Tunable Fluidic Lenses with High Dioptric Power for Impaired Vision (1710.04074v1)

Abstract: We report experimental and theoretical results on the production of macroscopic fluidic lenses with high dioptric power, tunable focal distance and aperture shape, for applications in adaptive eyewear for the sub-normal vision segment. The lense is 17 mm wide and is made of an elastic PDMS polymer, which can adaptively restore accommodation distance within several centimeters according to the fluidic volume mechanically pumped in. Moreover, the lens can provide for magnification in the range of +25 Diopter to +100 Diopter with optical aberrations on the order of the wave-length, and overall lens weight of less than 2 $g$. We argue that these features make the proposed lenses appropriate for the impaired vision segment.
