• erosion science Ms Stephens continues: “The new extension has provided a fantastic and really flexible space that thanks to the new PURe® patio doors and windows, can be enjoyed whatever the weather. It’s great to be able to open up the living space and enjoy the close access we now have to the garden but even when the blustery weather that we are so familiar with here in the Yorkshire Dales takes hold, the glazing has provided us with a peaceful and cosy retreat. It’s the perfect space for both work and relaxation and I couldn’t be happier!” Sunglasses 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.
