Embodiment of iconic woman's fashion and celebration of individuality one is capable of achieving are the values Bertha Gleisner strove to express in her family's jewelry shop during the decadent 1920's. Today we carry on her legacy with products that radiate contemporary glamour. By creating new timeless styles with trendsetting designs, Bertha products are crafted for the rare ones.
While working in her family's jewelry shop, Bertha admired antique jewelry made from horn of the Asian water buffalo. The unique, natural and beautiful patterns give an exotic, yet refined look. Bertha Horn Sunglasses are handcrafted from natural horn, a superior material that is naturally lightweight and strong, and develops a beautiful patina with age. A material with such a rich history has now been brought to everyday luxury with Bertha Sunglasses.
Caring for your Handmade BERTHA Horn Sunglasses
Please use a soft cloth and a mild soap to wet and dry the frame. Never soak your sunglasses. To maintain the unique luster and to assure the frame does not become brittle we suggest rubbing baby oil on the frame before sleeping and by the time you awake the frames will be fully rejuvenated.
Type of lenses
Quality sunglasses offer a polarized lens. All of Bertha sunglasses are polarized and we use the Triacetate Cellulose (TAC) polarized process. The TAC process uses a multiple layer production.
Polarized lenses have the benefit of filtering out reflected light and glare off water, pavement and snow. TAC polarized lens are superior for fishing, boating, driving or any other glare intensive activity. TAC polarized lenses are the best ways to eliminate glare and UV light. Polarization is achieved by shutting out 100% of undesirable light and allowing 100% of desired light through the lenses.
Multi-layer composite complies with the international sunglasses lenses standard and UV400 UV sunglasses lenses standard. Thus, the polarized lenses can fully protect eyes. The first layer is a polarizing layer; core of the lens as it provides more than 99% of the polarizing effect, which can effective absorption of glare. Second and third layer for bonding, can effectively resist the cutting, baking, baking bend, cut pieces, tests of withstanding harsh environments. The fourth and fifth layer for UV-absorbing layer; absorbing 99% of UV-ultraviolet rays. The remaining layers perform shock-proof protection as the layers increase toughness, impact resistance, preventing lens scratches and extend the life of polarized lenses
Layers of protection
TAC produced lens are ultra-light and are highly impact resistant.
TAC polarized sunglasses lenses are effective cutting strong light, reflection and scattering light. It makes light rays become parallel. TAC polarized lenses makes the scenery more clear and soft. Bertha sunglasses have zero distortion of scenery and the feeling of vertigo.
