What is Dry Eye?

Dry eye syndrome is a condition where the eyes do not make enough tears, or the tears evaporate too quickly. This can lead to the eyes drying out and becoming inflamed.10

It’s a common condition and becomes more common with age, especially in women. Up to a third of people age 65 or older may have dry eye syndrome and women are 50% more likely to experience dry eye syndrome.11

Dry eye is also more common in those with connective tissue disorders, such as rheumatoid arthritis12, in those with blepharitis (inflammation of the edges of the eyelids)10 and in the almost 4.1 million13 contact lens wearers in the uk.10

Dry eye can also be exacerbated by your environment – extreme weather conditions, air conditioning, central heating, smoking and too much screen time can all contribute to dry eyes.11

Symptoms can include:10

  • Feeling of dryness, grittiness, soreness
  • Tired eyes which get worse throughout the day
  • Mildly sensitive to light
  • Slight blurred vision
  • Both eyes are usually affected

Dry eye can have a significant impact on quality of life, which is why it’s important to treat the condition properly.14
