How hard could dry eye treatment be?
Many optometrists or ophthalmologists take the attitude that “if the eye is dry, then we need to wet it!” Unfortunately it is not that simple. In fact the so called mainstay of its treatment is lubricating eye drops, which believe it or not when used too frequently or inappropriately can actually make dry eyes worse!
Dry Eye disease or dry eye syndrome happens when the lubrication system of the eye breaks down. This can occur for many reasons, which is why dry eye is often referred to as a multifactorial disease.
Your eye is lubricated by your tear film. This sounds simple, but has been analysed by scientists and is extremely complex! NO eye drop on this planet can mimic the human tear film properly, which is why it takes more than dry eye drops to treat dry eyes.
Human tears are primarily made up of an aqueous (watery) component. This is produced by the lacrimal gland, which sits just under your eyebrow. This aqueous layer is mainly salty water. When the water evaporates in dry eye syndrome, the tear film becomes even saltier, which can cause the burning sensation that many people complain about.
