The Many Myths of Eye Care
Your eyes are an extremely important part of your body, but people may not be very aware of how they work. Unfortunately, there are many myths out there that we have heard, and we may believe them because we don’t know any better. Here’s an example: People that wear glasses become reliant on them. This is completely false.
All eyeglasses do is correct blurry vision. People may find after wearing glasses for a while that they prefer wearing them than not wearing them, but this doesn’t mean their eyes have grown reliant on eyeglasses. People who need eyeglasses to see clearly simply get comfortable with wearing their glasses and enjoying clearer vision – there is no such thing as developing a physical reliance on glasses.
All eyeglasses do is correct your vision, they don’t damage or “cure” it. People may say that wearing contact lenses can cure nearsightedness. There is no proof that this is true.
Another myth is that wearing the wrong glasses causes damage to your eyes. This is also false. If you have blurry vision but you lose your glasses, you shouldn’t worry about your eyes becoming damaged.
Not wearing your glasses simply will mean you’ll have blurry vision. If you wear an older prescription, your vision might not be as good, but your eyes are never damaged from these kinds of factors. Remember: Just because your vision is blurry or you have the wrong glasses doesn’t mean you’re harming your eyes. Instead, just get the right eyeglasses so you can enjoy clearer vision. That’s all.
We’ve also been told other myths that have been widely accepted by people, like eyes get damaged from reading in dim light or staring at computer screens. This is all untrue. Before the advent of electricity, people read by candlelight all the time, and their eyes weren’t adversely affected. Using your eyes in dim light doesn’t damage them, at all. It just strains them more, which is an important difference. When our eyes become strained, we’re more likely to feel tired, but this doesn’t mean we’re causing damage to our eyes.
The same idea goes with computer screens and televisions. Just like when your reading or sewing, your eyes are going to blink less often because you are focused on doing something. This means that less moisture is getting to your eyes. They can then feel tired, strained or out of focus, but you are not damaging them.
To prevent strain on your eyes, though, you can try a couple of things, like keeping your computer or television screen about two feet away from your face and making sure it’s at a slightly downward angle. If you’re eyes feel strained or out of focus, try taking your vision off of the screen and looking around the room, focusing on objects farther away. This will help you re-focus your eyes and relax them.
Another false fact out there is that people with weak eyes have to worry about wearing their eyes out. People hear this claim and they try to avoid fine print out of fear that they’ll “use up” their eyes. This is totally false. The eye isn’t a muscle; it’s more like a camera. You can use your eyes all you want, you won’t wear them out.
Other myths exist that claim people with crossed or misaligned eyes will just outgrow them. Unfortunately, this is a false claim, as well. People don’t outgrow these eye problems. Instead, it’s important for children with crossed or misaligned eyes to be treated by a doctor. The earlier they get treated, the better.
There are many ways to treat these types of eye conditions. For instance, if someone has a lazy eye, they might be advised to put a patch on their good eye, forcing the lazy eye to correct itself. There are many other types of treatment, like using eyeglasses, applying eye drops, undergoing corrective surgery or using a combination of these things.
Furthermore, despite what some may have told you, learning disabilities are not caused by eye problems. Being able to see and read clearly is separate from having a learning disability. Kids that have impairments in their learning functions will need special teaching, but it’s also important that they have clear vision. Because of this, every child should have a complete medical eye examination.
You may have also heard that “all eye doctors are the same.” This is also very untrue. There are two kinds of eye care providers: Ophthalmologists and optometrists. Ophthalmologists must have at least eight years of medical school and do extensive training in hospitals. They’re qualified for all kinds of eye care, like corrective surgeries. On the other hand, optometrists and opticians are trained to provide eye care services, but they aren’t licensed to do corrective surgeries.
