1. A method of determining one or more optical parameters of a lens of eyeglasses, the method comprising:
displaying an object using a display device;
positioning a lens between an image-capturing device and the object of the display device;
capturing an image of the object via the lens when the lens is between the image-capturing device and the object, the image comprising a plurality of axes, the plurality of axes including a plurality of visible intersecting radial lines;
determining a maximal magnification axis of the plurality of axes at which a magnification between an imaged dimension of the object in the image and a reference dimension of the object is maximal for the plurality of visible intersecting radial lines;
determining a minimal magnification axis of the plurality of axes at which a magnification between an imaged dimension of the object in the image and a reference dimension of the object is minimal for the plurality of visible intersecting radial lines;
determining a cylindrical power of the lens based on the maximal magnification axis of the plurality of axes and based on the minimal magnification axis of the plurality of axes; and
producing a second lens having the cylindrical power of the lens.
