Reasonable cost of FDA approved sunglasses
The cost of any product including sunglasses is driven by the open market. The market is driven by trends and popularity. Trends and popularity are driven by celebrities and famous people (past & present). And finally, celebrities and famous people are driven by social and public medias. Like some products there are some sunglasses that never go out of style like the Ray Ban Aviator 3025. Since 1936 Ray Ban Aviator 3025 is still being worn today by current celebrities like past celebrities wore before them, partly out of tradition. So, with that being said, here is my cost analysis.
Cost Analysis
To be more practical you can purchase good quality sunglasses FDA approved under $100. Here is how it often works. Let me choose a Bestseller, Ray-Ban RB2132 New Wayfarer sunglasses. This sunglass style comes in 18 different frame/lens combination colors and only one is under $100. For under $100 your only choice of color is Top Rubber Grey with green lenses and only one size 55/18-145. I would recommend this rectangular shape frame to my warm skin, medium size, narrow head, oval, round, and heart shape heads. This is an excellent value with limited choices. But with this excellent value you miss opportunities in looking and seeing your best with the 17 other color and lens options. Take for example, those who fish and like being on the open waters. I would recommend the Havana (frame color) Blue-Green Polarized lenses. Blue is a recommended lens color for deep sea fishing and green for freshwater fishing. Green will help you see fish easier in fresh water especially with brownish dirt bottoms. The polarized lens will help knock down glare reflecting horizontally off the water. These sunglasses would cost you $200, in addition it comes in two sizes small & medium (according to my measurements). I would recommend these sunglasses to my cool skin, small and medium size, narrow face, oval, round, and heart shapes faces.
