The Ray-Ban RB3751CH is a square-frame sunglass built around Ray-Ban's Chromance lens, a polarized polycarbonate lens with a multi-layer anti-reflective coating and a hydrophobic treatment. Chromance filters short wavelengths more than standard polarized lenses, so reds and greens read brighter and contrast is stronger. That makes it a good pick for boaters, anglers, hikers and drivers who want glare cut and detail sharpened rather than just a dark tint. Against Ray-Ban's standard polarized models it trades a plainer view for richer color separation; against non-polarized fashion frames it costs more and adds real optical work.

The Ray-Ban RB3751CH is a pair of square sunglasses with Chromance lenses. Chromance is Ray-Ban's polarized lens system, made to increase contrast and sharpen detail. It filters shorter wavelengths more than other lenses, slightly reducing the blue component so colors such as red and green look brighter and clearer. The lenses also reduce glare.
The lenses are polycarbonate, so they are lightweight and impact resistant. They have a multi-layer anti-reflective coating and a hydrophobic treatment that repels water. All lenses block 100% of UVA and UVB rays.
The full-rim frame has a angular square shape and a dual top bar. The temples have six horizontal grooves near the hinges. The front is stainless steel, and the temple tips are propionate. Adjustable nose pads let you customize the fit. The frame suits both men and women. The Ray-Ban logo is etched on the lens and embossed on the temples. The sunglasses can be fitted with single-vision or progressive prescription lenses that keep the Chromance polarized performance.
