Insight from the Arizona Eye Specialists: 3 Eye Care Myths Dispelled

Arizona eye specialists

As we bid adieu to January, National Eye Health month, Nationwide Vision’s leading Arizona eye specialists would like to take this timely opportunity to dispel common myths about eye health care. Comprehensive wellness starts with a solid understanding of how your eyes function, so hone your ocular understanding and clarify your outlook with this Arizona eye care insight.

Take if from us, the Arizona eye specialists – these three tall tales are works of fiction:

  • Your vision will be worsened by reading in dim light: False.
    This common misunderstanding goes hand in hand with another fallacy – that frequent squinting weakens your eyesight. Fortunately for late-night bookworms, both of these statements are incorrect. When there is inadequate light (or when you’re due for a new pair of glasses), squinting is quick common. By squinting, one’s eyes let in less light, making the pupils smaller and further enhancing the eyes’ focus. Those who squint often are not permanently damaging their vision, but may find themselves with a headache and, ultimately, wrinkles around the eyes. Consult your doctor if you find yourself squinting excessively – it may be time for a new pair of eyeglasses.
  • Eating carrots improves your eyesight: False.
    Although carrots are high in vitamin A, which is essential for good vision, carrots don’t contain enough of the nutrient to affect how well you read. Eat a balanced diet and consider taking a multivitamin daily to ensure your eyes have all the vitamin A necessary to function at full ocular capacity. If you are concerned about your vision or interested in perfecting your eyesight with a procedure like LASIK, visit your Arizona eye care provider today.
  • Staring at a computer screen is bad for your eyes: False.
    Children throughout Arizona can collectively say “I told you so!” Staring closely at the television or computer screen will not hurt one’s eyesight. Temporarily, however, it might incur a headache. Much of the problem stems from the screen itself, because people staring at a screen for extended periods tend not to blink. Normally, people blink about 15 times a minute. If you spend most of the day on a computer or watch a lot of television, be cognizant of your blinking. Blinking keeps the cornea from dying and stop dust and debris from collecting in the eye.

Is Your Child Ready for Contacts?

In: Eye Health comments

You have heard the same story over and over again for the last three months. “Mom, can I please please get contacts? I promise I’ll take care of them!” Sure, you heard the same story when your daughter begged you to let her get a dog three years ago. Now you might as well add “Professional Dog Caretaker” to your resume. Still, you can tell your daughter really does not like her glasses, and her self-esteem seems to be suffering because of it. How do you really know when to make the transition from glasses to contacts?

Believe it or not, age usually is not the most important factor when considering whether your child should begin the transition to wearing contacts. Most eye doctors first ask you to assess your child’s level of responsibility. Does your child wash their hands, shower, do their chores and complete their homework without needing reminding? See how your child’s level of maturity compares with their motivation for contacts. If they truly want contacts, they may put in the effort to properly care for them, regardless of their past actions.

Consider as well the level of your child’s happiness. Some children may develop low self-esteem with wearing glasses, particularly as they enter into their middle school years. Unfortunately, your child may also be subject to some unfriendly comments from classmates and peers as a result of needing to wear glasses. If using contacts instead results in a significantly higher level of confidence for your child, it may be worth taking the next step in the process.

Fortunately, the next step is a painless one! At Nationwide Vision, we have contact lens professionals available at any of our 63 locations. These individuals can help you and your child consider all components and questions, in additional to developing a plan that works best for everyone. Schedule an appointment at a location near you today!

Why Your Child Should Receive an Annual Eye Exam

by

In: Eye Health comments

Being a mom means so much more than the title suggests. Moms have the skills of a chef, the endurance of a marathon runner, and have enough patience to fill a dozen virtues. Moms juggle more schedules than most circus performers, making sure everyone makes it to play dates, piano practice and the dentist clean and on-time. With an already hectic schedule, it’s hard to imagine adding an annual eye exam to the list. What you may not know is a comprehensive eye exam can reveal potential medical conditions, before any outward symptoms become noticeable.

