Don’t Forget UV Protection this Winter

Most people think of sunglasses as summer gear, but in some ways it’s even more important to wear sunglasses in winter conditions than in the warm summer months.

Thanks to public awareness campaigns about the risks of skin cancer, more people are aware that UV rays and intense sunlight are bad for our skin. Sunblock, clothing, and shade are regularly used to protect us. Do you know that UV rays are damaging to our eyes, too?

Prolonged UV exposure raises risks for:
• Cataracts
• Macular Degeneration
• Pingueculae
• Pterygia
• Photokeratitis

In the warmer months, we think about protection from the sun because we expose so much skin and can experience sunburns when we’re not covered. In the winter, however, people are colder, and bundled up, so they don’t think of the sun as a risk. This is a problem because snow can reflect 80% of UV rays! That means you’re experiencing normal sunlight from being outside, and harsh glares from white surfaces.

The fatiguing effects of winter glares become apparent usually when doing outdoor activities like skiing, snowboarding, or sledding, but driving in bright wintry conditions can also be damaging and dangerous. It’s important to be protected year-round!

When looking for appropriate winter sunwear, remember:

• Good sunglasses offer UV protection, so always be sure to check that they block 100% UVA/UVB rays.
• Larger glasses are in style, which is great because the bigger lens protects more of your eyes and the skin around your eyes from UV damage. Look for a large lens and wraparound style.
• Don’t worry about the color or darkness of the lens. Those things can vary while still providing adequate UV protection. Check the label for that information, or speak to an optician.
• Remember, polarization is for more than fishermen! Especially in the winter months when ice and snow can cause harsh glares, polarization can be a big help.
• Specialty eyewear exists for all of your favorite winter sports. Be sure your eyes are protected from the sun and safe during sports.

The Pros of Progressive Lenses

Multifocal lenses have made everyday life much easier for people over forty. Bifocals were invented sometime in the 1700s, but trifocals and eventually progressive lenses were later created to give wearers even more functionality. The options are great, but making the choice can be difficult!

If you need multifocal lenses to provide you more than one power, progressive lenses may be a perfect fit. They have many benefits and can work in almost any setting.

Here are some things to consider for your progressive lenses.

How Progressive Lenses Work
Progressive lenses are called “progressive” because they gradually change from one magnification to a stronger one at the bottom of the lens. They progress from a distance vision prescription to an intermediate and then a near-field one. This means that the wearer can look up to the horizon in the upper portion of the lens and see distances clearly, use the middle of the lens to look around their intermediate space, and view reading materials and close up objects through the bottom of the lens. This use of progressive lenses becomes second nature after some adjustment.

Are Progressive Lenses Better than Bifocals?
Many people prefer progressive lenses over bifocals for two reasons. First, bifocals only have two prescription powers. They usually address a farther distance and a close-up reading view. Either an intermediate distance or a certain distance will not be completely clear. Second, some people are distracted by the “image jump” that they see when looking through bifocals. This is caused by the abrupt line where the inset meets the rest of the lens. Some people love bifocals and see no added benefits from progressive lenses, but most people like the versatility of progressive lenses.

Additional Benefits of Modern Progressive Lenses
Multifocal lenses that are not progressive sometimes don’t fit well within a certain frame size. Because lenses have to be cut to fit the frame, the reading portion can end up too big or too small compared to the lens size. Short corridor progressive lenses address this by scaling the reading zones into a more compact area. This means wearers still have their pick of frames and eyeglass shapes.

In addition, specialty progressive eyewear exists to meet certain needs. Computer eyewear can be a great option for people who work at a desktop setting. These lenses do not need the addition of a distance vision section. This means that they allow more room for a close distance focus, and then the rest of the lens is created for the intermediate field. With a computer screen sitting at arm’s length, reading materials up close, and walls at an intermediate distance, these lenses help maximize the eyewear for indoor occupational settings.

