First, you will need to understand that our tears are very important once and for all vision. The first thing light hits when it reaches the could be the tear film on the outside of your cornea. The cornea is like leading window for the eye along with the tears can be like a polish on that window. With each blink, the eyelid spread a smooth layer of tears throughout the cornea. This light might be focused by the cornea and lens to the retina, forming a graphic. When the tears dry up for the cornea, they leave a bumpy, irregular surface that distorts the sunlight entering the eye and makes all the image blurry. If the tears are continually blow drying between blinks, the top of cornea becomes constantly irregular on account of dead and dying corneal surface cells. This often triggers a reflex

best contact solution for dry eyes to create a lot of tears, so many our tear drain system is overwhelmed as well as the tears drain down our face. When we see this inside the clinic, we diagnose dry eyes.
Our tears include 3 components: oil, water and mucus. The watery part is manufactured mainly inside lacrimal gland which is inside upper outer a part of our eye socket within the upper eyelid. There will also be many smaller glands on the insides of our own eyelids. The skin around the inside of our eyelids makes mucus and rows of glands on our eyelid margins, just behind the eyelashes, make the oil. All three of these components need to be present in the right amounts to make tears work. Without water, the tears gum up and also you get eye matter. Without oil, the tears normally dry out very rapidly between blinks. Without mucus, the tears are far too thin , nor cover the eye well.
This brings us towards the causes of dry eyes:
Lack of tear production. This happens because of age, inflammation in the tear glands (such as in Sj?�gren syndrome ), hormonal changes causing less production and decrease of reflex tearing.
Excessive tear evaporation. Excessive evaporation can take place because of tears having inadequate oil (usually because of blockage with the oil ducts) and not blinking enough (common with all the computer or reading).
Eyelid problems that avoid the tears from being where they need to be. Eyelid problems also result in dry eye. These include poor blink as a result of a facial nerve problem (i.e. Bell’s palsy, facial or head injury), eyelid deformities, eyes not closing after over-aggressive eyelid lifting, along with cases where your eye area protrude, for example thyroid eye disease.
So what may be done regarding it?
Get properly diagnosed by an ophthalmologist to know dry eyes. They will do that by considering your vision using a microscope, analyzing your tears with special drops and also other tests, and taking a look at the health of your respective corneal surface. They will likely examine the eyelids to ensure you blink and close a persons vision appropriately.
Use artificial tears. Nearly all forms of dry eyes benefit from extra tears. They need to be used often, a minimum of 4 times daily or over to each 10-30 minutes in severe cases. There are many different viscosities of tears. The thicker they are, the longer they’ll last, but thicker tears usually blur the vision for a time after they are given. Tear ointments may also be helpful, especially in the evening as they possibly can significantly blur the vision when used throughout the day.
Keep your natural tears around longer. Plugs that block over tear drains with your eyelids help keep you against swallowing away those tears while they drain into your nose. In more severe cases, we sometimes permanently close off of the tear drains, that may greatly improve a persons vision surface. Your natural tears may be enhanced if you take omega-3 supplements.
Practice good eyelid hygiene. Warm compresses about the eyelids to helps oils to circulate out quicker in the tears. Lid scrubs with mild baby shampoo and domestic hot water across the eyelash margin will likely keep your oil flowing and keep matter from accumulating inside eyelashes.
Prevent excess evaporation. Blocking out moving air can reduce evaporative tear loss. This is done by close fitting sunglasses in the daytime and in many cases special moisture goggles to bed through the night. Avoid sleeping with a ceiling fan or blowing the environment conditioning at up your eyes while driving.
Reduce or eliminate contact lens wear. Contact lens wearers can use tears or “re-wetting solution” to keep your eyes more moist and improve lens wear comfort. Never use them overnight and clean them often, whatever the lens manufacturers say.
In special cases, treat inflammation. In a small number of people with inflammation with the tear producing glands, eye drops like Restasis might help produce more tears. In my view, this drugs are over-prescribed with this country and few patients truly obtain a reap the benefits of it, so caveat emptor.
Dry eye is common and annoying, but might be readily treated and might enhance your vision and overall eye comfort.
