The contribution presents a real scene imaging by a lens coupled with the light sword optical element. The experiments give evidence that the light sword optical element is a very promising device for compensation of presbyopia of the human eye.IntroductionAfter an age of 50 years the human eye loses its accommodation ability. This phenomenon is termed as a presbyopia. It means that it is necessary to use glasses anytime one wants to observe near objects. The most common solution of this problem is to use multifocal or progressive lenses. Some parts of them have imaging properties designed for near objects (reading) and other parts are appropriate for distant objects. Unfortunately, when ability of a human eye lens to change its optical power does not exist then a multifocal lens can image sharply objects located in only discrete distances. Most often it is 2-3 specific distances depending on a design. Axicons and axilenses are designed for continuous range of object distances but images formed by them have usually a very poor contrast and their quality strongly depends on an aperture diameter [1,3]. This problem does not exist when we substitute a radial modulation of the optical power by an angular one [1,3].
