Microfeature workpieces having microlenses and methods of forming microlenses on microfeature workpieces are disclosed herein. In one embodiment, a method for forming microlenses includes forming a plurality of shaping members on a microfeature workpiece between adjacent pixels, reflowing the shaping members to form a shaping structure between adjacent pixels, depositing lens material onto the workpiece, removing selected portions of the lens material adjacent to the shaping structure such that discrete masses of lens material are located over corresponding pixels, and heating the workpiece to reflow the discrete masses of lens material and form a plurality of microlenses.
