The bridge is the center of the frame that rests on your nose and joins the Hinges. The hinges, which sit between the end pieces and the temples, allow you Lenses. Lenses are the clear pieces of glass, plastic or other material held in place Screws. The screws are the small metal fasteners near the hinges that connect the Nose pads. The nose pads are the round plastic pieces under the bridge that sit on Pad arms. The pad arms extend from the rims and hold the nose pads in place. Temples.

They are simple constructions with an a array of glass pieces, arranged in a specific order, to allow light to pass from one end to the other and ultimately into your camera.Lenses 101 - An Introduction to Camera Lenses What kind of materials are used for eyeglass lenses?What kind of materials are used for eyeglass lenses?In the United States, most high index lenses are made from the various plastic materials. Some other countries still use a lot of glass material for high index lenses. Glass is available in very high indices such as 1.8 and 1.9 but because of its density it is still very heavy . Glass lenses also take longer for optical labs to fabricate.Eyeglass Lens Materials - Master Eye Associates

What are the optical principles of a lens?What are the optical principles of a lens?Optical principles for lenses. The focal length of a lens is the distance from the centre of the lens to the point at which the a distant object is formed. A long-focus lens forms a larger a distant object, while a short-focus lens forms a small image.lens Meaning, Principles, Manufacture, & Facts Britannica Understanding Optical Lens Geometries Edmund Optics

Optical lenses come in many shapes and sizes from plano-convex (PCX) to aspheric. Knowing the advantages and disadvantages of each lens type is crucial when choosing between optics as each has its own purpose. Understanding optical lens geometries helps anyone, from novice to expert, choose the best optical lens How are the different types of lenses different?How are the different types of lenses different?In the next section, let us discuss the different types of lenses. The classification of a lens depends on how the light rays bend when they pass through the lens. The two main types of lenses are Convex lenses are thick in the middle and thinner at the edges. A concave lens is flat in the middle and thicker at the edges.Lenses in Optics - Applications Types of Lenses Physics
