Why are magnifiers made with optical acrylic material instead of glass?
The main reasons for using acrylic instead of glass are cost and weight. Glass lenses are much more expensive to produce then acrylic lenses. Between glass lenses and acrylic lenses, acrylic lenses weigh about one-half that of glass lenses. Exceptional clarity and resistance to ultraviolet light, degradation and discoloration make the acrylic used in Ultra lenses the standard in the industry. These resins are virtually unaffected by alkalis, hydrocarbons, non-oxidizing acids, salt water, photographic or battery solutions.
