The majority of us do not realise that we have often experienced the symptoms of this condition.
Dry eyes is certainly the most common eye condition and the incidence is increasing rapidly.
Hundreds of little glands in the lids and conjunctiva have to contribute to its formation in a controlled way. We blink our eyes regularly to maintain this complicated layer. It lubricates the eye and lid movements and provides the clear corneal surface that makes vision possible to mention only two of its many functions. If the tearfilm does not function properly, dry spots develop producing friction between the eye surface and the lid which causes grittiness, burning, tearing etc. Increased friction between eye and lid makes the eye and lid muscles work harder causing them to ache and the lids to droop.
