Rx Wrap SunglassesThe Rx wrap sunglasses have lenses that are made to fit a prescription, especially for people who have near sightedness and far sightedness. These glares are not your regular, off the rack stuff. You can get only get your hands at a pair if you get them made to order. Most of the Rx wrap sunglasses are lightweight, adjustable, and have rimless designs that protect the eyes from wind, dust and glare. These shades enhance your visual acuity with high-contrast colors that enhance your perception. With a higher than normal base curve of 8-12, these sunglasses have a curvature that fits around person's face close to the head. There are a limited variety of colors and sizes in the Rx segments as compared to the others. The prices of these sunglasses starts at 65$ up whereas a non-Rx pair of unbranded sunglasses will cost you no more than 18$. There is a marked difference in price for a pair of prescription glasses because of the following reasons that influence price: 1. The higher the power or astigmatism (disturbance or variation in the shape of your cornea) the more expensive the lenses become. 2. The material used for the lens can create big changes in prices. You pay a different price for prescription sunglasses that use glass, plastic or polycarbonate. 3. If you want a high index lens, which is much slimmer in width, especially for those with a high power since regular lenses can be quite thick in this case. Prescription sunglasses can be easily bought over the Internet, though you need to have a valid prescription for the same. Prices vary with different merchants, but with little overheads or selling costs, most online retailers offer store discounts, manufacturer’s rebates etc. Do your groundwork before you invest in a pair since you can’t afford to make a mistake with the Rx factor. |
