Half-frame structure is broadly divided into frames full frame; many Replica Glasses most troublesome problem is to choose which is better suited to their frames; in fact, different styles of frames has different characteristics, of course there are differences occasions , no frame, a combination of frame and folding frame five.
A: Full-frame glasses frames
Full Rim Frame name suggests is a complete package mirror lens ring. For athletes and children wear, due to the lens periphery to be fully protected lens ring, for a variety of refractive lens fitted parameters.
Two: Half-frame glasses frame
The lens ring portion is made of metal or plastic material and internal grooved, inlaid nylon yarn, ring the lower half mirror points with a very thin nylon filament (drawing) as the lower part of the lens ring. Due to the lower half of the lens does not block the lens ring, and the lens edge is too thick will affect the appearance, so small refractive lenses and refractive lens is too large, not suitable for use of such frames.
Three: rimless optical frames
Frame is divided into parts and integrated type. Part-style by a nose (along with nose pads), around two temples (with trailer coupling) form; integrated between the nose and the trailer coupling has connected frame materials, frame materials connected between the nose and the trailer coupling , the nose and the temples connected into one, but there is no connection between the portions of the material and lenses, like between half frame and frameless. Rimless not suitable for small refractive lenses are not suitable for large diopter lens.
Four: a combination of frames
Frame hours before and after two lens ring, usually equipped with a color lens front group after group equipped with lenses for the correction of refractive errors. Time frame is not suitable for high diopters crowd.
Five: Folding frames
Frame generally be in the nose and temple folded, shrink when storing or carrying frame footprint; these frames are generally used for reading glasses.
