Von Zipper Lens Tints:

Von Zipper offers two different lens tints that work equally well when cutting out harmful UV rays and glare, and reducing eye fatigue.

Von Zipper Grey Lenses
The Von Zipper Grey lens tint is a popular choice and specifically engineered to protect against bright sunlight.

Von Zipper Bronze Lenses
The Von Zipper Bronze lens tint offers sumptuous visual acuity for bright light conditions. These lenses are engineered to add depth and detail to everything you see. Von Zipper's bronze lenses are an appetizing choice for sharpness and clarity.

All Von Zipper lenses offer 100% UVA and UVB protection.

Von Zipper Lens Curvature
To achieve the variety of Von Zipper's looks, Von Zipper utilises 4 different types of curves, rated by number depending on the amount of curvature in the lens. The higher the number, the higher the curve, so Base 6 styles give a 'flatter' look, while 8-9 curves hug closer to the face.

Von Zipper Lens Materials:

	Polycarbonate Von Zipper polycarbonate lenses are distortion free, optically correct and maximum scratch and shatter resistant. These lenses offer UV400 protection and are available in grey, bronze, fashion gradients and chrome coatings.

Glass Polarised
Von Zipper Glass Polarised lenses are culmination of their relationship with Barberini S.R.L, the most advanced developer of polarised technology. These lenses combine the optical superiority of glass with the skill and technical artistry it takes to block 99.9% of glare while maintaining true colours and ultra-sharp details.

First, two layers of glass are sandwiched together around an ultra-thin polarised filter and a scratch-resistant hard coating, to protect the lens exterior, is added.
