Geometrical optics, a branch of optics that eschews wave phenomena in favour of ray propagation, continues to underpin advances in lens design and optical engineering. Contemporary studies in this ...

The thin-lens formula proved comparable to the ray-tracing method in IOL power calculations in normal eyes and eyes that underwent refractive surgery. Preoperative prediction of IOL positioning plays ...

One of the oldest problems in optics has been solved. Rafael Gonzalez from Mexico's Tecnologico de Monterrey has come up with an almost comically dense equation that can be used to almost completely ...
