Noel Alpins, MD: Any future role played by wavefront technology in surface ablation is likely to emulate the same principles that are applied in LASIK surgery. This is likely to be directed to the ...

SEAS researchers have developed a so-called metacorrector, a single-layer surface of nanostructures that can correct chromatic aberrations across the visible spectrum and can be incorporated into ...

Light travels at different speeds based on the medium it passes through. For example, in a vacuum, it travels at 3.0 × 10^8 m/s in a straight line. But when directed towards glass, air, diamond, water ...

The human eye is a simple, but extremely robust, optical instrument. Analysis by sophisticated wavefront-sensing technology and customized ray-tracing has now revealed that the eye is actually an ...
