The specialized gland dependent on the eye's structure performs the role of continuous tear production to protect the surface of the eyeball while maintaining vision. The eye has a frequent self-blinking mechanism and the periocular membrane will quickly be completely covered by the eyeball, and tears are secreted and spread out to lubricate the eyeball. Thanks to tears, foreign bodies or pathogenic microorganisms can hardly enter the eye and cause significant damage to the eye.
The lacrimal gland is underactive or the tears on the surface may evaporate too quickly, possibly due to:
Insufficient tear secretion. Over time, aging also makes the tear glands of the eye less functional. In addition, other causes such as drug use, other diseases... also cause the lacrimal gland to function improperly. When tears are not produced, the surface of the eyeball is not replenished with tears to be protected. Along with climatic conditions such as dry weather, strong winds.... can make tears evaporate faster. Due to an abnormality in the quality of tears or the protective film of the eye affecting the lacrimal gland - the cause of dry eye disease. The tear film with optimal eye protection function is composed of 3 layers which are fat layer, water layer, mucus layer... Substandard tear quality can cause tears to evaporate easily or because the structure of these three layers is not up to the standard, making tears not spread evenly in the eyes
