What Are The Most Common Causes Of Dry Eyes?

Meta Description: Do not worry if you have dry eyes and are not aware of what may have caused it. It is a problem for many. Here are some major causes of dry eyes syndrome.

It happens that the eyes of even a perfectly healthy person become dry. And if this condition continues for long enough, then damage to the cornea is possible – and this is a direct path to eye diseases. We investigated the reasons why dry eye syndrome can develop in a person who does not suffer from autoimmune pathologies or serious eye diseases.

What Is Dry Eye Syndrome?

Dry eye syndrome can develop either with a lack of tear fluid or with too rapid evaporation. According to scientists, today, 5-6% of the entire population of the planet suffers from dry eye syndrome. Classic symptoms of dry eye syndrome are:

  • Burning sensation
  • A feeling of dryness
  • Feeling like something is stuck in the eye
  • Pressure behind the eyes
  • Reddening of eyes

Most often, both eyes suffer at once, which indicates a systemic problem. The eyes with dry eye syndrome may even water because of irritation, but these are not the tears that are needed. These tears do not protect the eye from external influences and have no lubricating properties. Let’s find out the major causes of dry eye syndrome:

  1. Age

Over the years, the risks of developing dry eye syndrome increase. Moreover, a third of older people (34%) suffer from this disease. This happens because as we grow old, the body’s ability to produce tears fades away, causing dry eye syndrome. The solution to this problem is to use a special eye fluid called an artificial tear. It will help to moisten your eyes and save you from irritation.

  1. Alcohol Consumption

Consuming alcoholic beverages more than the normal amount can harm many organs of your body, including the eyes. This happens because alcohol is a diuretic, which means it enhances the flow of urine in the body and causes dehydration. It is a risky situation for those already suffering from dry eye syndrome.

Thus, doctors recommend getting treatment for alcoholism to get rid of alcohol-related health problems. However, many people living in states like North Carolina, where people consume alcohol at a rate greater than the national average, do not consider getting help from rehab.

This is the reason for widespread alcohol-induced health problems, including dry-eye syndrome in North Carolina. So if you are a resident of that State, you must know that some of the best rehab centers in NC are state-funded. And it would help if you get the treatment before things get out of hand.

  1. Medicines

Many medications have side effects that include decreased tear production. This list includes:

  • Beta-blockers (for the treatment of hypertension) because they decrease the activity of the lacrimal glands and reduce the stability of the tear film.
  • Antihistamines (for the treatment of allergies) because they reduce the water content in the tear fluid by a third
  • Diuretics reduce the volume of intracellular fluid and the volume of circulating blood, which causes dryness of all mucous membranes, and not just the eyes.
  • Antidepressants, because they affect the hormonal balance and, as a result, the production and composition of the tear fluid drops
  • Hormonal contraceptives also reduce the concentration of lipids in tears and affect the work of the meibomian glands.

And in such a scenario, even artificial tears provoke dryness in the eyes, as they contain preservatives that negatively affect the organs of vision.

  1. Working On Computer

Contrary to popular belief, it is not the monitor or the small print that causes dry eyes when working at a computer for a long time. Modern monitors and gadget screens have moved far from the cathode ray tubes, which were used at the dawn of universal computerization. 

Today they are practically harmless to the eyes. However, they may be the reason for dry eyes syndrome because a person blinks much less when working at the monitor. You can avoid this situation by blinking more, so next time you work on a laptop, don’t forget to blink.

  1. Menopause

As mentioned above, hormonal imbalances can also cause dry eyes. All women in the world, having reached a certain age, enter the period of menopause when the hormonal balance changes and the level of estrogen in the blood decreases. 

The decrease of this hormone causes dry eye syndrome as estrogens are responsible for moisturizing the mucous membranes. As a result, the production of tears gets reduced. If you are experiencing a similar situation, consult your doctor.

  1. Eye Surgery

Possible side effects after laser vision correction include dry eyes due to temporary damage to the nerves that innervate the cornea. This leads to a decrease in the production of tear fluid. This condition can last for several months after the operation or even a year. But don’t be alarmed; this is normal. You should discuss with your doctor which eye drop will be most effective and safe during temporary dry eyes after surgery.

  1. Lack Of Vitamins

The list of vitamins, a deficiency of which increases the risk of developing dry eye syndrome, is vitamins A and D. With a lack of vitamin A, the stability of the tear film decreases. However, studies have shown that even short-term vitamin A supplementation improves fluid tear quality and reduces dry eye symptoms.

Lack of vitamin D is also associated with increased tear salinity and impaired tear film stability. Observations show that taking a vitamin D supplement increases tear fluid production, reduces tear film instability, relieves corneal inflammation, and even enhances the effect of drugs for treating dry eyes.

  1. Dehydration

Sometimes dry eyes are the result of general dehydration. Other symptoms of this dangerous condition include a dark color of urine and, in general, a decrease in urine volume to a minimum, dizziness, extreme fatigue, and lack of energy.

Dehydration is a harmful condition for the body. You should not bring yourself to it, even when it comes to competitive goals. So always keep a water bottle with you and do not forget to drink after every hour. Such a habit will prevent you from developing dry eye syndrome.

Take Away

If you have dry eye syndrome, it may be because of the above-mentioned reasons, and you must go to the doctor immediately to cure your eyes. This is because untreated dry eyes can lead to several complications, so you must visit your doctor to get relief.
