Pinhole Glasses See clearly, using Pinholes may reduce strain Without Pinholes In a weak eye, light rays entering the eye's lens are not all focussed onto the same place on the retina. For example rays a, b, f and g require more focussing by the lens to hit the same plane as rays c, d and e which are nearer to the centre.  Rays c, d and e are usually in focus, regardless of the condition of the eye, and for a clear image on the retina.  This clear image is flooded by the blurred image formed by rays a, b, f and g. With Pinholes When the pinhole lens is used, only rays c, d and e are allowed to form an image on the retina and no blurred image is present to block the clear image.  Consequently, by the using a lens with multiple pinholes, many focused images form on the retina and a clear, natural image is seen.  Also, no effort is required from the eye muscle, as the only rays entering the eye are already in focus.
