WebMar 13, 2024 · The index of refraction is different between air (~1) and glasses (~1.3). This difference is what makes "air" glasses function. The problem is that water has a refractive index of ~1.3 as well. Now there's hardly any difference in index of refraction between the glasses and water so light hardly bends. How does this work?

WebLenses serve to refract light at each boundary. As a ray of light enters a lens, it is refracted; and as the same ray of light exits the lens, it is refracted again. The net effect of the refraction of light at these two boundaries is that the light ray has changed directions. Because of the special geometric shape of a lens, the light rays are ...
