Healthy tears are vital to your eyes functioning correctly. Your tears are a very important part of your eyes immunity, cleaning system and optical pathway. When your eyes are dry you may experience:
There are three important layers in our tears. They must all be present in balanced quantities for our tears to effectively moisturise the eyes.
The innermost layer that sits against the cornea is the mucin or mucous layer. Next is the aqueous layer which is made of water and is secreted by the lacrimal gland. The outermost layer is made of oil and is secreted by the meibomian glands. It is generally the oil layer that is deficient in Blepharitis. Appropriate treatment of dry eye will help to restore all of the layers of the tear film to a normal healthy state so that you can return to having comfortable eyes again.
Artificial tears will work to both relieve your symptoms and also to improve the overall health of your tears. There are many different types of tear drops that vary in their viscosity, preservative formulation and other components. Your Ophthalmologist will recommend drops that are best suited to you.
