DRY EYE

DRY EYE
To my regular readers…Hey Gang!…Thanks for stopping by again,
Thanks to you first timers too!
As promised, here is another article regarding Eye Health.

DRY EYE: An Irritating Problem

If your eyes often feel dry and scratchy, you may have a condition called dry eye.
This occurs when the eyes are not kept moist enough by tears.
Dry eye can be uncomfortable. It raises your chances of eye infection. Left untreated, dry eye can cause serious damage to the eye issue. Over time, the cornea (the eyes protective covering) could even become scarred, resulting in vision loss.
Dry eye can also make wearing contact lenses very uncomfortable.

If you have dry eye, you'll be glad to know that this condition can be treated. This article will help you understand how.

Symptoms of Dry Eye

Dry eye can cause one or more of the following symptoms:

1 watery eyes
2 scratchy, dry, irritated or generally uncomfortable eyes
3 redness of the eyes
4 a feeling of the presence of a foreign body in the eye
5 blurred vision
6 and apparent loss of the eyes normal clearness and luster


Two types of tears

Normally, the eye is lubricated by tears. These lubricating tears are made by a gland in the eyelid. (These are different from the more watery reflex tears that are made when you cry.) Every time you blink, lubricating tears spread over the surface of the eye.
They then flow out of the eye and drain into the nose.


The Anatomy of a Tear

Lubricating tears form of film on the eye.
This keeps the I moist. These tears have three layers that work together to lubricate the eyes.



When You have Dry Eye

Dry eye is caused by a problem with the lubricating tears. In some cases, not enough tears are made to moisten the eye. In others, enough tears are made but they don't have the right amounts of each layer to work right. The tears may be to watery or too sticky to properly lubricate the eye.

When the cornea is irritated, the body tries to fix this by making more tears. So, dry eye can actually cause your eye to water. But since these tears aren’t able to properly lubricate the eye, making more of them doesn't solve the problem.


Causes of Dry Eye

Dry eye can be caused by one or more of the following:

1 Age. As a person gets older, the eyes don't make tears as well as before. More than half of the people who have dry eye are over age 50.
2 Blinking problems. When you can't blink normally, your eye doesn't stay as moist.
3 Certain medications, including antihistamines, decongestants, birth-control pills, and tranquilizers.
4 Environmental factors, such as a dry climate or excessive exposure to wind.
5 Allergies or hayfever
6 Chemical or thermal burns to the eyes.
7 Certain health problems, including arthritis and Sjogren's syndrome (an autoimmune condition that affects mostly middle-aged women).


To Diagnose Dry Eye

Early detection of dry eye leads to more effective treatment and helps prevent damage to your eyes. If you have had symptoms of dry eye, make an appointment with your eye doctor. Your eyes will be examined using sophisticated diagnostic tools. You and your doctor will also discuss lifestyle habits, environmental factors, medications, and health conditions that could be causing your symptoms. Your examination and this discussion help your eye doctor determine the best form of treatment.

To Treat Dry Eye

Dry eye cannot be permanently cured, but there are effective treatments. Your eye doctor may recommend one or more of the following:


1 specially formulated eye drops (called lubricating eye drops or visual tears) which replaced your natural lubricating tears.
2 Soothing eye ointments that can be applied at bedtime.
3 The use of a humidifier in your home or office during periods of especially dry weather.
4 The insertion of tiny plugs in the tear drainage canal in the inner corner of each eye for more severe cases of dry eye. Visa slowdown in the drainage of tears from the surface of the eye. This way are tears remain on the eye longer and provide more natural lubrication. The plugs are inserted during a simple, painless procedure.
5 Surgery to permanently close the drainage Canal's in rare cases of dry eye. The surgery is simple and painless.

Allergies and Your Eyes

To my regular readers, sorry it has been awhile since I posted an article.
Last season's hurricanes caused things to be a little topsy-turvy for a while, but things are back to normal now, just in time for the new hurricane season. LOL

I know my blog is primarily intended to be about safety glasses, designer eyewear, and new eyewear products, but here in the very near future I'm going to be throwing in some articles in regards to your eye health as well as eyewear. So here's the first one, I figured it was a good time of year to discuss this topic.
Enjoy

The Problem With Allergies

Allergies can be triggered by many substances.
Seasonal allergies (also called hayfever) are often caused by the grass,
tree, and weed pollens that are abundant in spring and late summer.
Other types of allergies can affect your eyes year-round. Allergy symptoms include
sneezing, congestion, and red, watery, itchy eyes.

Why Allergies Occur

Your body's immune system protects you against illness by staying alert for harmful agents entering the body. If this occurs, the immune system protects you by neutralizing, removing, or destroying the harmful agent.

Allergies occur when the immune system misidentifies a normally harmless substance, such as pollen or mold, as a harmful agent. The body responds by producing more of certain chemicals to neutralize the substance. These chemicals, called histamines, are what caused the itchy, redness, swelling, and irritation you experience.

Many substances can trigger an allergic reaction. Most allergens that cause eye symptoms are airborne. Plant pollen, mold, dust, and animal dander (skin particles) are the allergens that most often affect the eyes.

Allergies can lead to a condition called allergic conjunctivitis. This is an inflammation of the conjunctiva (the membrane that covers the inside of the eyelid and the white part of the eye). It may occur at about the same time each year, when the allergen is most abundant

Relief for Irritated Eyes

Short of completely avoiding the allergens that cause your symptoms, it's impossible to escape your allergies. However, you can take steps to relieve your symptoms:

1. Try over-the-counter products such as antihistamine eyedrops to reduce redness, itchiness, and other symptoms. Artificial tears can also help by flushing allergens out of the eyes these products are available at drugstores.

2. When possible, limit your exposure to allergens. Stay inside when pollen or mold counts are especially high.

3. For cleaner indoor air, use air-conditioner filters that are designed to reduce allergens in the air.

4. Ask your health-care provider about other options. For example allergy shots may reduce symptoms and the need for other medication. Prescription medications may also be available.

Just throwing in a little bit of a disclaimer there.
This article is just to give you a bit of an overview in regards to allergies, if you think you may have allergies than please consult your physician.
