Dry Eye Syndrome

Our eyes need moisture to stay healthy and comfortable. The lack of tears lead to a condition called dry eye syndrome. There are two main dysfunction that lead of dry eye: lack of tears production or increased tears evaporation. Tears are a complex mixture of fatty oils, water, mucus and more than 1500 different proteins to keep  the surface of  the eye smooth and protected from environment, irritants and infectious pathogens. Tears form three layers:

  • Outer oily lipid layer - produced by the Meibomian glands to keep tears from evaporating too quickly

  • Middle aqueous (water) layer - produced by the main lacrimal gland to nourish the cornea and conjunctiva

  • Inner mucin layer - produced by the goblet cells to help bind water from the aqueous layer to ensure the eye remains wet. 

Causes of Dry Eye

  • Medications (antihistamines, decongestant, birth control, hormone replacement, anxiety meds, Dupixent)

  • Age - dry eye is more common in people over the age of 50 

  • Rosacea 

  • Blepharitis - inflammation of eyelids 

  • Meibomian gland dysfunction - cause of evaporative dry eye

  • Autoimmune disorder such as Sjogrens, lupus, rheumatoid arthritis, Vit A deficiency 

  • Women - hormonal changes and menopause have been linked to dry eye

  • Environment - windy, dusty, AC draft, ceiling fans can increase tear evaporation. 

  • Seasonal Allergies 

  • Extended digital device use can reduce blink frequency leading to dry eye
