Abstract: A method for improving vision utilizes a progressive series of various diopter eyeglasses, a vision chart or the like, and textual material. The first therapy commences with the person donning a first pair of eyeglasses having a magnifying diopter and the vision chart is positioned approximately 2 feet away from the person. The person then fixates upon the chart mark until the chart mark becomes visually clear. The person then moves farther away from the vision chart by approximately one foot and the person once again fixates upon the chart mark until the chart mark becomes visually clear. The second therapy commences with the person donning a first pair of eyeglasses having a low magnifying diopter and then reading textual material for several minutes. The person then replaces the low magnifying diopter eyeglass with a higher magnifying diopter eyeglass and once again reads the text for several minutes.

Abstract: A mower blade assembly (10) includes an elongated blade bar (11) having two oppositely disposed cutting ends (13). A pair of removable bottom blades (22) and a pair of removable top blades (23) are removably mounted to the blade bar. The bottom blade has two oppositely disposed serrated cutting edges (27) so that either of the two cutting edges may be utilized for cutting purposes. Each top blade has a forward portion (31) which includes a series of blade segments (32) with serrated cutting edges (33) and a series of mulching blades (34) with serrated cutting edges (35). The top blade also has an elongated rear portion (37) that is oriented at an angle with respect to the cutting blades and blade bar. The angle of the rear portion creates or defines an airfoil deflector which increases the vacuum effect of the rotating blades.
