These thin strands of glass are a scientific breakthrough that has made it possible for us to connect with anyone around the ...

I have confidently helped patients navigate the IOL selection process for both cataract surgery and refractive lens ...

These inherent constraints in the optical properties of natural materials have driven the development of artificially engineered metamaterials which rely on the phenomenon of negative refraction.

Although we generally assume that opacity is the normal look for animals like us humans, this factoid is only correct for as long as you maintain the dissimilar optical refraction indices of skin ...

A research team from the University of Jena has developed a tiny optical lens, just a few millimeters in size, that can change its refractive behavior in the presence of gas. The researchers ...

Although we generally assume that opacity is the normal look for animals like us humans, this factoid is only correct for as long as you maintain the dissimilar optical refraction indices of skin ...

Researchers have now developed an optical component that enables highly ... Conventional curved lenses, which direct light by refraction in glass or plastic, are often bulky and heavy, offering ...