It’s very important to be aware of the many debunked myths out there concerning eye health. No, carrots don’t “cure” your eyes. Vitamin A will help them, though, and you can find it in many different foods. You can sit as close to the television as you wish and you can read in the dark all you want. So be skeptic of the pseudo-facts people may tell you about eye health. If you ever have questions about maintaining your eye health or dealing with a vision problem, don’t hesitate to visit an eye care professional, who will give you all the reliable information you need.
Predicting Multiple Vision-Robbing Childhood Diseases with One Simple Test
In August of 2014, the American Academy of Ophthalmology announced a major breakthrough in the detection of ocular diseases that strike during childhood, causing visual impairment and even blindness. Researchers in the United Kingdom worked to develop the ground breaking testing procedure. A simple blood sample is needed for the new DNA test that can now be used to predict and diagnose several diseases at once. A specialize form of DNA testing that was originally used to detect congenital cataracts in children, has been found, with some modification, to be an effective diagnostic tool in detecting numerous obscure maladies of the eye.
The discovery makes diagnosis faster, cheaper, and easier, allowing doctors to start treating conditions early on and provide more effective, disease specific care. Since congenital cataracts can be a stand-alone problem, either as a f fluke mutation or due to a child’s mother being ill during pregnancy, or as a symptom of one of around 100 different ocular diseases, it has previously been difficult for eye care professionals to accurately pinpoint their root cause.
Specialized genetic testing is useful in determining the cause and in helping to narrow down an appropriate treatment for congenital cataracts. There is a set of 15 genes that the DNA test highlights with primers and uses as genetic markers. Mutations in these 15 different genes outline a patient’s specific condition. Some of the diseases linked to congenital cataracts include:
Down’s syndrome
Congenital rubella
Conradi syndrome
Ectodermal dysplasia
Galactosemia
Hallermann-Streiff syndrome
Pierre-Robin syndrome
Lowe syndrome
There are dozens of genetic diseases linked to congenital cataracts. Many of the conditions associated with congenital cataracts also affect other physical traits and cause a slew of functional issues. With quicker diagnostic abilities, physicians can provide patients and their families with genetic counseling along with the proper medical treatments.
Worldwide, between 20,000 and 40,000 children are born with congenital cataracts. Cataracts, of any kind, can lead to major problems with eye health. Special eye care is necessary to treat cataracts before they cause complete blindness. Congenital cataracts can show up immediately at birth or develop sometime during the early stages of childhood. When found in infancy, congenital cataracts can hinder proper development of vision. In some patients, congenital cataracts can appear only in the peripheral vision spectrum, or as a small patch in the central line of vision and therefore do not require surgery, however that is not typically the case.
Treatment for cataracts typically involves surgical removal of the top lens of the eye and the insertion of a manufactured lens. Depending on the ocular damage done by the cataract, even with surgery, some patients remain legally blind and still require corrective glasses. The more time it takes to treat cataracts, the worse the prognosis is for the patient.
Prior to this new testing breakthrough, time was not on the side of the doctors. Analysis of a patient’s condition typically involved collecting a detailed family history and running numerous tests in order to systematically cross off possible conditions, before finally coming to an inconclusive answer. Genetic testing of the 15 genes involved with congenital cataracts would normally take years. The new testing method allows for conclusive results within a matter of weeks instead of years.
Thirty-six cases were observed during the clinical trial study that took place in the United Kingdom. Out of the 36 cases, 75% of patients were given accurate, prompt diagnoses of their condition. The advanced test only takes two months to complete.
Currently, the congenital cataract DNA test is only offered in the United Kingdom. The nation began offering the service to infants and children with congenital cataracts in December, 2013. The test is also an effective way for potential parents with a family history of congenital cataracts to evaluate the risk to their children. Registered healthcare facilities around the world can request the congenital cataract DNA test through international referral, to help aid in eye care.
While the multi-use DNA test for congenital cataracts is in its early stages of use, researchers hope that the technology will have a far reaching impact on the field of Ophthalmology. Since the test has been useful in pinpointing the genetic markers and mutations that lead to the formation of cataracts, it is hoped that eye care professionals will one day discover the exact cause of age related cataracts. Identifying clear causes for ocular conditions is the first step in developing a treatment for them.
