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!)

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!

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.
