There are two types of dry eyes conditions: it can be either temporary, or it can be chronic. A temporary dry eye can be due to a number of simple and temporary factors such as excessive reading or exposure to a screen, extreme weather conditions, or lack of sleep, among others.

What causes dry eyes?

There are several causes of dry eyes, and some of them may be something you always do, or something that you cannot avoid entirely

Here are some of the things that can cause dry eyes.


As you get older, you get more prone to dry eyes. Studies have shown that once people reach the age of 50, tear production decreases and the chance of getting dry eyes increases.

The meds you take

There are certain medications, or a combination of some, that can temporarily affect your eye’s ability to create moisture through tears. If this is the cause, you can ask your doctor for an alternative that would not cause dry eyes, or you can simply ask for artificial tears in the form of eye drops. You can easily buy the best eye drops online as well.


You may have read too much throughout the day or have stayed in front of the computer for an extended period of time. This can cause dry eyes. This is because when we read or look at a monitor, we tend to blink less than we normally would. In turn, this would result in our eyes getting less lubrication than it should and thus, we end up having dry eyes.

Vitamin A deficiency

Most of us know that vitamin A is good for the eyes. Normally, you would get enough vitamin A you need from a healthy and balanced diet. However, if you have certain conditions that make you have deficiency for this, you may end up having dry eyes, among other eye problems that you may experience.


If you are dehydrated, a lot of your bodily functions may start to not work properly. You might start feeling dizzy, light-headed, weak, and have dry eyes, among other symptoms.

Wearing of contact lenses

When you use contact lenses, you are putting your eyes in an incredibly stressful situation and getting extremely dry is one of the results of it. This is why you should always maintain moisture on your eyes while wearing your lenses by using artificial tears. The best contact solutions can do this for you.

If possible, you should also avoid wearing lenses for a prolonged period of time.

Sjogren’s syndrome

One of the possible causes of a chronic dry eye condition is Sjogren’s syndrome. This is an autoimmune condition that causes your white blood cells to attack your salivary and tear glands, causing you dry mouth and dry eyes.

How can you treat dry eyes?

Artificial tears/eye drops

Most of the time, an over-the-counter eye drop, or artificial tears formula can do the job for your dry eyes. You may need your doctor’s recommendation in some cases, but you can always get one without any prescription. Among other brands, GenTeal is one of the most popular and recommended brands for eye drops.


If the cause of your eye drops is due to over exhaustion of the eyes, the solution can be as simple as taking a rest. Blink often, and if possible, look at a wide scenery to ease the strain and stress on your vision.

Possible medications or treatment

In cases of chronic dry eyes or dry eyes caused by autoimmune conditions, your doctor may recommend treatment or in some cases, even surgery. It is always better to consult your doctor if you feel like your dry eye situations are not normal anymore, so you can be guided on proper steps depending on the specifics of your condition.