Taking Care of Contacts and Glasses
Whether you need to wear corrective lenses or contacts, regular care is necessary to promote longevity. Both contacts and glasses can be damaged or broken. In the case of contacts, this may not be a terrible ordeal, as these are worn temporarily in most instances. However, if you wear glasses, damaged or broken specs mean a trip to the eye doctors’ for a new pair.
To prevent something like that, you can take the proper precautions and take proper care of your contacts and glasses. If you wear contacts, care differs depending on the kind that you have. There are soft contact lenses and rigid gas permeable contact lenses (which have a tougher exterior). Then there are contacts that you throw out and those that you can keep for a longer amount of time, at least for a week but sometimes for up to a month.
If you have disposable contacts, you should never wear them beyond the extended amount of time as recommended on the box. If you have extended-wear contacts, you need to make sure that you also take them out nightly. If you wear them again, you need to clean them. You can typically find contact solution at the grocery store or at your eye doctors’ office. Don’t attempt to use water of any temperature to clean your contacts, as these could lead to the spread of bacteria. Only proper contact solution will clean your contacts properly.
If you forget to clean your extended wear contacts, you may want to skip wearing them again. They can easily attract bacteria which could infect your eyes. If you have any eye condition or an illness of any type (even one that doesn’t affect the eyes), you should switch to disposable contacts and throw these out after daily use. When your body is fighting off infection, bacteria is more likely to spread from your contacts.
However, perhaps you prefer wearing glasses instead. In that case, you need to worry not only about the lenses of the glasses potentially becoming damaged or broken but the frames holding up as well. If you’re an active person, you should not wear your glasses when playing sports. Instead, you may want to talk to your eye doctor about prescription sports goggles that are meant for activity. Whenever you’re not wearing your glasses, you should take them off properly, using both of your hands. This prevents you from tugging at one of the arms and loosening it or accidentally snapping it off.
You also need to place your glasses in a safe area when you’re not wearing them. Your glasses probably came in a hard-shelled case that you picked out at the eye doctors’ office. You should always place your glasses in that protective case when you’re not wearing them. You may want to put the case somewhere out of reach of kids or other people.
In order to keep the frames intact, look out for any loose parts. There are screws that hold together the frames which may unwind over time and need to be screwed back in. If you’ve noticed that the arms of your glasses are looser than usual, this should take care of the problem. If screwing the arms back in place didn’t help, you may want to take your glasses to your eye doctors’ office.
You also need to worry about the lenses of the glasses, which can experience damage in the form of scratching. Always placing your glasses in your hard-shelled case prevents them from coming into contact with other elements when you’re not wearing them. Put them with the arms against the back of the case rather than the lenses against the back of the case. If you need to take off your glasses for a moment and put them somewhere, never put the lenses first.
If you have a smudge or particles on your glasses that you need to wipe off, don’t just use your shirt, pants, or other fabric around you. Instead, use the cleaning cloth that your eye doctor likely gave you with your pair of glasses. This soft cloth will rub away any smudges without damaging the lenses.
By following these guidelines for contacts and glasses care, you will not have to worry about breakage, damage, and potential bacterial infection. As long as you don’t forget any of the above steps, you should be able to wear your contacts without incident, and enjoy your glasses for years ahead.
How to Alleviate the Discomforts of Eye Strain
In today’s technological world where people use screens often, eye strain has become more frequent. However, that’s not the only reason a person’s eyes may feel tired and unable to function like usual. If you go on a long road trip and you’re behind the wheel the whole time, if you work as a truck driver, or if you read for hours on end, you can also experience eye strain.
Most times, eye strain is not a serious medical condition. It doesn’t require intervention by a doctor and typically abates as long as you cease the strain-causing activity for a while. However, that doesn’t mean that eye strain doesn’t sometimes require medical attention if your symptoms get worse or do not disappear after some time.
