Tears are a very important component of good vision. In fact, even when we are happy, our eyes are full of them, given that their role is to provide moisture and lubrication to help us see better, and keep our eyes healthy.

But what is a tear? And why do we sometimes weep too much or too little? And how to resolve the condition of dry eye?

What are tears

Tears are a particular component made by our body as a mix of water, lubricants, mucus, antibodies and special proteins that keep any infections at bay.

Their production is delegated by special glands that are located around the eye and ... for this reason it is easy to say from this moment that dry eyes often indicate a tear system that is not functioning properly.

When tears do not provide enough moisture to the eye, you may therefore notice a condition of "dry eyes", irritated eyes, a feeling of "something in the eye", itching, redness, blurred vision, sensitivity to light.

Tearing of the eyes

Sometimes one is led to think that dry eyes are "tearless" eyes. In fact, the opposite is often true: dry eyes are eyes with too many tears! Because?

It is quite simple: the lack of moisture irritates the eye, sending a warning signal through the nervous system, inviting greater lubrication.

At that point, the body, through the glands that are responsible for this purpose, creates many more tears to try to compensate for the dryness. However, these "additional" tears are not normal tears, but are mostly made up of water. Therefore, they can "wash" away any debris that may be present on the eye, but are unable to effectively cover the surface of the same.

What causes dry eyes

Sometimes, the dry eye it is favored by a lack of balance in the lacrimal system. Or from the air conditioner, from a too high heating or from other elements around the eye, which could dry the tear film.

Think also of:

  • a natural aging process, especially with menopause,
  • side effects of some medications such as antihistamines,
  • diseases that affect the ability to produce tears, such as Sjogren's syndrome, rheumatoid arthritis and vascular diseases of collagen,
  • problems that do not allow the eyelids to close as they should.

Of course, the list of causes of dry eye it could be much more extensive. We encourage you to speak to your referring physician to find out more.

How dry eye is treated

There are several options of treatment of dry eye and, obviously, you will have to ask your ophthalmologist what to do in order not to run into gross errors.

In principle, a first treatment could include the use of artificial tear drops. This is the most common treatment, not least because many types of particularly effective drops are available over the counter without a prescription.

However, keep in mind that no product necessarily works for everyone, so you may have to try a few to figure out which one is right for you. If you have chronic dry eye, you should also use the drops even when your eyes “feel” good, otherwise they won't stay lubricated enough. If your eyes get dry during sleep, you could also opt for a thick product, such as an ointment, at night. You could also try to sleep with airtight goggles, which will create a mini chamber of humidity for your eyes.

It is also possible that the ophthalmologist may evaluate one temporary punctual occlusion. Your doctor may choose to close the punctum, that is, the duct that drains tears from the eye. It could start with a temporary cap designed to dissolve over time and, based on how it works, figure out whether or not permanent caps can help. Generally speaking, if the temporary caps work well, your doctor may switch to more durable or long-lasting ones.

Among other treatments, we note how often the application of a testosterone cream can be positively evaluated: dry eye can in fact be related to a lack of testosterone in the oil glands on the eyelids. Your doctor may then give you a testosterone cream that you apply to your eyelids, helping the lubricant to work better.

Of course, most of the causes of dry eyes can be easily tackled ... by removing the risk factors!

For example, in many cases, dry eyes are caused by a climate that is too hot and not very humid. In these cases, it is sufficient to install a humidifier in the room or turn off the heating (or at least lower the temperature) to find good relief.

More information

In short, as you have seen in these few lines, the causes of dry eyes can be very numerous and, after all, it is difficult to try to summarize them in a few lines.

What is relevant, however, is that most of the determinants of dry eye are common and transient. It is therefore sufficient to remove the trigger to be able to restore good ocular well-being.

In other cases, these are situations favored by aging. In these cases, the evolution of dry eyes is gradual, and often the application of simple eye drops can be of great help.

We advise all those who are affected by this prejudice to speak immediately with their ophthalmologist and try to understand which treatments to adopt in order to better cope with this situation, obtaining better visual comfort.
