It should specifically mention that in the product description. You should also be careful to avoid any stores that don't offer a satisfaction guarantee or a return policy. Below are some tips to help you find the right pair of polarized sunglasses at an affordable price along with some background information and details about their benefits and production.


What exactly are polarized sunglasses?
Polarized sunglasses are produced with a filter that mostly eliminates glare. Glare results from light being reflected off certain surfaces such as roads, water, and snow. The light that reflects from these surfaces is polarized horizontally usually, meaning that it typically travels more horizontally than in other directions.


Polarized lenses block this horizontal light and eliminate the intensity of the reflected light, and thus glare is significantly reduced. Polarized lenses are excellent for drivers, fishermen, those who work in the snow, and anyone else who needs to eliminate glare from their vision for safety or convenience. Polarized sunglasses come in a wide range of different frame styles and lens thicknesses depending on the need of the wearer, and there are many vision benefits to wearing them.


Glare is a hazard to your eye health
The glare that can result from reflecting surfaces is a significant vision hazard. Glare from reflected sunlight can harm the eyes due to a vision condition called photokeratitis or snow blindness.


Snow can reflect up to 80% of the sun's light rays, with nearly the same effect as looking directly at the sun. It also reflects UV rays, and the result is that the cornea gets a sunburn just as the skin can become sunburned. The thin surface of the cornea is affected as well as the cell layer that covers the inside of the eyelids and the white of the eyes. Not only can glare from snow cause it, but also viewing a solar eclipse without eye protection, using a tanning bed without eye protection, and the glare from arc welding.


Although most people recover from this condition, it can have many symptoms such as redness, pain, swelling, tearing, blurry vision, sensitivity to light, halos in vision, headaches, eyelid twitching, a gritty sensation, and in severe cases temporary vision loss. Symptoms normally go away within a few days; however, they often require a visit to the eye doctor. Color changes can also occur in the vision, and the longer a person is exposed to glare or UV rays, the more severe the symptoms will be.


That's why it is essential to wear the proper polarized sunglasses when you know that you may be exposed to UV light. Most types of UV glare can be negated with the proper polarized sunglasses which also must have UVA/UVB protection. However, it should be noted that viewing a solar eclipse can only be safely performed with special eclipse glasses, not just regular polarized sunglasses.


It's also important to note that long term exposure to UV light is associated with several eye health problems including macular degeneration and cataracts. Exposure to UV light results in retinal damage that accumulates over time, and there are three types of damage that can occur: photochemical, thermal and structural. The type of damage that occurs depends on the length of exposure to the light and the wavelength.


Bright lights such as the sun or its reflection result in the worsening of macular degeneration for those who have already been diagnosed with it. It is therefore crucial that any polarized sunglasses also fully protect against UVA/UVB light which should include protection against the more harmful blue rays of the spectrum. Those who often work or play in the sun should take extra precautions against UV light and glare and be sure to wear the appropriate polarized sunglasses with full UV protection to keep their eyes healthy as they age.


Benefits of polarized sunglasses
The main benefit of polarized sunglasses is the fact that they can protect your eyes from the harmful effects of glare as previously mentioned. Being exposed to glare over a long period can have significant effects on your vision as you get older, so it is important to protect your eyes properly as much as possible anytime that you may be exposed to glare.


Polarized sunglasses also improve your vision in many ways and can make a wide range of different activities safer. If you are driving and are exposed to glare it can significantly affect your vision and increase the chance for an accident. Wearing polarized sunglasses eliminates this driving hazard and makes it easier to drive on a sunny day. Fisherman can also benefit from wearing polarized sunglasses as it can block the glare from the water and help them see it much more clearly. They can even reduce the reflections that come from the sky and clouds, and thus the water or ocean looks significantly more clear. Regular sunglasses don't block light from the water and can often make it difficult to fish even though they reduce the intensity of sunlight.


Golfers also often wear them to reduce glare from pools, lakes or ponds when they are golfing or from the sun reflecting off other surfaces. Polarized sunglasses can be very useful for a wide range of different sports as well as improved safety for boating or driving. Their main use is to lower the health risks of both short and long term UV exposure from reflected light and they are effective at doing so. assuming that the glasses have the proper UV protection which is necessary as a separate addition to the lenses.


Do polarized glasses offer UV protection?
Polarized glasses do not necessarily offer UV protection; it is up to the buyer to ensure that any glasses they purchase have full UV protection included with them. Product descriptions should detail the exact type of UV protection that is included, and it is not sufficient just to have UVA protection; the glasses should also protect against UVB light.


Shoppers must take the time to review each pair of glasses that they plan on purchasing, because polarized sunglasses that do not have the proper UV protection are a major hazard to wear and are just as bad as viewing sun glare without any eye protection at all. Many retailers will see these sunglasses, sometimes unknowingly, but Classic Specs and similar companies only sells sunglasses with full UVA/UVB protection and will notate that directly on each product description for customers.


Disadvantages of polarized sunglasses
Polarized sunglasses do come with a few disadvantages that buyers should be aware of. They are not necessarily a good choice for pilots or anyone else who needs to read LCD screens, as they can distort the screens and make them difficult to view. Downhill skiers may also be better off not using them because they can reduce light reflections off icy patches which the skiers need to be able to see to avoid them.


Polarized sunglasses can reduce the visibility of any LCD display including at a gas station, at teller machines, computers, or anything else that utilizes this type of display, so they will need to be taken off to view this type of display. Boaters may also have difficulties viewing instruments on their boats when wearing them. Some of the devices have been changed to be viewable even with polarized glasses on, but this varies on a case by case basis depending on the manufacturer.