Nobody will notice! Some people believe there is a stigma with bifocals because they perceive them as glasses only for senior citizens. Many people even put off getting multifocal lenses because they don’t want to admit that they need them. Progressive lenses help this issue for some people because there is not a visible line like with bifocals. It is unusual for someone to notice that the wearer has progressive lenses unlike the ability to see bifocal lines.

If you have any questions about how progressive lenses can help your eyes see as clearly and comfortably as possible, speak with an optician. There are many options and we can help you narrow down the possibilities so you can make an informed decision.

How to Choose Your Eyeglass Lenses

Eyeglass lens options have grown incredibly in the last several decades. Whereas early eyeglass lenses were made from glass, advancements in lens materials have made them safer, thinner, lighter, and featuring benefits that early inventors never could have imagined!

Glass lenses revolutionized so many aspects of life for people of that time. Glass can provide crisp, clear views, but it is heavy and breakable. It was not uncommon for lenses to break on impact, which could cause someone to lose sight or lose the eye entirely. For that reason, glass is rarely used for eyeglasses today.

In the 1940s, plastic lenses were introduced. Armorlite Lens Company created a lightweight plastic lens made of plastic polymer. It was light, weighing about half as much as a glass lens, and was inexpensive. These plastic lenses were a hit, and are still a common option for eyeglasses today.

Polycarbonate lenses were introduced in the 1970s. Polycarbonate is a highly durable polymer that is impact-resistant, but can scratch. For this reason, the lenses are recommended for children and used in most eyeglasses, but have the addition of a hard coating to deliver greater scratch resistance.

High-index lenses are another lens option that many people aren’t aware of when they begin shopping for eyeglasses. High-index plastic materials make lenses thinner and lighter for people who have a strong prescription. Instead of thick lenses that used to give people fewer options for lenses and make their eyes look distorted from the front, high-index lenses can pack a stronger prescription into a thinner space. This opens more frame options and takes the weight off of your glasses if you have a high prescription!

In addition to lens materials, there are a number of other features that you can add to your lenses for various functionality. For instance, anti-reflective or non-glare treatments are one of the most common upgrades. Often they give added scratch-resistance as well as cutting glares and giving a clearer view of your eyes from the front. Tints are another option you can add to your lenses. For sunglasses, wearers might choose around an 85% tint, but lighter options exist, too. Many lenses can be tinted gray, brown, or yellow. Fashion tints come in rose, blue, green, or even more possibilities. Polarization is a great addition for sunglass lenses, too, because it filters the bright glares that can be uncomfortable, even with sunglass tints.

If you have any questions about the best lenses for your eyes, speak with an optician. They are trained in eyecare products and can assist you with these choices, as well as helping you pick frames that look great on you!

The Advantages of Multiple Pairs of Eyewear

Most people pick either one pair of glasses or one set of contacts, but often find situations where they wish they had an alternative option to their main eyewear. After all, why dress your face in the same outfit every day? Just like having a few pairs of shoes for different uses, or a special purse for evenings out, having multiple pairs of eyewear can be very fun and superbly functional.

There are many reasons why owning multiple pairs of eyeglasses is beneficial. Clumsy or not, you never know what could happen that would cause you to break or lose a pair. Unlike ripping a pair of pants or losing a shoelace, not being unable to see is quite a problem! Although some eye care providers may be able to create glasses in a very short amount of time, you don’t want to be stuck either unable to see, or in an old prescription that will hurt your eyes while you wait for your new eyewear to be created.

Maybe you know in advance that you’ll need a different type of eyewear for a specific activity and want to get fit for your specialty eyewear. Eyeglass wearers need at least one pair of regular glasses, but many also have a backup pair of glasses and may opt for a pair of sunglasses, too. Contacts tend to be the go-to for sporting enthusiasts who need varied functionality for their sport, but there are also prescription options for eyewear used in watersports, winter sports, driving, outdoors, and other activities.

