The document discusses how prisms work to refract and disperse light. When light travels from one medium to another with a different density, such as from air into glass, it changes speed and is refracted. This refraction causes dispersion, where different wavelengths of light are bent different amounts. As a result, white light entering a prism separates into the visible color spectrum. Prisms are useful for applications like spectroscopy due to their ability to disperse broad spectrums of light without issues from overlapping orders like diffraction gratings.

Lightspecs Lloyd Reading Glasses with a lightweight nylon frame are great when performing near tasks in dark or dimly lit environments, providing magnification as well as bright LED illumination. These are perfect to read in bed, or for reading menus in dimly lit restaurants.Each pair features 2 LEDs (one on each temple) that are each individually activated with an easy flick of a switch on the inner temple and powered by two flat button-sized batteries that last on average 50 hours. The batteries are also easily replaced. Foster Grant® is the most trusted brand in eye wear, offering a wide variety of fashionable and classic styles in reading glasses for both men and women. Foster Grant® is always innovating the categories with new styles including the latest frame materials, advanced lenses, new styles and designs with new, on-trend colors.
