Extra, Extra, See All About It!

7 11 2014

This time of year during fall when the sun is shifting on the horizon it just seems like the glare is worse than normal at sunrise and evenings.  Especially in the flat, treeless plains of the Texas panhandle where you can see forever.  Sunglasses are a necessity when that sun is coming right down the street in your eyes.

In the past, photochromic lenses that change with the light have limited darkening behind the car windshield so most people would have to have a separate pair of sunglasses that stay dark all the time.  That works great but sometimes it is inconvenient for some people when they walk inside and don’t have their clear pair with them or have no place to put their sunglasses once inside.

Transitions Optical has a newer product available now called Transitions XTRactive.  The basic Transitions Signature lenses are better than ever but still need UV to change them.  Windshield glass blocks UV light and so while they are good, they aren’t the very best option if you drive a lot and want to reduce the brightness of light.

Transitions XTRactive lenses however get dark behind the windshield and yet still get almost perfectly clear inside.  The lens tint once you go inside is almost indiscernible.  So if you are one of those that seem to always be switching glasses or end up wearing your sunglasses inside because you forgot the clear pair, this might be a great option for you.

We have demonstration lenses available to see for yourself how dark and how clear they become.  We even guarantee them if you are not happy with their performance and will exchange them for another type.

Come see what they are all about!

Transitions Lenses – Experience It!

2 02 2014

Experience it!  Experience the world.  There are so many beautiful things to see.  Life is too short to miss it.  Many of us are and we don’t even know it.

For example, when we check young school age children, we occasionally come across one that finds out (usually boys) that he can’t distinguish between the reds/brown/green family of colors.  They just don’t know what they are missing.  To them, everyone sees that way.  You don’t know what you don’t know.   

By the way, I hate the term color blind.  It’s not really accurate since most people who have a color vision problem aren’t blind to colors, they just don’t appreciate all of them as distinctly as others.

However, even people with normal color vision don’t always experience the world with all it’s full glory and color.   The glare of the sun, the haze in the atmosphere, the blue light from electronics…all are causing interference to our vision everyday and sometimes we don’t even realize it.

The new Transitions Signature VII adaptive lenses  have just been released and I have to say I’m impressed. (http://www.transitions.com/en-us/products/transitions-signature )  The lenses are a true dark grey and they get darker in warm weather now, which has been a weakness in the past.  They really make the contrast of colors “pop” more.  I cannot see any tint to it indoors and they change extremely fast.  After seeing it in action and learning more about the new lens technology, I am a bigger believer than ever in this lens now.

We are so careful now days about UV damage to our skin that we now know is a cumulative exposure risk.  The earlier in life we are exposed to damaging UV rays and the longer we are exposed the more risk.  It’s important to start protecting your kids early.  Transitions are sunscreen for the eyes!  Why would you not want you and your kid’s eyes  not protected from harmful UV rays at the earliest age?  And kids are more outside than adults!    I recommend them to all children.

Just like shoes or tools, one lens often doesn’t meet all our vision requirements.  I still recommend sunglasses as a secondary pair while driving for maximum lens darkness.

The new Transitions Signature VII lenses come in all types of lens materials and lens types, including bifocals and progressives.  You can even “test drive” the technology with peel off stickers available at our office that can be placed over your clear lenses to simulate the Transitions Signature 7 lens if you are not sure.  We have sample lenses that we can show you as well.

Come by our office and experience them for yourself!   Don’t miss out on the world.  Experience it to the max with the new Transitions Signature VII adaptive lenses.

Snowblind

5 12 2013

 If you live in an area that receives snowfall, you may remember someone in school coming back from a ski trip that didn’t wear sunglasses or goggles on the slopes and ended up with a case of severe snow-blindness or sunburn to their eyes.  Their eyes hurt so bad and were so blurry they couldn’t go back to school for a couple of days.  

We all know how UV light can cause a sunburn to skin.  Well, snow and water are great reflectors of UV light, so that it bounces right up into the face and eyes.    There is more exposure to UV as well at a higher altitude on the mountain.   Without protection, the cornea can develop a “photokeratitis” or corneal inflammation that is extremely painful.  It feels like there are rocks or sand in the eyes.  The cornea becomes covered with lots of micro-blisters that pop open and your eyelid scrapes across those when blinking, causing the foreign body sensation.  Between those and the corneal swelling, the vision can be very blurry.  Depending on various factors, the process of photokeratitis can begin in as quick as 3.5 minutes of UV exposure. (1)   The symptoms are usually delayed, with an average of onset of pain, light sensitivity and tearing after 6-12 hours.

