Ray-Ban Clubmaster Folding sunglasses combine unmistakable retro style with a new functional design. This foldable version of the Clubmaster can be easily folded and stored for ultimate convenience - although we know you'll want to permanently showcase them! Clubmaster Folding RB2176 sunglasses are as timeless and fashionable today as when they were first introduced and became the sunglass of choice of counter-culture intellectuals.

The lenses are distortion free thanks to the diamond tools that shape them and offer the wearer true UVA & UVB protection, together with also blocking harmful Blue light up to 400 nanometers.

Gradient-Mirror lenses combine a mirror and a base lens color to create a two-toned faded effect..


Lens Size
Ray-Ban Clubmaster Folding are available in a large 57mm, regular 51mm and a small 49mm lens size. This is the regular 51mm version

Clarity & Comfort
Crystal lenses with anti-reflective coating have been shaped by Diamond Tools and offer distortion free vision.

UV Protection
Every lens blocks 100% UVA, UVB & harmful Blue light (up to 400nm)

Impact Resistance Lens
A steel ball is dropped on the lens from a height of 1.27m. After the chemical hardening, the impact resistance of Ray-ban glass is more than doubled.

Scratch Resistance Lens
Submitted to 500g of a special abrasive sand oscillating for 600 cycles. Compared to the most commonly prescribed lenses (CR-39), they are 12 times more resistant, thus exceeding by far the international standards

Weatherproof Lens
The Ray-Ban lens is exposed to consecutive cycles of UV light and moisture. The result after 120 hours of intense testing: no visible change in the colour and no surface damages on the lens.

Gradient Lens
Gradient lenses follow the latest style trends in terms of shades and provide a wide range of colors creating exciting and unique looks.
