Got Dry Eyes? Here Are 3 Reasons Why and 7 Ways to Treat It
First, it is very important realize that our tears are very important once and for all vision. The first thing light hits if it reaches the could be the tear film on top of the cornea. The cornea is a lot 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 a smooth layer of tears through the cornea. This light is then focused with the cornea and lens on the retina, forming a graphic. When the tears dry out for the cornea, they leave a bumpy, irregular surface that distorts the lighting coming into the attention and makes all the image blurry. If the tears are continually becoming dry between blinks, the top of cornea becomes constantly irregular as a result of dead and dying corneal surface cells. This often triggers a reflex to create a lot of tears, countless which our tear drain product is overwhelmed and also the tears drain down our face. When we see this in the clinic, we diagnose dry eyes.
Our tears are made up of 3 components: oil, water and mucus. The watery part is made mainly inside the lacrimal gland that is inside upper outer a part of our eye socket beneath the upper eyelid. There will also be many smaller glands on the insides individuals eyelids. The skin around the inside individuals eyelids makes mucus and rows of glands on our eyelid margins, just behind the eyelashes, increase the risk for oil. All three of these components need to be present in the right comes down to make tears work. Without water, the tears gum up and also you get eye matter. Without oil, the tears normally dry out very quickly between blinks. Without mucus, the tears are too thin and cover the eye well.
This brings us to the causes of dry eyes:
Lack of tear production. This happens due to age, inflammation from the tear glands (for example 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 insufficient oil (usually as a result of blockage from the oil ducts) rather than blinking enough (common with the computer or reading).
Eyelid conditions steer clear of the tears from being where they need to be. Eyelid problems also lead to 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, along with cases where your eyes protrude, such as thyroid eye disease.
So what could be done regarding it?
Get properly diagnosed by an ophthalmologist that knows dry eyes. They will do this by taking a look at your eyes with a microscope, analyzing your tears with special drops as well as other tests, and considering the health of the corneal surface. They will even examine the eyelids to ensure you blink and close the attention appropriately.
Use artificial tears. Nearly all varieties of dry eyes make use of extra tears. They need to be used often, no less than 4 times daily or more to each 10-30 minutes in severe cases. There are many different viscosities of tears. The thicker these are, the longer they’ll last, but thicker tears usually blur the vision for a time after they’re given. Tear ointments can also be helpful, especially at night as they are able significantly blur the vision when used throughout the day.
Keep your natural tears around longer. Plugs that block off the tear drains inside your eyelids could keep you from swallowing away all those tears as they drain to your nose. In more severe cases, we very often permanently close over tear drains, which could greatly improve a person’s eye surface. Your

Practice good eyelid hygiene. Warm compresses about the eyelids to helps oils to flow out with less effort into the tears. Lid scrubs with mild baby shampoo and warm water across the eyelash margin may also maintain your oil flowing and keep matter from accumulating inside the eyelashes.
Prevent excess evaporation. Blocking out moving air can reduce evaporative tear loss. This is done by wearing close fitting sunglasses throughout the day and even special moisture goggles to bed during the night. Avoid sleeping within ceiling fan or blowing the air conditioning at the eyes while driving.
Reduce or eliminate lens wear. Contact lens wearers are able to use tears or “re-wetting solution” to hold 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 can help produce more tears. In my view, this drugs are over-prescribed in this country and few patients truly get a take advantage of it, so caveat emptor.
Dry eye is typical and annoying, but can be readily treated and may even improve your vision and overall eye comfort.
