+2.00-1.00x Aspheric lenses Correct Answer: Works well for spherical, but is inadequate for Rx with Cyl. Also has a wider field of view, and a thinner lens profile. Multi-focal lenses Correct Answer: A single lens designed with multiple powers to be used at different distances. Bifocal lenses Correct Answer: These lenses have powers for viewing at two distances. In most situations, the top of the lens allows clear vision at distance, and the bottom allows for clear vision at near. Trifocal lenses Correct Answer: These lenses have powers for viewing at three distances. This adds an intermediate viewing. Progressive Addition Lenses (PAL) Correct Answer: Instead of having two or three viewing distances, these lenses gradually change power starting at the top of the lens to the bottom. Glass Correct Answer: Hardest surface, therefore the most scratch-resistant; easiest to break or shatter. CR-39 Correct Answer: Less scratch-resistant, thought most lenses are treated to improve scratch-resistance, but will still scratch more than glass. Thicker than glass lenses, harder that glass to break. Polycarbonate Correct Answer: They are much harder to break or shatter. They are a safety lens for children, athletes, and monocular patients. Thinner than CR-39. Trivex Correct Answer: Mid-Index lens. Thinner than glass, CR-39 and Poly. They are free from distortions and aberrations. High-Index Lenses Correct Answer: The thinnest lens materials and thus provide a better cosmetic appearance for spectacles in higher prescriptions.

Bridge Correct Answer: The part of the frame that connects the two eyewires together and supports the frame on the patient's nose. Hinge Correct Answer: Connects the frame front to the temples. The hinge allows the temples to fold in behind the frame front so that the spectacles will occupy less space and fit into a case or pocket.
Nosepads Correct Answer: Are located on the eyewire, near the area where the bridge is attached. They distribute the weight of the frame onto the sides of the nose to make the frame more comfortable to wear. Temples Correct Answer: Extend from the frame front, back alongside the head, and over the ear of the wearer. Temples are made up of the butt portion, dowel hole, shield, bend, and earpiece. "A" Measurement Correct Answer: Eyesize; the widest horizontal dimension of the lens opening. "B" Measurement Correct Answer: The most vertical dimension of the lens opening. "ED" (effective diameter) Correct Answer: Measures the largest diameter through the lens. By representing the widest part of the lens, you can determine what size lens blank must be used in order to have the lens fit in the frame. Distance Between Lenses (DBL) Correct Answer: Also known as the Bridge size, represents the distance separating the two lenses. Pupillary Distance Correct Answer: The distance between the centers of the pupil of each eye. Seg height Correct Answer: The height of the reading portion of a multi-focal lens as measured from the deepest part of the eyewire to a reference point, such as the lower eyelid or pupil center. Vertex Distance Correct Answer: Describes the distance from the back of the glasses lens to the cornea. Pantoscopic Angle (Tilt) Correct Answer: Refers to the angle the temple of the frame makes with the frame front. The bottom should be closer to the cheeks than the top of the eyewire is to the eyebrows. _______lenses are also called convex lenses. They are thick in the center and thin on the edges. Light rays passing through these lenses will be converged. Correct Answer: Plus lenses _______lenses are thin in the center and thick on the edges. Objects viewed through these lenses will appear smaller or minified. Light rays passing through these lenses will be diverged. Correct Answer: Minus lenses What instrument is used to verify the spectacle prescription?
