Burberry progressive sunglasses give you all the benefits of shaded bifocals without the annoying "bifocal line" that separates the reading lens from the standard lens. It's easy to pick a pair of bifocal sunglasses out of a crowd; simply look for the line. Progressive sunglasses, on the other hand, are a whole new breed of prescription sunglasses. Using innovative optics technology, progressive lenses work the same way as bifocals but don't have the tell-tale bifocal line. You can still read at short distances by looking through the bottom part of the glasses or observe things going on around you with the rest of the lens, but now nobody can tell if you're wearing a pair of bifocals or a trendy pair of Burberry single vision sunglasses. The London-based fashion house of Burberry is known for their trench coats and tartan patterns, but their fashion expertise also extends to their long line of Burberry prescription sunglasses. Progressive sunglasses by Burberry come in a number of distinct Burberry glasses frames; choose from aviators, wrap-around sport glasses, or large lens fashion glasses in a number of different polarizations, tints, and finishes. To combine the vision versatility of standard bifocals with the chic look of a normal pair of sunglasses, try out a pair of Burberry progressive lens sunglasses.
