Dry eyes

What are dry eyes?

our tears are made up of a mixture of water, mucus, oils, proteins and salts – which all help to maintain good eye health.

Dry eyes is a common condition that happens when your tear production is impaired. Your tears work as a lubricant for your eyes and help to wash away debris. Tears also protect your eyes from bacteria, moisten them, and maintain a smooth surface.

The lack of lubrication from your tears can lead to your eyes drying up. This causes them to become red and sore. Other symptoms can include your eyes feeling painful and gritty, blurred vision and your eyelids sticking together (especially in the morning).

Dry eyes can often be treated easily with over the counter medications.

Who gets dry eyes?

Anyone can suffer from dry eye syndrome, and it’s usually caused by external factors like windy or smoky environments. Certain lifestyle habits, such as drinking and smoking, can also increase your risk of developing dry eyes. It’s typically more common in people above the age of 50, and women facing hormonal changes during periods, pregnancy or menopause.^[1]

How common are dry eyes?

It’s quite a common issue. If it’s caused by environmental conditions such as the weather then it’s quite easy to avoid. It rarely ever causes enough of a problem to require medical attention, and it can usually be treated with over the counter medications.

If your symptoms are being caused by other conditions, such as hormonal changes, then you might be given other treatments alongside your dry eye medication to help tackle the root cause of your symptoms.

Can dry eyes lead to other problems?

Dry eyes can lead to other conditions that might require further medical attention, such as conjunctivitis, abrasions of the corneal surface, corneal ulcers and vision loss.