Treatment includes cold, damp compresses or ice packs, non-steroidal and steroid eye drops to reduce the inflammation and pain and possibly antibiotic creams, therapeutic bandage soft contacts or eye patches and oral pain relievers if severe enough.  Typically it will be healed after a few days since the corneal tissue is one of the most fastest growing parts of the body.  Usually, there is no long term damage.  Repeated exposure to UV over your life time can however  lead to early cataracts and possibly macular degeneration.

Prevention is key and very simple.  Wear eye protection in the snow or when on the water!   Polarized sunglasses are ideal to block UV light and improve the vision from the glaring polarized light coming off the snow or water.  There are clear UV blockers in regular eyeglasses too that can block light, much like sunscreen ends up clear on your skin after application.

If you happen to stay too long out on the slopes without eye protection, you CAN come crying to me.   🙂   (But just don’t say I didn’t tell you!)

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!

Why are glasses so expensive?

19 09 2013

From time to time I hear the question, “Why are your glasses so expensive?  I can get them a lot cheaper at Bigmart.”  To which I reply, “The real question is why are their glasses so cheap?”

Let’s think about this.  Why are some glasses more expensive and some so cheap?  It’s like anything else, you get what you pay for.  Whether it is a car, furniture, jewelry, tools or shoes.  Yes, you technically can get a pair of glasses at some places for $37.53.  That should be your first red flag because there is no tax on glasses as a health care device.  So why is there some crazy, arbitrary sounding, odd number like they added tax or something?   I submit it is a marketing ploy.

There is a lot of advertising done by the discount opticals, both in print and on television.  They usually have a large store with several employees also.  The optical equipment that it takes to make eyewear is not cheap as well.  So…just how can they pay for all those expenses with high overhead costs and still make it as a business.  Well, you sell low quality materials and don’t pay employees very much.  I assure you that you don’t get the best trained employees and the best customer service with minimum wage salaries and limited benefits.

Just like other material goods, eyewear can have different levels of quality.  Ever bought a piece of particle board furniture that lasted only a year or less?   A hardwood bookcase that your grandma has could be 75 years old and still going strong.  Materials used to make eyewear frames and optical lenses matters.  A lot!   All metal is not the same.  Iron and aluminum are both metal but have very different strengths and weight.   Frames made of inferior metals bend out of shape and turn green with the oils from your skin.  It’s almost impossible to keep them adjusted well on your nose and ears.  They don’t have good soldering points and break under the littlest of pressure.  The finish on them that is supposed to protect them and keep them shiny can come off very easily as well.

Plastic frames also vary in quality.  Plastic is plastic you might think.  Well the plastic cutting board you might have is a lot harder than your plastic kitchen spatula.  Plastics vary in quality as well.  If you have a cheap plastic frame, it will not stay in adjustment to your face too.  The hinges often loosen in cheap plastic frames and can even pull out of the plastic.  Cheap plastic is very brittle and breaks very easily.

Optical lens materials vary as well.  Plain plastic lenses(CR-39) and polycarbonate are known to have distortion.  Some brands are more optically pure than others but many big opticals are using the cheaper made versions that have inferior quality from places in China to keep down costs.  The optical quality is not good with distortion and waves in them, much like a fun house mirror.  This can cause headaches, eye strain as well as just poorer vision.  The Transitions tint they supposedly sold you, that makes your glasses change darker outside are probably not the actual,  better Transitions brand.  Scratch resistant and no glare lens treatments are often one-sided protection and older, inferior technology that peels off easily.

It also takes time and money to train good opticians.  Part of the eyewear price includes their services in helping you select eyewear, take measurements and for their education and training.  The best opticians are certified by the American Board of Opticianry.  In the course of interviewing opticians from these Bigmart stores and applying myself for a job at one once, it is a fact they employee minimum wage or slightly higher employees with rudimentary training.  How does it feel knowing that someone in the tire shop or the ladies clothing department 10 minutes earlier is now measuring your eyes for glasses?   I don’t know about you but I want someone who is an expert at it.

