The level of seeing objects should be changed to 'Farther, smallest,' and efforts of intense cognitive concentration should be made at this distance. The 'Farther, smallest' implies a blurry and dim distance or sample size -farther than one's own focal length, and smaller than one's own focal spot size. The movement of the eye lens is automatically controlled by cognitive concentration according to the level of ability to see objects. Those with decreased eyesight have a decreased ability to see objects, and mostly are myopian. Their ciliary body is under tension due to overstraining low-level environment, and they lack mental concentration. Their environment should be changed; their viewing distance should be shifted to higher levels; and they should concentrate.
