What are dry eyes?

Like its name suggests, dry eyes (sometimes known as dry eye syndrome or dry eye disease), is a condition where the eyes are drier than they should be because they don’t make enough tears, or the tears evaporate too quickly.4 Dry eyes are common and can be temporary or chronic – meaning it stays with a person for life, often with periods where symptoms get better or worse, but never completely goes away.3,5

For most people it’s not serious, but if you’re reading this, then you probably know only too well that dry eyes can make you feel uncomfortable and not look your best. In severe cases, it can lead to complications such as infection, inflammation and damage to the eye’s surface (scratches, ulcers and vision loss).6 The good news is that there are plenty of things you can do to get some relief and avoid lasting damage.


Symptoms of dry eyes

A useful rule of thumb is that if you’re not able to keep your eyes open for 10 seconds or longer, you could have dry eyes. You may also notice one or more of the following symptoms:7

You might also experience: sensitivity to light, eye strain, feeling like there is something in your eye8 or more watery eyes than normal.

Did you know?

Oddly enough, having more watery eyes than normal is also a sign of dry eye.9 This is because if your tears don’t contain the right balance of water, electrolytes, mucus and fatty oils, the body can overcompensate by producing too many tears.

Causes of dry eyes

Dry eyes are very common! Up to 100 million people are thought to be affected globally,10 including 1 in 4 in the UK.11 Anyone can develop dry eyes, but you’re most at risk if you:12

  • Are going through, or have gone through, the menopause
  • Wear contact lenses
  • Use screens for extended periods without breaks
  • Are aged 50 and above

Genetics, hormones, environment, irritants, lifestyle, pre-existing health conditions, eye surgery and certain medications can all play a role too.13,14

Treatment

Treating dry eyes can be as simple as topping up your tears. Eye drops, such as Cationorm® can boost your body’s own natural protective layer of tears, rehydrate and quickly relieve discomfort.

You can also try lifestyle changes to prevent your eye’s natural tears from evaporating so quickly, such as:

  • avoiding windy or very dry conditions,
  • limiting use of air conditioning,
  • taking regular breaks from using computer screens,
  • using a humidifier and reducing intake of alcohol can be helpful.15,16