So how do I know what I’m getting is better quality?

First of all, go to a reputable, independent optometry office.  Someone that is going to be there for you and not gone the next year at a Bigmart or a mall store.  There usually is a reason they are working in places like that.

Secondly, use an optical that has ABO certified opticians.  They at least have taken a 4 hour exam to certify they have more optical knowledge and training.

Next, opticians should be able to explain why they are using certain brands of materials.  Why they will perform better for you.  They should be able to customize eyewear for your specific needs.

Try on an expensive frame that is well made of better material and you will be able to see and feel the difference in a cheaper frame.  It won’t be as flimsy and bendable.  It just feels solid.

Brand name materials that are better quality will often have a card or certificate of authenticity to make sure you are getting a real Transitions or other lenses like Hoya digital progressive lenses with EX3 anti-glare treatment.  Make sure the optician gives you that documentation if you are not sure.  If you are paying for the best brand, you should get that brand.

The best materials will have better warranties that come with the eyewear, not something you pay extra for.  Most optometry offices provide one year warranties on good frames and lenses at no extra charge.

Quality eyewear is not expensive when you realize that compared to other common items like an Iphone or Ipad, that cost as much or more and are really just convenience items, they are helping your eyes function well and see your best with little inconvenience.   You use your eyes everyday, all day.   Why settle for something second-rate?    If you are sacrificing clarity of vision, always needing them fixed or adjusted and making your life aggravated, is that really worth paying for cheap glasses?  You may get “cheaper” glasses but you are not getting the same thing cheaper.  It’s not apples to apples.  You are getting cheaply made, inferior glasses for a low cost.  A Kia is a cheaper car but it is not a Mercedes.  I don’t think you would brag excitedly to someone, “I’m driving a Kia!” but you would with a Mercedes or Cadillac.   Take pride in your eyewear and take pride in knowing your vision and your eyes are going to be at their best with good quality eyewear.  You do get what you pay for.

Snowblind!

5 12 2011

As it snows and blows outside, I often wonder how the early pioneers survived.   They had to be so much tougher than most people living today.  My father and my maternal grandmother still recall even up to the 1950’s,  living in houses in Iowa where the snow blew in through the spaces in the walls.   My dad explained that “if that’s all you know, you don’t realize how much more comfortable you could be with modern conveniences.”  It’s true.  You don’t know what you don’t know.    So with my fancy, Oakley polarized sunwear that protects my eyes and makes me see better with the sun shining on the snow, I also wonder how did the pioneers in the 1800’s or even the Indians not go “snow blind” before sunglasses were made.

Snow blindness is when the ultra-violet (U-V) light from the sun reflects off the snow or ice and causes a phototoxic keratitis (a sunburn to the cornea).  Photokeratitis can be from welding (flashburn) or suntanning with insufficient protection in front of the eyes.   I have treated many a teen age snow skier that didn’t listen to advice and skied even for a brief amount of time without their sunglasses and ended up in severe pain.  It makes the eyes feel like someone poured sand in your eyes!  It hurts!  The eyes will also be red, water and will be intensely light sensitive for 24-48hrs.  More severe burns can actually damage the retina (back of the eye).

While welder’s have had home remedies for years, modern treatment consists of cold packs, non-steroidal anti-inflammatory eye drops, steroid eye drops, and even patching the eyes.  If you end up with a photokeratitis and are in pain, see your eye doctor right away to minimize the damage and help relieve the pain.

Prevention is best and is as easy as using eyewear that blocks the U-V light.  A polarized U-V blocking lens is best as it eliminates glare to see better and blocks the U-V radiation to protect the eyes.  The Eskimos fashioned goggles out of bone or antler that had horizontal slits to block most of the U-V light.  There are many stories of pioneers and settlers that were lost and died or just layed up for days due to snow blindness since they had no eye protection back then.  I guess in a worst case scenario in today’s world, you could make your own Eskimo goggles with duct tape and make a slit over your regular glasses to see through!   (kidding!)

So be prepared when the sun comes out and the snow is covering the ground.  Have a good quality,  polarized, U-V blocking sunglass lens to wear to protect the eyes from the agony of snowblindness.
