With a classic rectangular shape, a pop of color, and a matte finish that looks good on everyone, Carrera 6637N reading glasses have a saddle bridge and spring hinges for a comfortable, flexible fit. The Carrera logo on the temples adds just a little flash. The optical-grade distortion-free lenses are correction-free at the top, with increased magnification for intermediate and close-up viewing. Every pair of Carrera reading glasses comes with a signature protective carrying case and a microfiber cleaning cloth.
 Your New "No Line" Lenses, also known as Progressive Lenses, will provide a clear, comfortable close up vision, without a line of sight.

The Upper portions of your lenses are clear. As you lower your eyes, the magnification increases gradually allowing you to see better at different close up distances.

    OK but way you to expensive

    The cost is way to steep .I have reading glasses that I bought at the dollar store for a buck that work just as good . If not better. However they seem to be good quality frames ,I like the no line bifocal so I don't have to be taking them on and off all the time and the photocromic lenses are great because I work outdoors half the time . Overall I like them but the prices need to come down .there reading glasses for goodness sakes !

    I get compliments wearing these. They are light weight and have a decent sized viewing area.
