Dry Eyes!!

Dry eyes is a condition many people confront.It is caused when the tears produced by the eyes are insufficient in moisture, lubrication, and other features that help keep the eyes remain protected.

It may also be stimulated by environmental aspects such as weather that irritate the eye and dry up tears. People with dry eyes often feel discomfort in a variety of forms including irritation, inflammation, or the feeling of something in the eye.

They are diagnosed by a doctor and repeatedly have a decrease in the amount of tear creation due to obstruction or just a minimisation in tears. They tend to have the uncomfortable feelings and symptoms for a longer period of time where as dry eyes for a person who works on a computer frequently may be more short term. Treatments for minor degrees of dry eyes may not be as efficacious for chronic dry eyes because of the deviating causes.

Tears are a major protective agent for the eyes as they not only wash away dust from the eyes, but also soothe the eyes, provide oxygen and nutrients to the cornea, as well as help defend against eye infections by removing microorganisms that can colonise in the eyes.

It also shows that dry eyes are more likely if there is a depletion of tears due to reduction of generation because of age or by weather issues like windy days which can dry out tears quickly. Women approaching menopause especially face dry eyes due to the increase in hormones.

Another factor is that some people are not able to generate as much natural tears as needed whether it be from aging, blockage of tear ducts, or from medication that leads to less yielding of tears. This problem oftentimes leads to chronic dry eyes
as the person is not able to manufacture tears and the eyes are not sufficiently lubricated. Tears evaporate rapidly, and the eyes are not cleaned properly.

Environmental factors can also play a factor in eyes drying up. Examples include dusty air, dry or windy weather, or fumes like cigarette smoke which can evaporate tears much speedily or hamper their effectiveness.

Contact lens wearers usually experience dry eyes because they contacts seems to work against moisturization.A deficiency in vitamin A or insomnia may also lead to dry eyes.
