• how do fitness trackers workSunglasses allow better vision in bright daylight, and may protect one's eyes against damage from high levels of ultraviolet light. 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. Martin Nettleton adds: “We invested in the campaign to target those larger installation and distribution companies increasingly dissatisfied with the big fabricators who are starting to compete with them by setting up their own networks of trade counters and distribution outlets. The British Glass entry features its three-year programme to facilitate collaboration between glass manufacturers and government to create a decarbonisation action plan – setting out the sectors’ priorities for energy efficiency and decarbonisation in areas such as research and development, technology implementation, energy infrastructure, recycling, skills and funding. In April of this year all ten of the UK’s large-scale glass manufacturers signed up to the voluntary action plan. This beautiful bespoke bottle was designed by M&E Design. It perfectly demonstrates how glass can be used as a vessel for ambition, style, and sophistication. The bottle was created with none of the usual visual cues of a standard whiskey bottle. Instead, it was crafted to celebrate the liquid inside and the process behind its creation. The design takes its cues from laboratory glassware found in the micro-distillery and the paneling of a whiskey cask. It has been shaped to refract and bounce light. The side panel embossing produces a Kaleidoscope of patterns within the body of the bottle, bringing Method and Madness together.
