Our tears consist of three layers, each of which has a different and essential role for the function of the tears and hence – for the function of the eye. The innermost layer is the mucous layer, followed by the aqueous layer and the outermost is the fatty layer. Each layer is produced in a different area of ​​the eye by different glands or cells. The mucous layer is essential for the uniform distribution of tears over the surface of the eye, the aqueous layer provides moisture and protection while the fatty layer inhibits the evaporation of tears into the outer space. A defect or reduction in the production of any of the layers The above will lead to dry eyes.

The causes of dry eyes are varied, some of them depend on our lifestyle and can be changed, for example smoking, spending a lot of time in places with low humidity such as closed air-conditioned spaces, frequent use of screens, an unbalanced diet leading to a lack of essential fats and with them a lack of fat-soluble vitmans. Other conditions outside our control may be eyelid diseases, past eye surgeries, diseases such as Sjörgen’s syndrome, Parkinson’s, use of drugs such as psychiatric drugs, anti-allergy drugs, anti-hypertensive drugs and more.
