The lens width of the classic Ray-Ban Wayfarer is 50 millimeters. The standard Original Wayfarer Classic is commonly identified by its 50-22 sizing: 50 mm lens width and 22 mm bridge width.
Ray-Ban introduced the Wayfarer in 1952. American optical designer Raymond Stegeman created its trapezoidal plastic frame for Bausch & Lomb, giving the glasses a distinct alternative to the metal aviator styles of the period.
A common mix-up is confusing the classic Wayfarer with the New Wayfarer or larger versions of the Original model. Some Wayfarer variants use wider lenses, including 54 mm sizes, while low-bridge-fit versions may use other dimensions. The 50 mm answer refers to the standard classic size, not every Wayfarer ever produced.
The design nearly disappeared in the 1970s, then returned to prominence through film and television placements. Tom Cruise’s appearance in Risky Business helped make the Wayfarer a defining 1980s accessory.
