How I hope that I have a pair of binoculus with me. So I decided to create a ?Binoculus? me ? I made a fist and put it against an eye while closing the other eye. I opened the fist just enough to create a small hole to look through. Wow, I did in fact, I could see more clearly in this way. The name of ?Pinhole glasses?, you will probably think they are made of glass. In addition, they are really opaque metal or plastic, numerous small holes on the hardware.
When the user searches by the any of numerous small holes, these holes reduce divergent rays beam width from each point on the object view. The student can be wide open, but only the central part receives light. Improving visual acuity can be striking.
Good news is that pinhole glasses bring clearer vision in the eyes of refractive errors like nearsightedness, farsightedness (hyperopia), presbyopia (range focusing decreased with age) and astigmatism.
Indeed, the indigenous peoples of Alaska have long used this principle by wearing sunglasses with narrow slits to watch, thereby blocking much of the brightness of the Sun reflecting off the coast of snow and ice.

3 Divert your attention with a hole in your glasses. So concentrate on during 3 seconds.
4 Repeat step (2) and (3) for approximately 7-10 minutes per day.
5. At the end of eye exercises, do Nordic for 3 minutes or more.
When your vision is improved, the time needed to refocus to close to be shorten. Slowly increase the distance of graphic vision on your part.
