A microlens array includes plural powered microlenses or microlens elements for tilting different light-emitting elements or portions of a light-emitting device. Each microlens or microlens element both has optical power, and adjusts the tilt of the wavefront so that in combination the individual microlenses act like a more complex multiple-element optic where each element shifts light from only a portion of the light-emitting device. Such an optical device may be incorporated into eyewear for projecting subtitles or other information above or below a far-away image, such as on a movie screen. Another potential use of the microlens array is for use in a heads-up display. Still another potential use for the microlens array to provide soft focusing of emitted laser light to achieve a target light spot of a desired diameter.
