Multi-View style 28 is a modified rectangle female oriented design. Available in three colors, this is an optical computer reading glass frame that you'll love. Multi-View computer reading glasses feature specially designed lenses that allow you to see both close-up AND intermediate objects clearly and comfortably. The thin, light weight lenses automatically change in power without any lines! Plain readers only correct for your reading distance. Objects that are just inches further away may appear blurred or even distorted. Generally, you sit 24 to 30 inches from your monitor, a distance beyond the functional range of your reading glasses. Our Multi-View lenses are multi-focus lenses with two levels of magnification for near and intermediate distances. Order your normal reading glass strength which and the lens will have this power on the bottom of the lens, with a .75 power difference on the top 1/2 of the lens. If you normally wear a +2.0 strength, your Multi-View lens will have a +2.0 on the bottom of the lens and a +1.25 on the top 1/2: basically a no-line multifocal (occupational) lens. They're great at the computer but they're also very useful for the person who doesn't want to look like they're wearing bifocal reading glasses. Frames are high end optical quality with spring hinges. Includes a hard case, cleaning cloth and glass clip. Style 28 is sized for the average female head size.
