Dry Eye Syndrome

Dry eyes are a very common occurrence interfering with comfort and visual function and are more apparent in the winter season. It results from changes in volume (quantity) and chemical composition (quality) of the tear film leaving you with ocular discomfort.

The tear film

The tear film consists of 3 layers, each performing its own function to help keep the ocular surface stable, namely the outer lipid layer, the middle aqueous layer and the inner mucous layer. Failure of one of these layers can result in dry eyes, also known as Keratoconjunctivitis Sicca.

Classification of dry eyes

Deficient tears due to gland obstructions
Tear evaporation caused by contact lenses, lids, surface changes or lipid deficiency
