How to Choose Glasses Glasses With Size
Glass size usually consists of lens size (size / horizontal lens width) and the size of the bridge (the bridge of the nose width.
The size of the lens in terms of health is useful for students agan agan position right in the middle of a focusing lens, useful for agan more comfortable vision and focus. The size of the lens is closely related to PD (in the shade Distance: the distance between the pupil right-left). For more information please see spoiler "way to measure PD". In terms of the size of the lens correction mode is also useful for those who have minus / plus high. For those of you who reduced / plus tall glass sizenya should choose a small or a thick frame, this serves to cover the thickness of the lens so as not to appear.
A handy size for agan bridge can determine the position of the glasses on the nose comfort agan. For those of you who nosed (sorry) select the frame with a small bridge or with nosepad (nose pads) that can be adjusted, so that the position can be adjusted holder nosepad with agan nose.
The size of the glasses are usually printed on the handle side of the glasses, but there are also listed in the bridge (bridge of the nose) or in nosepad (nose pads) on a plastic frame. In addition to the lens and the size of the bridge, there is also the length of the size of the temple (long stem) and vertical lens (lens height). But the high lens is not printed on the frame.

Stem length is generally adapted to the shape and size of the frame and nearly all long-stem glasses frame 135-145 mm. Why not really important? Because the length of the rod can be adjusted, by means of bent or straightened to get the right size of our heads. Likewise with the vertical (height) lens. vertical lenses are usually made in proportion to the size of the existing frame. There my customers asking vertical frame size 48 to 36 (in mm; millimeters) is very strange, very, very disproportionate. Try agan took a ruler and a picture / imagine shapes! So, my advice is not to ask the lens vertically or ask for something that is not proportional, because instead of cool is not going to look strange
