Dry eyes is majorly due to a lack of adequate tear production. Tears are very complex in nature being a sophisticated mixture of fatty oils, mucus and water. The mixture is very important in lubricating the surface of the eyes and making them clear and it is also vital in the protection of the eyes from infection. For some people, however, the causes are not just decreased tear production it might be imbalances in the constituents of the tears. Below are the various courses of dry eyes.
The first of the most common is inadequate tear production. This is because basically when individuals are unable to produce enough tears that offer lubrication and protection to the eyes. This majorly happens because of aging as people above the age of 50 are highly likely to experience these because they would not have adequate tear production. Certain medical conditions like rheumatoid arthritis, lupus, diabetes, thyroid disorders, scleroderma, and vitamin A deficiencies are also highly likely to cause dry ice. It also highly likely to experience dry eyes due to laser eye surgeries and also TR blend damages from radiation and inflammation.
Another major cause of dry eyes is an abnormal level of tear of operation. This mostly happens in an environment that not have enough moisture. This may, therefore, be exposed to smoke, dry air or wind. High altitudes are also highly likely to cause this problem especially with people who are in airplanes. Tear operation might also be caused by a lot of eyelid problems and also for people who have long stretches of time in using the computer or their phone, therefore, resulting in blinking less often.
The imbalances of your tear composition is also another major cause. The major constituents of the tears include water, mucus, and oil. If any of these constituents are produced in inadequate amounts, then an individual experience dry eyes. There are people who might have cases of the oil field produced by the meibomian glands becoming clogged. These are basically the small plants that are at the age of the eyelids which are responsible for the production of oil for tears. Blocked meibomian glands are very common for people who have experienced inflammation around the age of the eyelids which is also commonly known as blepharitis. People also have experienced various skin disorders and rosacea are in the high likelihood of missing some of the constituents of your composition. There are also other significant issues that might originate from an imbalanced diet leading to the tear composition becoming quite imbalanced particularly with the lack of vitamin A and omega-3 fatty acids.
