There are times you mIght feel you have sand in your eyes, or they might burn or itch, prompting the desire to scratch around your eyes intermittently. You might be sensitive to light, have blurry vision, or, in some cases, your eyes might water. And you may have a tough time wearing contact lenses. What all these point to is that you are having a problem called dry eyes syndrome. It happens because of a number of reasons. But don’t worry, just learn more about it and the solution to the problem. Continue reading….
The eyes need moisture
This helps them work the way they are supposed to and keeps them comfortable. Your body normally makes moisture for your eyes, but when you can’t, or it’s not good quality, this can make your eyes hurt and affect your eyesight.
What tears do for the eyes
They soothe the surface of your eyes and protect them from things like debris and infection. Each time you blink, they go over your eyes, then drain into the inner corners of your eyelids to the back of your nose. If you don’t make enough good-quality tears, your eyes can be dry and irritated.
Dry eye syndrome
The most common kind of dry eye happens because your body doesn’t make enough tears. This is called dry eye syndrome, or keratoconjunctivitis sicca (KCS). Many things can cause it. Depending on what that is, it can go away on its own or last a long time.
One of the possible causes of dry eye syndrome is age. The glands that make tears don’t work as well as you age, so you don’t make as many. Also, your eyelids begin to sag, and that can break the seal against your eyeball that helps keep in moisture.
Some other causes include:
(1) Certain Illnesses
Autoimmune diseases, that is when your immune system attacks parts of your body, can affect your body’s ability to make tears and cause dry eyes.
Examples include lupus and rheumatoid arthritis, as well as Sjogren’s syndrome, which attacks saliva and tear glands.
(2) Eye surgery
Dry eyes can be a side effect of cataract surgery and LASIK or PRK surgery, which correct vision problems. The nerves that help you make tears can be damaged during these procedures. Talk with your doctor about eye-drops and other things that can help. For most people, it gets better as your eyes recover.
(3) Evaporative dry eye
If your tears don’t have enough oil in them, they can evaporate (get absorbed into the air) before your eyes get enough moisture. This often happens when the glands that give your tears their oily texture are blocked.
Also called Meibomian gland dysfunction, it’s treated with warm washcloths and lid scrubs that clear away the dead skin, oil, and bacteria that can build up and plug the glands.
(4) Tear duct infection
Also called dacryocystitis, this happens when a tear duct, the small tube that runs down the length of your nose and connects to your eyelid, gets blocked and bacteria get in the area. It’s most common in infants, but it can happen at any age.
Symptoms include pain, redness, swelling, too many tears, discharge from your eye, and fever. Antibiotics are the most common treatment, but some people need minor surgery to clear it up.
If you have symptoms of dry eyes and take medication, read the label. Some drugs, such as antihistamines, beta-blockers, and some antidepressants, can affect your tears and dry out your eyes. Talk with your doctor to find out if this is a problem for you.
Other things that can make dry eyes syndrome worse
(A) Low humidity
If there’s not a lot of moisture in the air, for instance, in a heated or air-conditioned room or in an airplane, dry eyes can get even more irritated. And a lot of wind can do it, too (that includes riding a bike without protective eyewear).
(B) Too much screen time
Looking at a computer or phone screen for long periods of time can cause problems because you’re less likely to blink and get moisture over your eyes.
(C) Contact lenses
They sit inside the tear film, so when that’s dry, it can make it difficult and uncomfortable, even impossible, to wear them. Talk to your doctor if you’re having trouble with your contact lenses. It may help to change solutions or use lenses made from a different material.
What you can do about it
(1) Artificial tears
These aren’t the kind your toddler uses when he’s trying to get away with something.
These tears come from the drugstore as drops or ointment. Some have a chemical that can stop working if you use them too long, but not all have that. Talk to your doctor about what may work for you.
(2) Change Your Diet
Among other health benefits, omega-3 fatty acids also may help keep your eyes moist. The best place to get them is from fish like salmon, sardines, and mackerel. If you don’t like fish, you can take a supplement instead.
How to prevent dry eye syndrome
If your eyes are dry, it’s a good idea to stay away from some things that can irritate them, like hair dryers, air conditioning, wind, smoke, and some chemicals.
Use a humidifier, and take regular breaks if you spend long hours at a computer. During sports or outdoor activities, use swim or ski goggles or other protective eyewear, to help you keep moisture around your eyes.
When to see a doctor
If dry eyes are new to you and you’ve had them for more than a few days, talk with your doctor. It’s also a good idea to check with him before you use over-the-counter artificial tears.
In most cases, dry eyes are more of an annoyance than a health danger, but it’s always best to be sure.
The doctor will have a good talk with you, to understand the symptoms you may be experiencing and also take your medical history.
Based on this, he would recommend a course of action and may even conduct an eye test. You obviously love your eyes, so keep them healthy and they will be with you for life. Enjoy life, with your eyes, of course!