For children, an eye exam can reveal the early on-set of either Type 1 or Type 2 diabetes. With November being Diabetes Awareness Month, we want to share with you why your child may not be immune. Currently, one in every 400 children and adolescence in the US have diabetes, and the number continues to grow annually. Type I diabetes does not result from poor diet and exercise, but rather from the pancreas’ inability to metabolize insulin properly. That means even a child who lives a healthy lifestyle can still have diabetes. Regardless of the cause, both Type I and Type II diabetes have similar symptoms, including extreme thirst, drowsiness and sudden weight changes among others.

What does this have to do with an eye exam? Because the eyes are so sensitive, the signs of diabetes often reveals themselves first inside the eyes. High insulin levels begin causing slight damage to the blood vessels within the retina, giving optometrists a warning before your child begins noticing symptoms. If diagnosed early, a treatment plan can begin long before the disease begins to spiral out of control. If your child has already received a diagnosis, an annual eye exam is essential for monitoring the progression of damage to the retina, a condition called Diabetic Retinopathy.
In addition to diabetes, an annual eye exam can reveal other medical conditions. For example, clots in the tiny blood vessels inside of the retina can be a signal risk for strokes, while thickened blood vessel walls along with narrowing of the vessels can be a sign of high blood pressure. Puffy eyes may mean you have an allergy, or may have consumed too much sodium. Yellowing of the eyes may be sign of hepatitis, gallbladder disease or likely a gall stone block.

With enough to worry about as it is, an annual eye exam will most likely simply put your mind at ease, allowing you to concentrate on the joys of simply being a mom!

I Always Cry at Onions

by

In: Random comments

It’s said that whenever George Washington felt a cold coming on, he would eat an onion, believing it would help keep the illness away. If nothing else, it would keep meetings shorter. Onions can enhance many recipes, but getting them there can make a grown man or woman cry.  Interestingly, the same compound, scientifically termed syn-propanethial S-oxide, that makes you cry when cutting up onions also gives them their great taste. The question is, why does cutting onions make our eyes tear up?

Watch out, we’re going to hit you with some science! Sulfides are converted to syn-propanethial S-oxide enzymes called allinases, which are released when the cells of the onion are damaged by the blade of your knife. This potent lachrymatory agent is then released as a gas which causes the stinging sensation in our eyes, followed by all those tears. Whew! We made it.

There are several steps you can take to minimize the tear-jerking effects.

  1. By using a sharp knife, you will slice through the onion rather than crushing it, causing fewer of the tear-creating enzymes to be released.
  2. Putting onions in the freezer 15 minutes before you cut them can help reduce the amount of enzymes released.
  3. Wear tight goggles or a mask.  Yeah, it seems a little weird, but it will protect your eyes.  Pretend you’re slicing onions on a mission to Mars.
  4. Slice them near an exhaust fan, or have a fan blowing on the onions while you’re cutting them to prevent the enzymes from rising.
  5. Cut them under water!  That way, the water will catch the enzymes before they ascend.
  6. Put vinegar on your cutting board or soak the onion first in salt water.
  7. Have a lighted candle next to your cutting board. The open flame will attract the enzymes, instead of bringing them to your eyes.

Other suggestions include whistling while you work (which blows the fumes away) or chewing gum.  In any case, now you have several options to try out the next time chopping onions are called for in a recipe. Let us know which one works best for you!

Don’t Take a Hydration Vacation

Drink more water!

You’ve heard these words before, but many not have paid as much attention to them as you should. Water makes up half our body weight and is crucial to our well-being, particularly in our dry Arizona climate.  Let’s be clear—soda pop and coffee contain water, but plain, old H2O is what keeps the machine well oiled.

Have you grabbed for your water bottle yet? Think about it—your body expects water.  It needs water to function, to maintain the proper temperate, remove waste, lubricate your joints, etc.

