But did you know that polarization sunglasses can also help people with certain eye conditions see better both inside and outside?
Photo chromatic polarization sunglasses are perfect for those who suffer from light sensitivity. These lenses, which turn darker when more light is present and lighten again when light is reduced, can help those with eyes that are sensitive to large amounts of light. They are perfect for people whose lighting environment changes often, such as going from outside to inside, and allow the eye to be protected from harsh light. Those who have just had cataract surgery are also good candidates for these types of sunglasses.
For those who suffer from farsightedness, polarization sunglasses can help improve their ability to read or see object that are close up. These lenses also reduce eye strain and squinting thanks to their ability to reduce large amounts of glare.

This is sure to take a stroke or two off your game.
Polarized sunglasses have long been used by boaters and fishermen for their amazing ability to reduce the sun's glare reflected off the water's surface. The benefits of these lenses are quickly catching on as more and more people are using them for all their outdoor sunglass needs.
When light is reflected off a smooth surface, such as water or a road, the light is usually polarized in a horizontal manner. Polarized sunglasses combat this glare by blocking light with their vertically polarized filters. This filter reducing the amount of light reflected into the eye and improves visibility and clarity of objects.
Polarized sunglasses are perfect for most outdoor activity such as skiing, golfing, biking or even jogging. Anytime that you need to block glare a pair of polarized lenses can improve your outdoor sight. You can also get polarized lenses in various tints that will further improve your visibility depending on the lighting conditions.
EyeSave Tip: Wearing sunglasses is a great way to increase visibility while driving on sunny days and protecting your eyes from harmful UV rays. However, did you know that some lenses are better for minimizing glare than others?
There's a true science behind polarized lenses. When light is reflected off a smooth surface like a flat road or water, it becomes polarized horizontally. The polarized light can cause eyestrain and fatigue. So polarized lenses, such that are used in Spy Optics sunglasses, use a filter that blocks out that reflective light and allow the desired amount of light to pass through.
Polarized lenses are great for out-of-doors, but they can also be used indoors by those sensitive to light, including patients who have just had cataract surgery or have had their eyes dilated by the optometrist.
Polarized lenses have been gaining in popularity due to their ability to dramatically reduce glare from smooth surfaces such as water and roads. Though they are perfect for many outdoor environments there are some instances when using polarized sunglasses may not benefit the wearer.
There is much debate about whether or not using polarized lenses during downhill skiing is a safe practice. Some experts say these lenses reduce the glare caused by the sun's rays reflecting off the snow. Others warn that using polarized lenses may reduce a skier's ability to distinguish between regular snow and more dangerous conditions such as icy patches or moguls.
There are also reports that using polarized lenses to view any type of LCD screen, such as the ones in the dashboard of some vehicles, could be problematic. Apparently, when an LCD screen is viewed at a certain angle through polarized lenses the screens can become invisible. Other instances of improper screen viewing can be at ATM (banking) machines or for those who wear polarized lenses indoors and work at a computer with an LCD screen.
When it comes to sunglasses, one size and style does not fit all. You need to consider the wearer and their needs in order to find the best discount polarized sunglasses to suit them. Here is a guideline for choosing sunglasses that will be a hit with the whole family.
Men traditionally need sunglasses that are both stylish and rugged. Look for men's discount polarized sunglasses made of sturdy materials and that suit the size and shape of his face. Sunglasses that are intended for wear during sports should be created from lightweight and flexible materials to minimize damage from contact. You'll also need to be sure the tint of the lens will aid in visibility for the lighting conditions and environment he'll be in. If the sunglasses are going to be worn for more casual purposes then metal frames are a great choice as they're both stylish and flattering.
Women tend to choose their sunglasses with style in mind. Checking out the current trends can help you choose a great pair of discount polarized sunglasses. Just don't be a slave to fashion at the expense of your features. Since you'll also want your sunglasses to protect as well as flatter, be sure the lenses block 100% of harmful UV rays. For women who love sports there are sunglasses that blend style and function such as the Bolle Kicker sunglasses with wrap around lenses. These look great and provide excellent eye protection while blocking out excess sunlight.
Kid's sunglasses are becoming more and more popular as parents realize the harm that UV rays can cause on everyone's eyes. Children's discount polarized sunglasses come in a range of sizes from infant sunglasses to larger and sportier styles for those active teenagers. Kid's sunglasses should be very durable to withstand a great deal of abuse. Scratch resistant lenses and flexible hinges will help sunglasses deal with what kids dish out.
Spy Optics sunglasses are the leader in technologically advanced sunglasses. In fact, their Scoop technology is so efficient that it has five US patents attached to it. The Scoop technology of the Spy Optics sunglasses virtually eliminates pesky fogging of your lenses by forcing air through scoop vents when you move forward. This movement is done through a Venturi effect in which warm humid air is drawn into the scoops and out behind the sunglasses' lenses.
If you love the customization of interchangeable lenses, check out Spy Optics' Commando Kits.

