Be careful of wraparound Rx sunglasses

In order to achieve a maximum degree of eye coverage, sunwear manufacturers typically take a wraparound lens or frame design. In this case, the lenses will be made with extreme curves, especially at the edge. This is really a favorable design because related users can protect their eyes as much as possible. Each pair of these quality sunglasses can shield nearly the whole lens socket from all angles. Today, this wraparound design using extremely curved lenses are taken by almost all notable sunwear brands like Native, Ray Ban, Smith, Bolle and Oakley, just to name a few. What’s more, some people may have heard of wraparound Rx sunglasses. This term refers to wraparound sunglasses that have specific prescriptions for vision correction. From another perspective, most people would suppose that they are only the natural and typical form of prescription sunglasses. This is only partially true. Customers who are interested in these products should take additional consideration.

It is true that there is an increasingly number of customers who appreciate greatly the benefits brought by prescription sunglasses or tinted eyeglasses. UV protection and vision correction are combined within a single eyewear. For folks regularly participating in outdoor activities with poor eyesight, it is hard to point out that which of the above functions provided by Rx sunwear is more important. UV protective lenses are quite essential to fight against hazardous ultraviolet rays. In this consideration, a wraparound lens design discussed before should be the first choice. However, the problem is that this wraparound design involves inevitably extreme lens curves, which in turn typically distort the wearer’s vision. With this explanation, it is understandable that some people consider wraparound Rx sunglasses as a product of dilemma.

The availability of these sunglasses is quite limited because of this confliction between the wraparound design and corrective vision distortion. The currently situation in the market of wraparound Rx sunglasses is that only a few manufacturers provide these products yet with less extreme curves. What does this mean? When certain lens powers should be successfully fitted into sunwear lenses, it is inevitable to compromise in different degrees the wraparound curves. Moreover, only a limited prescription range has been typically available.
