Abstract
A lens, an optical display device including the lens, and a method for manufacturing the lens. The lens includes at least two lens portions; which have different focal lengths. When human eyes view a real scene image through the at least two lens portions separately, the real scene image is imaged at different image distances. The lens includes different lens portions having different focal lens, and thus can be a multi-focus lens. When the lens is used for an optical display device, the human eyes will see virtual image planes at different distances when viewing a display picture through the different lens portions due to the different focal lengths of the different lens portions. Visual fatigue can be reduced, and also scene images at difference distances can be appropriated, so that the three-dimensional feeling is improved.
