In optics, a relay lens is a lens or a group of lenses that receives the image from the objective lens and relays it to the eyepiece. Relay lenses are found in refracting telescopes, endoscopes, and periscopes to optically manipulate the light path, extend the length of the whole optical system, and usually serve the purpose of inverting the image. They may be made of one or more convention… WebThe optic nerves relay messages from your eyes to your brain to create visual images. They play a crucial role in your ability to see. Millions of nerve fibers make up each optic nerve. …
