Pumpkin pie, good for the eye!

29 11 2013

TheEyesofTexasBlog

Feeling a little guilt for all the food on Thanksgiving you ate?  Especially that piece or two of pumpkin pie?  I know my pants are feeling it.  But take heart, at least it’s good for your eyes!  Well, at least the pumpkin part.  Pumpkin is full of carotenoids, vitamins, minerals, and fiber.  This “superfood” I dare say is better than the mythical carrot.  So would acorn, butternut or other squash varieties.  Carotenoids in your diet from whole foods help reduce the risk of macular degeneration and delays cataract onset.   Of course, the whip cream, shortening, sugar and other ingredients may not be so great for your body.  Probably better to prepare them without all the cholesterol and sugar.

So, off to the gym I go to work off that pumpkin pie.  Hey, at least I can see the TV great while on the treadmill!

Attention shoppers! Beware the Blue Light Special!

21 11 2013

Who all remembers the Kmart commercials with the blue light bulb cartoon character advertising their “Blue Light Specials?”  For those not in the know, Kmart shoppers sometimes were able to buy certain items at a special price when the blue police light suddenly came on.  A voice would come over the P.A. system, “Attention Kmart shoppers, there is a blue light special on toilet paper on aisle 5 for the next 10 minutes!”   Then there might be a mad dash of crazed, bargain hunters to go get that item.

That’s not the blue light I am referring to however.   Humans see color in what is referred to as the visible color spectrum.   Basically, it’s the colors we see like in a rainbow.  You can remember them by using the mnemonic fictitious name, ROY G BIV.  He is not a radio personality or even a real person…at least I don’t think so.  Anyway, it’s a tool to remember the colors:  Red, Orange, Yellow, Green, Blue, Indigo, Violet.   All the guys are thinking, “What is Indigo?”   It’s basically dark blue, so unless you work at Sherwin-Williams mixing paint, it’s just trivia.

Some light is not visible to the human eye, such as Ultra-violet (U.V.) and Infrared, which is used in night vision goggles.  We all know the danger that U.V. can cause to the skin and eyes.  Blue light is next to violet and ultra violet light on the wavelength scale.

Over-exposure to blue light is becoming more and more of an issue with the eyes due to the use of electronic equipment and fluorescent lighting.  Research is showing it causes more eye and body fatigue with enough exposure. Some blue light is needed however, as it helps regulate our circadian body rhythms so we have regular sleep cycles.   Over exposure is the problem.

There is a new eyeglass treatment from Hoya Vision that helps reduce the amount of blue light we are exposed to everyday called Recharge EX3 AR.  It is a clear filter that restricts the more dangerous upper end (High Energy Visible or HEV) of the blue light spectrum.  It reflects the portion of blue light emitted from back-lit hand held devices that is “bad” and ensures the portion of blue light we need for optimal contrast and other health benefits is allowed to pass through.

 It makes your vision sharper, clearer and more comfortable when it is a part of your eyeglass lens.   Not a coating, it is a surface treatment that is part of the lens so it can’t peel off.  It reduces reflections and glare from light reflections, especially at night.  And, it’s been tested and certified by an independent lab to be as scratch resistant as glass!

Come by our office and visit with one of our opticians if you would like to see a demonstration lens and to learn more about this new product.

Until we can get someone to do something about those newer,  blinding, blue car headlights at night, this is JUST what the doctor ordered to help!

When the Moon Hits Your Eye….

19 11 2013

When I see the big full moon that sometimes occurs, I can’t help but think of Dean Martin singing, “When the moon hits your eye, like a big pizza pie….that’s amore!…”

What causes it to look so big?  It’s called the “Moon Illusion.”  It is not really bigger, our brain just perceives it as bigger.  When the moon is at a low enough altitude, our brain compares the moon to the objects on the horizon and we perceive the moon as being bigger than it actually is.

Don’t believe me?  Next time there is a full moon that looks really big coming up at nightfall, take a paper tube like out of a roll of paper towels or toilet paper or even roll up a piece a paper and tape it.  Just make sure  it will stay a consist size.  Look at the moon through the tube when it’s low for a baseline.  Later, when it’s high in the sky, look at it again through the same tube and it will be the same size.

When the moon is high in the sky, there is nothing for our brain to compare the size to so it appears smaller than when it was near the horizon.  It is simply an optical illusion.

