A designing and fabricating method of optical lens set comprises: establishing a set of known parameters of a properly focused known optical lens set; inputting an image height value to be changed; calculating a corresponding lens thickness value and a corresponding air space value based on the input image height value; and, fabricating a new optical lens set based on the calculated lens thickness value and air space value so as to fit with the input image height value. That is, the method of the present invention needs only to change the thickness and air space of lens for achieving the effect of changing the image height. Because the thickness of lens can be modified by simply adjusting the interval between the male and female molds during its manufacturing process; and, the air space of lens can be adjusted by simply inserting washer with predefined thickness between the lenses, such that there is no need to re-design the molds for producing the new optical lens set at all.
