Got Dry Eyes? Here Are 3 Reasons Why and 7 Ways to Treat It
First, you will need to realize that our tears are important once and for all vision. The first thing light hits when it reaches your eye may be the tear film on the outside of your cornea. The cornea is like the leading window to the eye as well as the tears can be like a polish on that window. With each blink, the eyelid spread an even layer of tears throughout the cornea. This light is then focused with the cornea and lens to the retina, forming a graphic. When the tears normally dry out about the cornea, they leave a bumpy, irregular surface that distorts the sunlight getting into a person’s eye and helps to make the image blurry. If the tears are continually drying out

This often triggers a reflex to produce lots of tears, numerous our tear drain method is overwhelmed and the tears drain down our face. When we see this in the clinic, we diagnose dry eyes.
Our tears include 3 components: oil, water and mucus. The watery part is created mainly in the lacrimal gland that’s inside the upper outer section of our eye socket beneath the upper eyelid. There may also be many smaller glands for the insides of our eyelids. The skin on the inside of our eyelids makes mucus and rows of glands on our eyelid margins, just behind the eyelashes, make oil. All three of these components need to be present within the right comes down to make tears work. Without water, the tears gum up so you get eye matter. Without oil, the tears normally dry out very quickly between blinks. Without mucus, the tears are too thin and do not cover the eye well.
This brings us on the causes of dry eyes:
Lack of tear production. This happens because of age, inflammation of the tear glands (including in Sj?�gren syndrome ), hormonal changes causing less production and decrease of reflex tearing.
Excessive tear evaporation. Excessive evaporation can occur due to tears having inadequate oil (usually on account of blockage in the oil ducts) rather than blinking enough (common while using the computer or reading).
Eyelid conditions steer clear of the tears from being where they must be. Eyelid problems also result in dry eye. These include poor blink on account of a facial nerve problem (i.e. Bell’s palsy, facial or head injury), eyelid deformities, eyes not closing after over-aggressive eyelid lifting, as well as in times when your eyes protrude, like thyroid eye disease.
So what could be done regarding it?
Get properly diagnosed by an ophthalmologist to know dry eyes. They will make this happen by considering the eyes which has a microscope, analyzing your tears with special drops and also other tests, and taking a look at the health of one’s corneal surface. They will likely examine the eyelids to ensure you blink and close a person’s eye appropriately.
Use artificial tears. Nearly all forms of dry eyes take advantage of extra tears. They need to be used often, at the very least 4x daily and up to each and every 10-30 minutes in severe cases. There are many different viscosities of tears. The thicker they may be, the longer they’ll last, but thicker tears have a tendency to blur the vision for a while after they’re given. Tear ointments are also helpful, especially during the night as they are able significantly blur the vision when used throughout the day.
Keep your natural tears around longer. Plugs that block from the tear drains within your eyelids could keep you from swallowing away dozens of tears because they drain into your nose. In more severe cases, we often permanently close off of the tear drains, which may greatly improve the eye surface. Your natural tears may be enhanced by taking omega-3 supplements.
Practice good eyelid hygiene. Warm compresses around the eyelids to helps oils circulation out with less effort in to the tears. Lid scrubs with mild baby shampoo and warm water down the eyelash margin may also keep your oil flowing whilst matter from accumulating inside 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 the daytime and even special moisture goggles to bed in the evening. Avoid sleeping with a ceiling fan or blowing the air conditioning at the eyes while driving.
Reduce or eliminate contact wear. Contact lens wearers may use tears or “re-wetting solution” to help keep the eyes more moist and improve lens wear comfort. Never wear them overnight and clean them often, it doesn’t 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 within this country and few patients truly have a benefit from it, so caveat emptor.
Dry eye is typical and annoying, but may be readily treated and may even enhance your vision and overall eye comfort.
