Explain how tears occur
When we talk about tears, we identify the eyes where the eyes contain the so-called glands of tears and these glands are present when the eyelashes meet the upper eyelid of the eye above the outer part of the eyelid. The lacrimal glands when excreted tears must be a bank to move the liquid is the so-called channel Tearful. Usually, the glands secrete tears in response to an effect. The tears also act as moisturizing the eye and cleaning it from dust spray that is attached to the retina. There are small tear glands that secrete a mucus that protects the eye by encapsulating it to protect it from dehydration. When the eye bleeds, the glands produce a huge amount of tears Do not stick to the surface of the eye because the mucous material is unable to discharge tears, so tear ducts shed tears outside the eye.
Causes of eye dilution
- This is what we sometimes call dry eyes, and the problem of eye dryness is one of the most important problems of eye dimming. Therefore, it is recommended to use moisturizers of the eye .
- Other causes of eye dehydration include: The eye contains tear ducts in which the water fluid occurs. When the ducts are blocked due to a viral infection, the eye begins to excrete more tears. There is no channel to drain the eye. This usually occurs when you also cry and is sorting out large amounts of tears because of crying and grief.
- We also refer to the hole where the eye is connected to the nose called the lacrimal sac and has a close relationship with the tear duct and is also connected to the trunk of the nose, so the tear occurs when the lacrimal duct is inflamed due to cold and cold, the eye begins to excrete the tears and mucus itself.
