Some demonstrative embodiments include apparatuses systems and/or methods of determining one or more optical parameters of a lens of eyeglasses. For example a product may include one or more tangible computer readable non transitory storage media including computer executable instructions operable to when executed by at least one computer processor enable the at least one computer processor to implement operations of determining one or more optical parameters of a lens of eyeglasses. The operations may include processing at least one image of an object captured via the lens; and determining the one or more optical parameters of the lens based on the at least one image.