Next time you see that big Harvest Moon coming up, kiss your spouse and say, “That’s amore!” And tell them about the Moon Illusion.  If you really want to score brownie points, make them some nice pasta with a good wine and tell them that your love for them is no illusion and see what happens.  😉

Eye Myth Busters #2 – Pinhole Glasses to Train Your Eyes to Not Need Glasses

15 11 2013

You remember.  1973.  You see the ad in the back of a comic book.  X-ray glasses!  Every young man’s fantasy.  As an adult, you think, “Ugh, some things are better left unseen.”

Some things just seem to be too good to be true, until you waste your money and find out the product doesn’t end up to do what was advertised.  Remember Blue Blocker Sunglasses?  “As Seen on TV!”  They did actually help the contrast by blocking the blue end of the light spectrum but were so cheaply made and the reddish-orange color was not very cosmetically appealing.  They also skew the way colors look.  It made your grass look really green though!

Pinhole glasses.  That one has been around for quite some time too but they have made a resurgence in the last decade.  Lenses that have multiple holes in them that help train your eyes so you don’t need glasses.   Sure….  And I’ve got some swampland I will be willing to sell you…for a bargain price!

Looking through a pinhole will help you see better if you need vision correction, not a medical eye problem.  It works by eliminating all the light rays that are coming into your eye at an angle.  The only light that can enter through the small aperture is coming in perpendicular to your pupil and will land on your retina to see without needing to be bent.  The only problem is….YOU HAVE TO LOOK THROUGH A SMALL HOLE FOR IT TO WORK!

You cannot “train” your eyes or brain to get better vision.  It’s simple physics and anatomy.  Blurry vision either comes from refractive error or a medical problem.  If it’s refractive error, that comes from the shape of one or more parts of the eye not being optimal (nearsightedness, farsightedness, astigmatism) or by the lens of the eye not being able to accommodate or flex any longer (presbyopia).  You cannot affect the shape of eye parts to see better by wearing glasses.  Period.   Technically, you CAN temporarily improve your vision by wearing certain hard contacts (orthokeratology) at night to mold the eye to a certain shape for during the day but I don’t recommend that.

In the end, there is no way to get better vision except to put a lens in front of the eye to help bend light to a sharp focus in your eye or do some kind of surgery (Lasik, cataract, etc.) to change the shape or refractive power.

So the next time you see some kind of ad with some salesman with an Australian accent for Super Specs from Ronco promising to get rid of glasses, just laugh and switch on by.    Maybe save your money for those new fat burner pills that make your lose weight without eating less and exercising!

For Your Eyes Only

8 11 2013

Ever seen the spy type movies where the government agent puts his eye up against a camera and a laser seems to scan across his eye like a grocery store bar code scanner?  It is for real.  They scan the retina to identify people since the retina in everyone’s eyes is unique, like a fingerprint.  No one looks just the same.  Well, we can do the same thing in our office!  Yes, we can identify you if you are a secret agent!   Just kidding.

However, we can identify various eye diseases and tumors or signs of underlying medical disease such as diabetes, high blood pressure, high cholesterol, or blood disorders when they affect the blood vessels in the eye and leak.

When you look into the Optomap instrument, a digital camera system captures an image of the back of your eye with the help of a mirror and two different colored laser lights.  It is painless and is quicker than you can blink your eye.

An Optomap retinal exam provides:
• A scan to confirm a healthy eye or, to detect the  presence of disease.

• An overview or map of the retina, giving your doctor a more detailed view than can be achieved by other means.

• The opportunity for you to view and discuss the optomap images of your eye with your doctor at the time of your exam.

• A permanent record for your medical file, enabling your doctor to make important comparisons if  potential  problems show themselves at a future examination.

This is an example of the difference between looking inside with just a small pupil versus looking at the retina with an Optomap image.  As you can see, it provides a much better overall picture at one time of the state of the retina.  Much like a satelite picture is good for a broad perspective.  Then if something is noted, we can isolate in on a specific area with higher magnification at the microscope.

It does not replace the need for dilation, it only assists in the total examination of the eye to ensure everything is healthy.

The Optomap Retinal Exam is fast, easy, and comfortable.  It does not cost very much and I recommend it highly at every visit for everyone, especially young kids.

Come in for a comprehensive eye exam and have your retina mapped.  It’s our mission, not impossible,  to save your vision!
