Persol glasses frames could almost be considered works of art. Persol Eyewear has been in business since 1910, and they've been honing the craft of innovative frame making for their entire history. A number of innovations separate these glasses frames from those of the competition. All plastic frames are constructed of acetate, a cotton flower derived material that's allergy free, warm to the touch, and pleasant on the skin. Many steps in the production of Persol frames can only be done by hand, due to the high level of artistry inherent in each pair of Persol glasses. The bridge of each pair of glasses is smooth and rounded due to the "telatura" process, which has been in use since the founding of the company. These glasses also utilize Meflecto technology, which allows comfortable bending of the frame's stem to adhere to each individual's facial structure, giving each user a "custom fit" that totally maximizes comfort. All these features make a pair of Persol prescription eyeglasses wearable, but these frames are also stylish; choose from dozens of designs, frame sizes, and custom details to make an utterly tailored, utterly unique pair of glasses for everyday use. When you want a quality guarantee and a tradition of excellence, go with Persol eyeglass frames.
