Lens Strength Definition. That means a lens with a focal length of 1/2 meter will have a diopter strength of 2. Diopter strength refers to the optical power of a lens. The abbreviations and numbers on your eyeglass prescription describe the type and strength of lenses you need, and the degree of nearsightedness, farsightedness, or astigmatism. Human calculation or a computer?. To put it simply, knowing how they relate clarifies lens strength and makes precise measurements and prescriptions possible in photography, optometry, microscopy, and. When preparing for cataract surgery, how is the lens power or strength determined? We’ve said magnification measures the change of an object’s size whenever it’s being viewed through an optical device, while the diopter measures the. A focal length of 1/3 meter will have a strength of 3 diopters. As we said in our definition, the diopter strength (power of the lens) is the reciprocal of the focal length. The most important characteristic of a lens is its principal focal length, or its inverse which is called the lens strength or lens power.
