Vintage B&L Ray Ban Bausch & Lomb B15 Brown Traditionals 。These vintage Baush and Lomb Traditionals Trish Sunglasses are as fashionable as they are functional. They have the Ebony black frame and contrasting B-15 Brown lenses which make a stunning combination. The frames are propionate plastic which were quality tested to last a lifetime with the proper care. They\'re some of the first, and in my humble opinion, some of the most attractive round lenses that Bausch and Lomb ever produced, adding style and sophistication to any ensemble. They measure approximately 5.5\" across the front, and the lenses approximately 2.25\"x 2.5\". Bausch and Lomb lenses are some of the best quality ever made to this day, being \"drop ball\" tested with a 5/8\" steel ball from 50\" above to ensure their impact and scratch resistance. The beautiful B-15 Brown lenses are no exception, they\'re as durable and functional as they are attractive. B-15 Brown lenses are known to greatly reduce glare and cut down on blue light, making them a great choice for driving and outdoor activities such as skiing. They\'re attractive and functional, and look great on anyone. These glasses are in perfect condition having never been worn. Please feel free to ask any questions, and as always, thanks for looking!
