Dry eye is caused by a problem with your tears. When you blink you leave a thin layer, called the tear film, over the front of your eye. This tear film keeps the front of your eye healthy and helps the eye focus properly, giving you clear vision.
The tear film is made up of three layers which includes the mucin layer, watery layer and lipid layer. If you don't produce enough tears, if your tears aren't of the right quality or your tears aren't spread across the front of your eye properly then you may develop dry eye.
Often dry eye is a natural symptom of getting older but can also be affected by other things such as medications, pre-existing health conditions, use of contact lenses and eye surgery.
In the below video, Alison talks about her diagnosis of dry eye and how she manages it.
If your eyes feel dry, uncomfortable and irritated or you feel like there’s something in your eye all the time, then you should tell your GP, optometrist (optician) or ophthalmologist (hospital eye doctor).
After taking a detailed history and examining the front of your eyes, your optometrist or ophthalmologist may want to carry out further tests to help them decide how to treat your eyes.
The types of test that an optometrist might undertake are covered in detail in our Understanding Dry Eye guide (see download links at the beginning of this page).
You can’t "cure" dry eye, but there are some treatments that can help your eyes feel more comfortable.
Once your ophthalmologist, optometrist or GP has confirmed you have dry eye, they will discuss what can be done to help you.
There are three main ways to treat dry eye:
Making the most of your natural tears
Using eye drops
Reducing the drawing away of tears
All three of these treatments are looked at in detail in our Understanding Dry Eye download guide.
