The biggest thing to note when buying a different size in a New Wayfarer is the design change over the sizes. What we mean by that is, the bigger the size, the less tilt in the lens. So, from the smallest size 52 (52mm width lens) you get a shorter lens. One more reminiscent of the Original 2140. But more importantly, you get more of a tilt too.

The Original Wayfarer has 2 sizes. 50 and 54. This is 50mm width and a 54mm lens width. As a general rule of thumb, the 50 is a standard fit, and will fit most faces. The 54mm is a large fit and caters for those with a larger face. The New Wayfarer is, as the name suggests, the newer, younger brother of the Wayfarer. It looks similar but has a more modern feel and approach. Mainly, the traditional tilt is less. It also boasts more sizes than its older brother. Norris, Scott.

[7] The design was inspired by, "a mid-century classic to rival Eames chairs and Cadillac tail fins." [5] According to design critic Stephen Bayley, the "distinctive trapezoidal frame spoke a non-verbal language that hinted at unstable dangerousness, but one nicely tempered by the sturdy arms which, according to the advertising, gave the frames a 'masculine look'." [5] The sunglasses also featured a new plastic molding technology.

Therefore, the lens size won’t be printed on the inside of the arm. Ray-Ban Wayfarer Sizes Oppenheimer, Jerry. Front Row: Anna Wintour, the Cool Life and Hot Times of Vogue's Editor-in-Chief.