Other specialty types of glasses that you may need are computer glasses or specialty eyewear for work or hobbies. Those that work long hours on a computer could benefit from investing in a pair of computer glasses. These glasses aid in preventing eyestrain, as they are designed specifically for the distance at which you view a computer monitor. They can cut down on glare and blue light, too. There are many options available for safety prescription glasses for work, and your employer may cover them if you need them for your job.

Occupational lenses can be helpful for those who wear bifocals because holding your reading material out far away from your face is not exactly practical nor comfortable. For those whose hobbies include close up work, reading glasses may be helpful for magnification.

Of course, the fashion-forward will also enjoy having multiple pairs of glasses to go with different looks. It is tempting to pick up a very colorful pair of funky frames to give yourself a signature look, but you may wonder if the bold look would feel awkward in other settings, like a serious family function or job interview. If you get more than one pair, you can be more creative with one of the frames and a little more conservative with the second pair. Unless you have a certain kind of prescription, the option of contacts is also great. They’re very practical and versatile. Some contact lenses even offer color-changing ability to give your eyes a totally new look.

Just like the way different accessories make you feel fancy, professional, or casual, glasses and contacts can do the same. Check your vision benefits to see what coverage is offered for additional eyewear, or ask your eye care professional about price breaks on ordering multiple glasses and contact lenses.

Golfing, Fishing, Winter Sports, and More

Just as sports officials are becoming more concerned with overall physical safety for athletes, more people are wearing specialized eyewear to protect their eyes and give them protection and sharp vision while performing their sport. Specialty eyewear options are available and tailored to just about every sport. All you have to do is know your sporting needs and talk to an eye care professional to discuss your options. It’s nice to know what to expect and what you can get other than just wearing contact lenses.

Here are some of the most common options and things to consider for glasses, goggles, or other specialty eyewear with unique capabilities to increase your sporting performance.

Darkened/tinted or photochromic lenses. Is your sport outdoors? Protection from bright sunlight and UV rays is crucial! Watersports and winter sports involve glares coming up from the snow or water. The bright light is damaging to your eyes and very uncomfortable if you’re not protected. Certain color tints can also help make sports glasses more functional. Golf glasses, for example, often use a copper or amber color that improves the contrast of grass and sky so you can read the course better. Make sure that you invest in glasses that will fit your outdoor setting.

Fitting with other gear. Eyewear for activities like motorsports, cycling, or football will need to fit with headgear. Be sure to test your eyewear with your uniform or additional gear, and talk to your eye care professional about the other items you’ll be wearing along with your eyewear.

Durability. In sports like racquetball, or really any sport with objects that are swung or flung around, you face the risk of getting hit and injuring your eyes if they’re not protected. This also means that your glasses or goggles are likely to take a beating while protecting your eyes. Scratch-resistance and high-impact polycarbonate materials are often used in sports eyewear to be sure that they will have a long life and will be able to shield your eyes from harm.

Considerations for contact lenses. Those who wear contact lenses and will be doing their sport in the elements can benefit greatly from glasses that wrap around the face. Protection from wind and debris will ensure that no irritants enter the eye and affect your contact lenses.

Protection from other substances. Watersports may come to mind when you think of goggles that protect your eyes from liquid, but there are other sports like paintball that could greatly damage the eyes if not protected. Specialty masks with breathable vents that allow air in will be sure to keep paint out. Goggles for watersports have similar features to keep water out of your eyes so you can see clearly under the water or above.

Polarized lenses. Probably the most important aspect of eyewear for fishing is polarization. Polarized lenses make it possible to see under the surface of the water because the lenses are specially made to cut down refracted light. Once the sunlight bouncing off the water is minimized, it’s far easier to see into the water and read important fishing features like vegetation, depth, underwater landscape, and even fish! Other water and winter sports can benefit from polarization as well to prevent the eyes from glaring sunlight.

Make sure that you’re prepared for your sport with protective gear and the right eyewear to keep your eyes on the prize. See an eye care professional to give your eyes a sporting chance!

