As I personally love most of BLVCK Paris’ products, this accessory is by far the most beneficial purchase I have made. I know that I have them on my face solidly as they grip to your face on the sides. So I can look down & anywhere without having to worry they will fall. I work as a valet so they are the perfect for me even when jogging to vehicles & back. Honestly they are worth the money & I feel like they are not to tinted but just enough to not see my eyes with a nice contrast as you go further up.
