Vintage Persol 830 sunglasses feature a beautiful yellow tortoise shell frame that it seems only the Italians can do properly, combined with the fine optical quality inherent in original Persol brown mineral glass lenses. Persol 830 sunglasses are a little more rounded than many vintage Persol styles, softening the more angular look in other models and complementing a variety of face sizes and shapes. These Persol Ratti 830 sunglasses incorporate the Meflecto system unique to vintage Persols, 4 metal pins which are inserted vertically into the ear stems and provide unparalleled flexibility in the stems for perfect comfort and fit. The unisex Persol 830 sunglasses frame measures approximately 5.5" temple to temple, and the lenses measure approximately 2.0" x 1.375" at the widest points with both lenses laser etched with the round Persol mark in the upper outside corners. You'll find the distinctive silver metal Persol arrow on the exterior of both ear stems wrapping around the temple.
