These are the original Brioni Horn arm sunglasses with the aviation class Carl Zeiss lenses. No longer manufactured due to cost-cutting from Kering. One of the quirks of these sunglasses was that the tips of the horn arms would leave marks on the oleophobic coating on the inside of the lenses(superficial marks only, not tactile).

You can buy replacement lenses at many places for these, but for all intents and purposes, they are fine, the marks in no way impact their use. Selling them below cost.
