I've used it three times since purchasing, but it doesn't suit me, so I'm selling it. Since the wearing time was short, it's almost like new. This is the Guy Laroche GP-07 h (Havana). The lenses are non-prescription, so you can use them immediately upon arrival. The lenses are set to blue, but they look like they have gray in them when worn. To reproduce the original lenses, the sunglasses lenses use flat lenses with anti-reflective coating on the back only, to replicate the reflection on the lens surface at the time. (With UV protection)
