To determine the lens size of Ray-Ban sunglasses, you can check the inside of the temple arm, where you'll usually find a series of numbers. The first number typically indicates the lens width in millimeters. For example, in a size designation like "50-20-140," the "50" represents the lens width. Additionally, you can also find lens size information on the official Ray-Ban website or by consulting the product specifications for a particular model.
You can purchase Ray-Ban Aviator replacement arms from several sources, including the official Ray-Ban website, authorized retailers, and eyewear specialty shops.
