We presented a paper describing some of the core ideas behind our lens design algorithm in San Diego at the SPIE Current Developments in Lens Design and Optical Engineering.
Higher-order wavefront correction
With completely custom lens surfaces comes the opportunity to try and address higher order aberrations. The changing gaze angle of the eye during normal vision makes correction difficult in general use. However, researchers have claimed some improvements in vision using
Fast & Robust Wavefront Sensing
Rapidly rising levels of myopia, particularly in the developing world, have led to an increased need for inexpensive and automated approaches to optometry. A simple and robust technique is provided for estimating major ophthalmic aberrations using a gradient-based wavefront sensor.
Zernike Polynomials
Truncated expansions such as Zernike polynomials provide a powerful approach for describing wavefront data. However, many simple calculations with data in this form can require significant computational effort. Important examples include recentering, renormalizing, and translating the wavefront data.