First though, it helps to understand all sources of eye strain. Not only can staring too long on the road, reading for too long, or using computers or smartphones for too long cause eye strain, but so can other situations. For example, if you read or stare at something for too long in a room with poor lighting, your eyes will have a harder time functioning well. If the room is too bright though, you could also experience discomfort. Glare generated from screens or windows can also cause eye strain.
If you use a computer frequently for work, school, or recreation, this particular type of eye strain has its own particular name called computer vision syndrome. This syndrome isn’t very serious, like most types of eye strain, but it too can cause serious vision problems in some instances.
If your eyes begin straining, you’ll notice a few general symptoms. Your eyes will feel dry and may begin to hurt or itch. Your vision may begin to grow blurry and your eyes may also water. Your back, neck, and shoulders may begin to hurt, and you may notice that you have a headache as well. Other bright lights may make these symptoms worse. The symptoms for computer vision syndrome are generally the same.
However, in some serious instances, you may experience other symptoms. In these cases, it’s best to receive medical attention as soon as possible if these symptoms do not abate in a reasonable amount of time. You may have a strong headache or migraine, itchy or painful eyes, and double vision and other vision issues.
Some factors can make your eye strain worse, such as excessive air conditioning or heater use. If you’re already tired or have already had a long day, it shouldn’t take long for you to experience eye strain. If you already have eye issues such as refractive errors, this also increases your likelihood of developing eye strain.
If you do decide to visit with your doctor, he or she will test you for eye strain through a typical eye examination. You should discuss any factors that may cause your eyes to become uncomfortable, such as long amounts of time at a computer or on the road, long amounts of time spent reading, or possible preexisting eye conditions. Ultimately, if you have another eye condition, your doctor can treat it at this time. He or she may also recommend that you wear prescription lenses to reduce the chance of you developing further eye strain.
Mostly though, you can make most of the changes to prevent eye strain yourself. Take frequent breaks from reading or computer use. If you drive a lot, make rest stops when possible to give your eyes a chance to refocus and rest. Always make sure that you’re in a well-lit room and try to keep the temperatures even if you can. By moving your computer monitor at home and work between 20 and 40 inches from where you sit according to Mayo Clinic, you can reduce the effort your eyes have to make when looking at the screen. You should also try to prevent glare in the room if possible.
You can also buy artificial tears without a prescription if eye strain typically gives you dry eyes. These artificial tears keep your eyes lubricated so that your eyes don’t feel as irritated at the end of the day. You can try massaging your eyelid muscles, Mayo Clinic recommends. Rub your temple, your eyelids, your eyebrow muscles, and your cheek below your eyes using your fingertips for 10 seconds per spot. Try to do this at least once every day.
While eye strain isn’t a long-term threat to your vision, it’s still annoying and can detract from productivity and comfort. By taking the above steps to be proactive about your environment, you can reduce your chances of experiencing eye strain.
Understanding Allergic Conjunctivitis
Allergic conjunctivitis is a condition that makes the eyes red, itchy, and possibly watery. This condition occurs when the eyes are exposed to substances like pollen or mould spores. This condition is actually more common than most people realize. as it affects approximately one-fifth of the population. When your eyes get red, itchy, and watery it is just your body’s way of trying to get rid of a substance it considers potentially harmful.
Types of Allergic Conjunctivitis
There are generally two main types of allergic conjunctivitis, acute allergic conjunctivitis and chronic allergic conjunctivitis. These two types have the nearly the same symptoms and are very similar except that the acute version of this condition is short term and the chronic version is more long term.
Acute allergic conjunctivitis is more common of the two and generally occurs during allergy season. The unique symptoms of acute allergic conjunctivitis are swollen eyelids, itchy or burning eyes, and you may also experience a runny nose.
