The Black Eye Pro Kit consists of a clamp and 3 lenses for your smartphone camera. The clamp fits on your smartphone's lens like a clothespin. This set contains a telephoto lens with 3x zoom that makes it seem as if your subject stands out from the background. The fisheye lens gives your photos a convex appearance. The HD macro lens with 15x zoom lets you get in close to take sharp, detailed photos of your subject. The coating on the lenses combats reflections and visual distortion.
