First, it is important to realize that our tears are necessary for good vision. The first thing light hits if it reaches your talent may be the tear film on the outside of the cornea. The cornea is much like top window on the eye along with the tears can be like a polish on that window. With each blink, the eyelid spread an even layer of tears across the cornea. This light might be focused with the cornea and lens on the retina, forming an image. When the tears normally dry out about the cornea, they leave a bumpy, irregular surface that distorts the light coming into the attention and helps make the image blurry. If the tears are continually blow drying between blinks, the surface of the cornea becomes constantly irregular because of dead and dying corneal surface cells. This often triggers a reflex to generate lots of tears, so many which our tear drain method is overwhelmed and the tears drain down our face. When we see this within the clinic, we diagnose dry eyes.
Our tears contain 3 components: oil, water and mucus. The watery part is manufactured mainly inside the lacrimal gland that is inside upper outer section of our eye socket within the upper eyelid. There may also be many smaller glands about the insides of our eyelids. The skin for the inside of our own eyelids makes mucus and rows of glands on our eyelid margins, just behind the eyelashes, make the oil. All three of these components have to be present inside the right depends upon make tears

work. Without water, the tears gum up and you also get eye matter. Without oil, the tears dry up very quickly between blinks. Without mucus, the tears are far too thin and do not cover a person’s eye well.
This brings us for the causes of dry eyes:

Lack of tear production. This happens as a result of age, inflammation with the tear glands (such as in Sj?�gren syndrome ), hormonal changes causing less production and loss in reflex tearing.

Excessive tear evaporation. Excessive evaporation may appear because of tears having too few oil (usually because of blockage of the oil ducts) rather than blinking enough (common when using the computer or reading).

Eyelid problems that prevent the tears from being where they should be. Eyelid problems also result in dry eye. These include poor blink because of a facial nerve problem (i.e. Bell’s palsy, facial or head injury), eyelid deformities, eyes not closing after over-aggressive eyelid lifting, and in times when your eyes protrude, for example thyroid eye disease.

So what could be done about this?

Get properly diagnosed by an ophthalmologist who knows dry eyes. They will do this by looking at your vision with a microscope, analyzing your tears with special drops along with other tests, and taking a look at the health of your respective corneal surface. They may also examine the eyelids to ensure you blink and close a persons vision appropriately.

Use artificial tears. Nearly all types of dry eyes benefit from extra tears. They need to be used often, at the very least four times daily or over to every 10-30 minutes in severe cases. There are many different viscosities of tears. The thicker they’re, the longer they’ll last, but thicker tears often blur the vision for quite a while after they may be given. Tear ointments may also be helpful, especially at night as they can significantly blur the vision when used during the day.

Keep your natural tears around longer. Plugs that block from the tear drains inside your eyelids could keep you swallowing away dozens of tears since they drain into the nose. In more severe cases, we quite often permanently close from the tear drains, which could greatly improve a person’s eye surface. Your natural tears might be enhanced if you take omega-3 supplements.

Practice good eyelid hygiene. Warm compresses on the eyelids to helps oils to flow out easier into the tears. Lid scrubs with mild baby shampoo and tepid to warm water along the eyelash margin will also keep the oil flowing and keep matter from accumulating inside the eyelashes.

Prevent excess evaporation. Blocking out moving air is effective in reducing evaporative tear loss. This is done by putting on close fitting sunglasses in daytime as well as special moisture goggles to bed at night. Avoid sleeping within a ceiling fan or blowing air conditioning at the eyes while driving.

Reduce or eliminate contact lens wear. Contact lens wearers will use tears or “re-wetting solution” to keep the eye area more moist and improve lens wear comfort. Never use them overnight and clean them often, no matter what the lens manufacturers say.

In special cases, treat inflammation. In a small number of individuals with inflammation of the tear producing glands, eye drops like Restasis will help produce more tears. In my view, this drugs are over-prescribed with this country and few patients truly get yourself a reap the benefits of it, so caveat emptor.

Dry eye is common and annoying, but might be readily treated and may even improve your vision and overall eye comfort.
