With the cornea it helps to refract light to be focused on the retina.
"In contrast, a tropical sea is crystal clear, with almost nothing suspended in the water to refract light or block our view," the spokesman said.
Since water refracts light differently than air, each drop will act like a magnifying lens, shifting the plane of focus from the film.
Other ingredients may disperse or refract light so that the skin's surface appears more uniform.
The eye achieves this goal by adjusting a lens behind the cornea to refract light appropriately.
It refracts light and protects the contents of the eye.
In a glance she saw that a negative-ended wormhole refracted light oppositely.
The crystalline lens is a transparent, biconvex structure in the eye that, along with the cornea, helps to refract light to be focused on the retina.
These systems use a directed light source or refracting light to measure height, area, and volume.
Windows made of thick glass that refracted light both inside and out in subtle flashes of purple and blue.
