Ray-Ban: Ray-Ban Rb4640 Sunglasses Transparent Grey Frame Grey Lenses 50-20 (Review)

Half Off Ray-Ban Sunglasses

Ray-Ban lists the RB4640 Sunglasses with a transparent grey frame and grey lenses (50-20) at $116.50, down from $233.00 — 50% off. Black Friday is on November 27, so it is a good time to ask if the price might drop further.

Reading the Product Name

RB4640 is the model number, and "50-20" refers to the lens width and bridge width in millimeters, a standard way of describing eyewear sizing. Compare those numbers with a pair that fits you well, and check the product page for frame shape and lens details.

Buy Now or Wait?

A 50% markdown is already a strong discount for a premium brand. Black Friday might bring an additional promotion, but a specific model and color can sell out or be discontinued, and premium brands do not always discount further.
