(2), as near objects: the first for about 45 degrees with the horizontal plane, under the eye forward, through the lens bottom (as the near area) to see objects, see if it is not clear, your eyes turn a little or adjust the head position, usually raise the head position is, until you find the best area to see a close. (3) depending on the distance of objects: the eyes look from the middle of the lens, the distance to the next transition area from the above corresponds to each point each from far to near distance, therefore, to see objects more than 0.5 m at 3 meters to see the object, the eyes It is necessary to turn some more. 2.