Kit one comes with both clear and orange tinted ARC lenses, which suitable for low lighting conditions such as overcast or snowy days. Kit two provides a pair of yellow and cyan ARC lenses. Use the yellow lenses for low lighting conditions and choose the cyan lenses for blocking out the sun's rays on bright days without having colors faded out.
All Spy Optics sunglasses come with a one year warranty. Do be aware though that the warranty does not cover normal lens scratching from wear and tear. You will need your original receipt with the purchase date on it. If you do not have your receipt Spy Optics will still replace your lenses for a nominal fee.
Choosing the right pair of designer polarized sunglasses takes some forethought. The first thing you should consider is what the primary use of your sunglasses will be. Are they just to keep your eyes protected while looking fashionable? Or are you going to be participating in a specific sport and need greater outdoor visibility? When you know exactly how you're going to use your sunglasses you can make a more informed decision as to what your exact needs are.
If you plan to be outside for extended periods of time in bright sunlight you may want to opt for polarized sunglasses with a gray tint that maximizes your overall visibility of objects. Lightweight and comfortable frames are also a necessity if you're going to be wearing your designer polarized sunglasses for any length of time.
If you plan on using your designer polarized sunglasses for a specific sport try seeking out sunglasses made specifically for that sport. Tennis players can easily keep their eye on the ball by choosing polarized lenses that mute all colors except the color yellow, making the tennis ball literally pop out of the background. By the same token, golfers can choose lenses that are tinted to enhance the contrast of the green color spectrum and provide greater contrast of objects against the golf greens. A white ball and beige sand trap will be much easier to spot with lenses like these.
A new type of polarized lenses now reduces glare, protects against UV rays of the sun, and blocks blue light, too. SunRx polarized melanin lenses are a new innovation that come in brown tints, and block blue light, which some doctors think can add to the development of age-related macular degeneration, which can result in blindness. These lenses should become more readily available in many polarized sunglasses soon.
Light reflected from surfaces like a flat road or smooth water is generally horizontally polarized. This horizontally polarized light is blocked by the vertically oriented polarizers in the lenses. The result is a reduction in annoying and sometimes dangerous glare. But what about snowcover? Some believe that the glare that results when sun reflects off snow can be reduced by polarized lenses. Others say that the lenses are not good for snow sports because they may not provide the contrast the eye needs to distinguish patches of ice or other snow formations that could be dangerous.
MAX-LT is a new sun lens that provides 100% polarization with 40% light transmission. This lets much more light through than other polarized lenses. MAX-LT polarized lenses are ideal for low light environments or if your eyes are beginning to age. MAX-LT lenses are available in several sunglass frames made by Live Eyewear, including the sporty styles for active sunglass wearers. They're even designed to be worn over your prescription eyeglasses.
Polarized sunglasses lenses are invaluable in high-glare situations, such as driving, boating, golfing, surfing, and fishing. The polarized lenses help reduce glare, which can be a real problem in water sports and many other outdoor activities. They also come in transitional lenses, which will darken outside and lighten inside. Choose polarized lenses if you are outside in high-glare situations a lot.
Polarizing a lens is the process of laminating on or casting in a polarizing film to a lens. Costa del Mar sunglasses use the cast-in process. The polarization film consists of polyvinyl alcohol molecules which run in horizontal parallel chains. These chains filter out light that bounces off horizontal reflective surfaces such as water, the highway, or the moisture in the air around you. Reflected light is 7 to 10 times brighter than ambient light and is commonly referred to as "glare."
Some polarized lenses can block the reflected light of LCDs, too. These are the lights in many dashboards, bank automated tellers, and other electronic devices. So, if you use a PDA, laptop, or have an electronic dashboard, you may want to check and make sure that the polarizing lenses you choose will not block out LCD light, too.
For those who use sunglasses to drive or who wear them indoors, polarized lenses may not be the best option. Studies have been done concerning the effectiveness of the lenses inside your vehicle as well as outside. The polarized lenses, it seems, may react adversely with liquid crystal displays (LCDs) found on the dashboards of some cars or in other places such as the digital screens on ATM machines. When viewed through polarized lenses from a certain angle, LCDs can become virtually invisible.
If you wear progressive lenses -- multifocal lenses whose corrective powers change progressively throughout the lens -- polarized progressive lenses are perfect choice. Especially if you enjoy outdoor sports. They offer protection and the ability to discern objects at a distance as well as up close. Also, polarized photochromic lenses change from dark outside to light inside. These are a great choice for those who move from indoors to outdoors often, such as gardeners and construction workers.
After being outdoors in the sun without proper eye protection, glare can cause eyestrain and fatigue. Ver quickly, it also reduces contrast and visual acuity. Polarized lenses are designed to reduce glare by selectively absorbing light waves. Ray-Ban sunglasses offer lenses that cut out the white glare on the water, road, and everywhere else. Hot styles include the polarized Predator 1, the Daddy-O Oval Wrap, and the Daddy-O Square Wrap.
