Ray-Ban Erika RB4171 Sunglasses vs Ray-Ban RB2132 New Wayfarer

The New Wayfarer is the safer buy: a current, well-built acetate frame with G-15 crystal lenses that block 85% of visible light and full UV400 protection, and it ships with a case and cloth. The Erika is a lighter, rounder plastic frame with gradient lenses and a unisex fit, but the specific pair described here is heavily used with scratched lenses, so its value depends on replacing them. Reviewers rate the Erika well overall, but owners of used pairs report lens wear; the Wayfarer has the longer track record for durability.

• Choose the Erika if you want a round, softer-looking frame with gradient lenses and you are fine replacing the lenses on a used pair.
• Choose the New Wayfarer if you want a durable everyday frame with dark green G-15 lenses, full UV400 coverage and a case included.
