Sunglasses are a fairly common commodity, effective against the glare of the great outdoors and a great way to make a fashion statement. But with so many kinds of sunglasses, it can be difficult to choose the right pair for you. And while many factors such as size and shape play a key role in this important decision, most people are starting to realize that polarized sunglasses are the best option, giving you the best value and protection for your money.
Polarization is a pretty basic term, referring to a reduction in glare reflected off shiny surfaces such as water, and it’s this technology that has been making the rounds in the field of eye wear for a while now. Sunlight is a fairly dynamic element, easily reflected, refracted and bounced off of varying numbers of surfaces, intensity varying accordingly; the glare that results from these actions of the sun will sometimes do more than simply create discomfort; they are capable of causing lasting visual injuries. And it’s with such a purpose in mind that polarization technology is applied to eye wear, making use of a laminated filter that will accept vertically oriented light but reject horizontally oriented rays.
Polarized lenses, a necessity or not? This is hardly a question among today’s crowds because despite the fact that polarized shade were used first by fishermen, because of anti-glare properties allowing for better vision on the water, these specialized items have become fairly popular, mostly because of an increase in awareness of the dangers of sun rays and glare. Be it when driving or for sports, the benefits that polarized sunglasses bring to the table are obvious. Most people are realizing that the comfort and protection afforded by polarized shades are worth the investment. Polarized sunglasses are essential in reducing eyestrain during everyday activities in the sun, will improve color perception, and combat glare and irritating reflections.
Not that polarized glasses are without any faults. Some of them have a weakness because they are most effective with the sun at 37 degrees and less effective as it dips lower with the wear of the day. Authenticity is also a massive problem; just because the sticker says polarized, doesn’t mean that pair of sunglasses is polarized. Fortunately the test for determining whether a pair of glasses is polarized is fairly simply: look at the glare in a portion of water, rotating your glasses at 90 degrees and waiting to see if you notice any change in intensity. If you do, means that your pair isn’t polarized. Finally, polarized shades aren’t great for viewing LCD screens such as on phones and computers.
For almost all your outdoor activities, polarized sunglasses can mean the difference between an awesome day and one filled with glare and damaging UV rays. Grab a pair from Pugs and you'll see clearly no matter where you are!