The much less common condition, chronic allergic conjunctivitis is something that can be experienced all year round. This is a response to things like food, dust, or animal dander. The most common symptoms of chronic allergic conjunctivitis are burning and itchy eyes, however, you may also experience some sensitivity to light as well.
What Are The Most Common Causes?
Your body decides that a foreign substance is a threat, so your body reacts in a defensive method which is known as allergic conjunctivitis. Any substance that triggers the release of histamine in the body will create this type of reaction. Histamine is a potent chemical that is naturally produced by your body to fight off any foreign and potentially harmful substances.
Some of the more common substances that cause this type of reaction are household dust, pollen from trees and grass, mould spores, animal dander, or chemical scents such as some detergents or perfume. Some people will also experience allergic conjunctivitis as a reaction to certain medications and such that are dropped into the eyes (like contact lens solution or medicated eye drops).
People who have allergies are much more likely to develop allergic conjunctivitis over time, however, it is more common in children and young adults rather than older people. Generally speaking, if you have allergies, and you live in an area that has a high pollen count, you are much more susceptible to allergic conjunctivitis than someone who does not have allergies or that does not live in such a high pollen area.
How Allergic Conjunctivitis Is Diagnosed
The first step to figuring out if you are dealing with allergic conjunctivitis is to have your eyes examined by your doctor. It is at this time that your eye care professional will likely go over your allergy history with you as well. The visible signs of conjunctivitis are redness in the white of the eye and/or very small bumps inside the eyelid. These little bumps are not something you will be able to see yourself, however, they are very irritating and may annoy you. Your eye care professional will be able to see these bumps with the assistance of the many tools they use during a regular eye exam to magnify the eye.
There are a few tests that your eye care professional may request you to undergo to ensure the condition is what he/she thinks it is. There is an allergy skin test which exposes your skin to specific allergens; consequently, your doctor will be able to examine how your body reacts to certain things. It is important to keep in mind that this test may result in swelling, redness, and some general discomfort.
Your eye care professional may require you to do some bloody tests to see if your body is producing the antibodies it needs to protect itself against specific allergens. The third test you may be asked to do is a scraping of the conjunctiva tissue. This type of test is done to evaluate your white blood cells. All of these tests may or may not be required, however, it is always a good idea to familiarize yourself with all the possibilities before jumping into a situation.
Treating Allergic Conjunctivitis the Natural Way
In an attempt to minimize the exposure you have to allergens, a combination of prevention strategies and activities are required. These methods will help to ease your symptoms and help you to get back to your life. If you live in an area with a higher pollen count, you may want to close the windows. Closing your windows will help you to keep the pollen outside where it belongs, outside.
You should try to keep your home as dust-free as possible. Dust is one of those things that never seems to want to let go of a home. You clean it and it returns the next day. If you have allergic conjunctivitis, and you want to ease your symptoms, it is important that you dust every day to avoid any dust build up. Additionally, if you use an indoor air purifier, you can ease the amount of allergens in your air.
Unfortunately, people who are prone to allergic conjunctivitis should avoid exposure to harsh chemicals such as hair dyes, paint, perfumes, or any other strong scent that may affect their condition. Unfortunately, rubbing your eyes will not help this situation. If you rub your eyes you will only make the issue worse. Should the itching and irritation get too much, you can ease some of the swelling and itchiness by placing a cool compress over your eyes for several moments.
Treating Allergic Conjunctivitis with Medication
Sometimes the allergic conjunctivitis is so severe that it is not curable with natural homeopathic remedies. When this is the case, medication may be necessary. Your eye care professional may tell you to take an oral, or over-the counter, antihistamine to reduce (or block) the histamine release within your body.
More commonly, anti-inflammatory eye drops, eye drops to shrink any congested blood vessels are more often used here. In the extremely rare case, steroid eye drops may be recommended. Should your eye care professional prescribe any of this to you, it is a really good idea to ask as many questions as possible and always follow the directions your eye care professional gives you.
