The normal tears are formed of three layers: an oily (lipid) layer; a watery (aqueous) layer; a sticky (mucous) layer. All three work in harmony to protect, nourish and moisturise the eyes. Also, they refract or concentrate the light to help us see better. When we blink, which we do roughly every 4-6 seconds, our tears are refreshed.
Dry eyes occur when there are not enough good quality tears to lubricate the eyes. The medical term for it is keratoconjunctivitis sicca and can be classified into two main types:
As a general rule, if eyes are drier in the morning after the eyes have been closed overnight then blepharitis/meibomian gland dysfunction could be the root cause. If the eyes become dry throughout the day, then a lack of or increased evaporation of tears from the surface of the eyes is the cause.
To help prevent symptoms recurring use the eye drops regularly throughout the day and on an ongoing basis.
