4 Causes of Dry Eyes

Posted on: 26 February 2018

Having dry eyes can be a very unpleasant experience. You may find that your eyes feel itchy or watery and your vision may become blurred or your eyes may feel more sensitive when exposed to bright light. There are a number of possible causes of dry eyes. Read on to find out more.

Allergic Reactions

If you are allergic to dust or pollen, you may find that this can cause your eyes to become dry. If an allergic reaction is responsible for your dry eyes, you may notice that you only develop the condition during certain times of the year or in certain places. For example, if you often develop dry eyes when outdoors in the spring and summer, it is likely that this is caused by an allergic reaction to pollen in the air. In the short term, wearing sunglasses and rinsing your eyes when you return home can help to reduce the impact of allergens on your eyes. An optometrist may be able to prescribe eye drops which will also help to address this problem.

Side Effects of Medications

There are a wide number of medications which can affect your eye's ability to lubricate itself. The medications which most often cause dry eye problems are antidepressants, beta blockers and painkillers. If you notice that your eyes become dry when you start taking a new medication, you should speak with your doctor and explain the situation. Your doctor may be able to prescribe you a different type of medication which causes fewer side effects.

Vitamin A Deficiency

If your body is not receiving enough vitamin A, this can cause your eyes to become dry. Vitamin A, which plays a key role in eye health, can be found in many types of food such as carrots, pumpkins and sweet potatoes. Broccoli, spinach and kale are also great sources of vitamin A. 

Environmental Factors

If you are spending a lot of time in an environment which has very dry air, this can cause moisture which is sitting on the surface of your eye to evaporate. As the moisture evaporates, it can cause the eyes to dry out. If you live in Northern or Central Australia, the high temperature and desert-like conditions can lead to problems with dry eyes. However, even if you live and work in a city, air-conditioned rooms can also become very dry, and this may affect your eyes. The best way to deal with dry eyes caused by your environment is to administer eye drops.