So, you think you’re drinking enough water, right?  Here are symptoms of not having enough of it in your system

  • - Little or no urine, or urine that seems darker than usual
    - A dry mouth
    - Constant sleepiness or fatigue
    - Thirsty all the time
    - Headaches
    - Feeling dizzy or lightheaded
    - No tears when crying
    - Dry eyes

I personally experienced what happens when you don’t drink enough water years ago when I got up in the middle of the night to go to the restroom and passed out.  Fearing the worst, I went to the doctor’s office to find out what’s wrong and after examining my daily routine, it was determined I just wasn’t drinking enough water.  I was among those thinking coffee should suffice.

Back in the days of wearing contacts, I relied on eye drops to keep my constantly dry eyes moist and “less scratchy.”  Then, when I focused on drinking more water during the day, I found I had less of a need for them.

A good way of increasing your daily water intake is to set a goal, a measurement. Fill up a water bottle every morning at work and be sure to finish it before you go home.  If you prefer bottled water, make sure you knock down at least two of them before calling it a day. You should drink around 48 ounces of water per day.

I think you’ve got it by now.

The bottom line: We go back to where this whole post started—Drink more water.

Eyes: The Windows to Your Health

by

In: Eye Health, Health and Wellness, Medical comments

The human body’s system is what we call “interconnected,” meaning that changes in one part of our body, such as our eyes, can actually mean that there’s a change with another part of our body. By having a comprehensive eye exam, your doctor may be able to spot a medical condition early, and begin a treatment plan before it starts to affect you.

Since the eyes live on the surface of our bodies and are see-through, blood vessels, nerves and tissues can be easily viewed with specialized equipment. This allows doctors to be the first to spot certain medical conditions with just a simple eye exam. There are a few medical conditions that doctors are able to spot based on what your eyes look like, or how they react to different light. Clots in the tiny blood vessels inside of the retina can be a signal risk for strokes, while thickened blood vessel walls along with narrowing of the vessels can be a sign of high blood pressure. Puffy eyes may mean you have an allergy, or may have consumed too much sodium. Yellowing of the eyes may be sign of hepatitis, gallbladder disease or likely a gall stone block.

Because the eyes are always changing, Nationwide Vision strongly recommends everyone receive an eye exam on an annual basis. Having said that, adults with no symptoms or known risk should minimally get a base line exam by age 40, and should return every 1-3 years for evaluation until their mid-60’s.  To help ensure healthy vision and overall health, adults 65+ need to receive a comprehensive eye exam annually.

Aside from getting your comprehensive eye exam regularly, make sure and eat these foods for optimal eye health; blueberries, leafy greens such as kale and spinach, peas and apricots.

Carrots and Your Eye Health

by

In: Eye Health, Health and Wellness comments

So you’re saying that if I eat a bunch of carrots I’ll have perfect vision?  Not exactly, but eating carrots does improve your vision in some ways, thanks to the large amount of Vitamin A they contain.

Carrots are rich in what we call beta-carotene, an important precursor to vitamin A. Although keeping your vitamin A levels up may not increase your vision to a perfect 20/20, but it can help to convert the light that enters your eye into nerve signals which allows you to see better in lower light (dark) situations. On the other hand, extreme deficiencies in vitamin A can have detrimental effects on your vision, including blindness.

Carrots aren’t the only vegetable or food that contains a high source of beta-carotene.  Other orange-colored foods such as mangos, pumpkins, cantaloupes and sweet potatoes are also great sources of beta-carotene.  Fruits and veggies aside, this nutrient is also prevalent in dairy products such as milk and cheese, as well as egg yolks and liver.

Like other nutrients such as fat, sodium, cholesterol, etc., be careful how much beta-carotene-rich foods you eat.  Since beta-carotene is a pigment, it may cause your skin to become orange.  This hasn’t proven to be harmful, but we recommend consulting a doctor if this happens to make sure you’re consuming a balanced diet.
