Lens diameter: 37mm (1 3/8" wide). A pocket, self protected, high quality 5X aspheric lens that not only provides greater magnification, but also an excellent field of view. This lens slides in and out of a hard plastic case. The protective case doubles as a handle while viewing small print, ingredients, pricing, hobby items through this superior Bausch and Lomb lens.
This is a great magnifier that you will never want to leave home without.