Photochromic Lenses

Lenses that darken automatically when exposed to various levels of light are called photochromic or light-adaptive lenses. This technology was discovered in the 1960s, but it didn’t really catch on until the 1990s. The convenience of photochromic lenses is huge: they’re basically like getting two complete pairs of glasses—regular glasses and sunglasses—in one!

How the technology works is pretty cool. In glass photochromic lenses, silver compounds are embedded into the lens material. When exposed to varying levels of sunlight, the compounds go through a chemical change that increases their size, allowing them to block out more light. Once the bright sunlight subsides, the molecules return to their normal size. Plastic light-adaptive lenses use similar photochromic molecules to create the darkening effect. The reaction that causes the material to darken as it absorbs varying levels of light is completely reversible which is why the lenses go back to clear or only slightly tinted when the wearer is out of bright sunlight.

The only issue you may encounter with light-adaptive lenses is that the photochromic reaction depends to some extent on temperature. In very hot weather, they may not darken all the way. When you first step into the sunlight, the darkening effect happens in about a minute. Over the next several minutes, they may darken just a little more, until achieving their final darkness after about 15 minutes (which depends on the brand and material of lenses). The first reaction will be drastic and give you more than enough light protection to continue into the sun with your vision protected.

If the final darkness of regular light-adaptive lenses isn’t dark enough for what you need, photochromic sunglasses can help. Their darkness when not in the sunlight is still darker than normal glasses. For that reason, most people don’t use these as their only pair of glasses because they won’t see as well indoors. They are a great option for people like drivers, for example, who spend a large part of their time shielding their eyes from sunlight and can wear their backup glasses in low-light settings. The other reason they’re good for drivers is that most windshields block out the UV light that causes the darkening reaction. With a UV-blocking windshield, bright light coming through your windshield will not cause your lenses to darken, leaving you squinting and straining.

There are some other interesting uses of photochromic technology. One medical application involves tinting for certain shades of red. These lenses can be used for various eye conditions including macular degeneration. Of course, there are further recreational uses of adapting tints, too. Red and green shades are used to make a fashion statement, but yellow and amber tints can be used in hunting and sporting glasses to help increase contrast, especially when it is cloudy. Tints can be applied and used in adaptive lenses in just about any color. Want to see the world through rose-colored glasses? It’s possible!

Talk to your eye care professional to test a pair of light-adaptive lenses and see how they’ll help make your everyday life a little easier.

Polarized Sunglasses

Squinting into the sun and focusing in bright light is very hard on your eyes. Eye care professionals stress the importance of sunglasses and shading your eyes to protect your vision, but many people aren’t aware of the benefits that come from polarized sunglasses. They’re not just for fishermen to see into the water!

When you’re not on the dock or deck of your boat, you will continue to see the benefits of polarization. Polarized lenses can help cut glares off of surfaces like the road in front of you or the hood of your vehicle. Even bright light outdoors or through windows can be mellowed with polarized lenses.

The reason that polarized lenses work is that they cut out certain waves of light. Normal light tends to go in all directions, but light that bounces off of a surface tends to “polarize” and align itself horizontally. So sunlight beating down on the water doesn’t appear as ambient light once it bounces off the water, because it hits that reflective surface and bounces up, glaring into your eyes. Polarized lenses are specially made with a vertical polarization so that they cut out that intense reflected light and let you see more of the natural light you’d see if there was no glare. Pretty cool, right? You can even experiment with glasses to see if they’re polarized by holding them out and rotating the lens to see if the glare lessens or not.

Some people may notice instances where polarized lenses are not helpful, however. Cell phone screens, LCD and GPS displays can be more difficult to read. In some cases, much brighter light is something you need to see, like in downhill skiing. A bright patch alerts the skier to ice, and polarization would make it harder to see. But most everyday skiers and snowboarders would like to ease the bright light reflecting off of the snow if they’re not in icy conditions. Other than a few rare occasions, polarized lenses can do a lot to improve your vision for many applications. Ask your eye care professional for help deciding if polarization is right for your eyewear.
