These are the LST Contrast Gold Gradient lenses for the Adidas Retego (a376) sunglasses.
Use these lenses to enhance contrast especially within green landscape or on green floor (initially made for golf but also perfect for all outdoor activities). LST Contrast is also an excellent all purpose lens for sunny conditions. These lenses are graded (darker at the top of the lens going lighter towards the bottom of the lens) and have a gold mirror finish.
Recommended use: Sunlight
