Typical sunglasses are darkened for protection against bright light or glare; some specialized glasses are clear in dark or indoor conditions, but turn into sunglasses when in bright light. Most sunglasses do not have corrective power in the lenses; however, special prescription sunglasses can be ordered. Specialized glasses may be used for viewing specific visual information (such as stereoscopy) or 3D glasses for viewing three-dimensional movies. Sometimes glasses with no corrective power in the lenses are worn simply for aesthetic or fashion purposes. Even with glasses used for vision correction, a wide range of designs are available for fashion purposes, using plastic, wire, and other materials. The Method and Madness range includes four new Irish whiskeys. Each whiskey has its own twist; a single pot still Irish whiskey finished in French chestnut, a single grain Irish whiskey finished in virgin Spanish oak, a single malt Irish whiskey enhanced by French limousin oak and a 31-year-old single cask, single grain limited edition bottled at cask strength.
