Nowadays the frames used for prescription glasses which are considered as big a fashion accessory as your purse can be generally classified into three main categories: Full rim, semi-rim and rimless frames. And rimless frames have become the widely used and most popular choices for prescription glasses wearers since they can make you feel wonderful in terms of both fashion and function.
Most of the rimless frames for prescription glasses are comprised of very limited materials including two lenses, the nosepiece and very thin support arms (with such structure, the burden on the nose has reduced to a great extent.) The prescription lenses are always connected by the temples and the bridge. As to the frame materials, metal should be the main ones used for these rimless frames without doubts. And titanium have become the most salable among all the metal materials by the advantage that compared with other materials, the prescription glasses frames made of titanium are more lightweight and durable.
As is known to all that not all of the frames can be perfect for everyone, but the structure of the rimless prescription glasses frame has given people a much more available options. Different from the full rim or semi-rim frames, rimless prescription glasses only covers quite a few part of the wearer’s face which allows the prescription glasses wearer to show their natural look as much as possible and you may feel that you almost wear no glasses at all. Furthermore, the rimless frames are also considered to be the most comfortable styles to wear for prescription glasses due to their simply structure and lightweight advantages.
Concerning that the rimless prescription glasses frames are far more fragile than full rim or half rim glasses, we should pay special attention when choose the lenses for these prescription glasses. Generally speaking, if you choose standard CR-39 lenses for your rimless prescription glasses, the lenses will easily get crack for a long time in the future use. So you had better choose the lenses with more durable lenses which can effectively protect the lenses crack. Among all of the lenses materials for the prescription glasses, Polycarbonate lens which is the lightest, most impact-resistant material made are strongly recommended for your rimless prescription glasses.
