An automatically adjusted magnifier for a display comprises a motor, two movable bases, two breakers, and a magnifier. The movable bases are located at either sides of the motor to connect with the motor by way of gears. Each of the movable bases has a transmission belt driven by the motor via one of the gears and a driving wheel to carry two opposite pulleys moving along a guide rail respectively. Two extensible levers in each movable base have an end thereof pivotally attached to the pulleys respectively and the other end thereof pivotally attached an engaging piece respectively so as to connect with the magnifying glass. Hence, the extensible levers may displace the magnifying glass to a best position to magnify a screen of the display.
