyes. Eyes get nourishment from the tears in fact 70% of the nutrition to the eyes is through the tears. Hence it is necessary for the eyes to have enough water or lubrication for proper nutrition, thereby preventing tiredness of the eyes, and if you are wondering how this is related to dry eyes and how can we cure it this article may come in handy.
Tears form on top of the cornea and conjunctiva of the eye. Integrity of the tear film is important and is maintained because of the composition of the tear film itself. Essentially, it consists of three layers-lipid, watery and mucus layers. The muscular layer lies adjacent to the microvilli of the epithelial cell of the cornea. As this cell is hydrophobic and cannot absorb water by itself, the mucus layer swells with water and transfers the water molecules through the cell membrane of the microvilli. Thus deficiency of the tear film leads to the dries of the cornea cells and eyes.

- Dry eyes can also be the result of inflammation in the lachrymal glands. A vicious cycle follows in that the eye irritated by dry eyes, can over stimulate the nerve fibers of the lachrymal glands which causes further lachrymal gland inflammation due to its over stimulation and thus reducing the tear formation.

- Wear glasses while going out in the sun or while riding and goggles during swimming.
- Keep the home environs humid, between 30 and 50 percent. During winter a humidifier may be used to add moisture to dry indoor air. Additional humidity can be created by wearing special glasses that form a moisture chamber around the eye.
