Dry eyes disease affects an increasingly large number of people. The condition occurs when tears do not lubricate the eye properly. This can happen when glands in the eye produce too few tears, or if the tears are poor quality.
Symptoms of dry eyes include burning, grittiness, pain, irritation, redness and inflammation, as well as flaky eyelids (blepharitis).
Dry eyes do not usually have one single cause. However, studies show that over 80% of dry eye disease is caused or worsened by meibomian gland dysfunction. In addition, spending too long looking at screens can be a major causal factor. So too is spending time in air conditioned environments like office towers or aeroplanes.
Treating the condition requires lifestyle changes as well as blinking exercises and non-invasive procedures designed to stimulate tear flow.
