Design pinhole glasses: "See sharp", regardless of your eye sight. With sun glasses effect.
Pinhole glasses (also known as stenopeic glasses from the Greek words for "little opening") are not made of glass at all but of an opaque substance such as metal or plastic. The user looks through any of the many small holes in the material. These holes have the effect of reducing the width of the bundle of diverging rays (called a "pencil of light") coming from each point of the viewed object. Normally, the full opening of the pupil admits light. It is the improper bending of the outermost rays in that pencil of light which causes refractive errors such as myopia, hyperopia (farsightedness), presbyopia (diminished focusing range with age) and astigmatism to be noticeable. Pinholes can bring about clearer vision in all these conditions. By blocking these peripheral rays and only allowing into the eye those rays which pass through the central portion of the pupil, any refractive error in the lens or cornea is not noticed as much. The pupil may be wide open but only the central portion is receiving light. The improvement in visual acuity can be striking.
Highlights of the "Scharfblick" pinhole glasses
Stylish design frame (unisex) which encloses all around (and thus prevents seeping in sidewise penetrating light)
2 mm strong pinhole disc for clear sight (with thin pinhole discs, unwanted seeping occurs)
Inclusive high quality artificial leather storage bag with belt clip
Free shipping due to a order value of 100.00 when delivering to Germany.
