Choosing sunglasses: Designer brands or a generic brand to save your retina?


To wear or not to wear designer sunglasses? Are ordinary sunglasses just as good as designer brands in function? What valuable features should one look out for when purchasing a sunglass?

Function
Firstly, the purchaser has to decide the primary function of the sunglass:
1) To look like a celebrity, or
2) To avoid outdoor glare while
a. skiing
b. surfing or fishing or water sports
c. hiking or outdoor, non-water or skiing sports

Durability
My research finds is hard to combine the above two choices. However, some sporty find durability is a feature that must be valuable. The frame must not celebrities have made many functional choices quite desirable! After functionality, I snap easily. The frame material should be able to withstand heat for sure. After all, are not sunglasses supposed to be worn in serious sunlight? I have heard many complaints of sunglasses simply snapping easily in extreme heat. So, I would give the highest value to a frame that can withstand the highest, recorded temperatures in the world. It would be thoughtful if the manufacturer planned ahead for global warming, in case our planet warmed significantly higher during the lifetime of the purchased sunglasses. The lenses have to be scratch resistant. One tends to drop glasses and they do manage to find the only sharp object to fall upon. Also, one tends to clean lenses with material lying around and rarely the chamois supplied by the manufacturer, because either it gets lost or is never conveniently close by. It would be a shame to pay a lot for sunglasses only to find that an innocent cleaning or a perfectly normal “dropping” produced a scratch on the dark lenses. It is quite possible that the damage happens within a week after purchase. That would be an absolute waste. So, durable sunglasses is important to me. Some retailers provide life-time warranty for durability claims. This warranty is worth the purchase price when shopping around. Yes, expensive designer glasses do break and a warranty would replace them for free. If you lose them, however, the warranty does not cover a replacement.

Superior Technology Claims
Personally, I feel this should be the most important feature in a sunglass when the function of the sunglass is eye protection. However, the reason I put this most important feature after durability is because it would be senseless to pay for superior technology mounted on an inferior frame and non-scratch resistant lens.

Designer Brands: Now, lets review the few designer brands that claim superior technology available today and marketed to attract your purchasing power:
1) Water sport athletes favor Costa Del Mar sunglasses. Patented WAVE 580 lens, enhanced color discrimination, sharper contrast, better definition, ultimate UV protection, 100% polarization, glare control – Light above 580 nm is extremely intolerable because of glare. Visual acuity is improved by controlling this glare, making it a preferred choice of some professional water athletes, even in extreme weather conditions. Comes with a life-time warranty from the factory – invaluable!

Costa Del Mar Sunglasses
Costa Del Mar, headquartered in Ormond Beach, Florida, is the leader in polarized eyewear, offering more than 30 styles and 16 lens options.

2) Aviators to extreme sports athletes may prefer a technology that removes the need to squint in harsh sunlight. This feature is provided by Eagle Eyes sunglasses designed by NASA scientists from the discovery that eagles have unique oil droplets that process all harmful radiation to protect the eagles eyes. Visual clarity is achieved by allowing only specifically save wavelengths to enter the eye using their patented Trilenium Gold lens technology. Obviously, a worthy use of citizens tax dollars. Provides clip-ons for those with prescription glasses in some styles, which can be very useful if your prescription changes frequently.
Using their patented Polarized Trilenium Gold Lens Technology, Eagle Eyes lenses make everything vivid and sharper, relaxing your eyes and erasing the need to squint.

3) For Athletes who prefer sunglasses endorsed by high-level ski and surf athletes, Electric sunglasses is the brand. The frames can hopefully withstand the cruelest temperatures because it is made of memory retaining, mold-injected grylamide. The lenses are highest grade polycarbonate blocking out 100% of UV rays.

Electric Sunglasses
Electric Sunglasses lenses have the highest-grade polycarbonate lenses available, blocking one hundred percent of UV rays while filtering out harmful UVA, UVB and UVC rays.

4) For quality materials, style, and value you may want Ray-Ban sunglasses which set the standard for all American sunglasses when it launched the aviator sunglasses in 1937. I was very impressed by its polarized feature. To truly understand the function of a polarized lens, walk into a sunglass store, try on a polarized Ray-Ban and look out of very sunny window. You have to experience the difference to truly understand what polarized is attempting to achieve. Todays improved technology allows for a superior polarized lens material to be sandwiched in the lens during manufacture, allowing for a longer lifespan of this lens.

Ray-Ban-Sunglasses
Ray-Ban Sunglasses were launched in 1937 with their Ray-Ban Aviator Sunglasses brand, setting the standard for American sunglasses.

As for the designer brands which claim style over function, it is an individual’s choice as an expression of their personality.  You have a right to express yourself. Be bold and be yourself.
