When evolution skeptics want to attack Darwin's theory, they often point to the human eye. How could something so complex, they argue, have developed through random mutations and natural selection ...

Red light therapy may help slow down the progression of macular degeneration. But more research is needed into the long-term effects and safety of red light therapy for the eyes. Red light therapy ...

Optical design software is used by engineers and scientists to perform a variety of tasks, including illumination calculations, laser beam propagation, stray light analysis and freeform optical ...

To overcome this challenge, the researchers developed a new algorithm that creates smooth patterns, which incorporate isolated vortices that do not significantly impact light propagation.
