With the continuing development of prescription glasses, more and more different designed eyeglass frames are becoming available. Normally, frames may be separated into three differing types – full rim, semi rim and rimless. Many people may inquire about which frame type is much better after they prepare to buy the prescription glasses at shops or online retailers. Actually, each frame type possesses its own features.
Full rim eyeglasses, also known as “hide-a-bevel” eyeglasses. They are not only probably the most original eyeglasses and also the most popular and used designs. They encircle the prescription lenses completely; holds the lenses tightest, and also designed for the thinnest prescription lenses. The entire rim eyeglasses frames do a good job of avoiding the edges with the lenses exposed; those are the good choice for those who have strong prescriptions.
Semi rim eyeglasses frames, also called “grooved” frames, only cover half the prescription lenses. There are nylon strings or liners running down the bottom with the prescription lenses to support the lenses, hence the semi rim frames are lighter than full rim frames. Of these frames, whenever we assemble the prescription glasses, we must cut grooves in the prescription lenses edges. For that reason, the thicker lenses are required to the semi rim eyeglass frames in order to not chip and crack.
Rimless eyeglass, since the name implies, haven’t any rim. The lenses are joined by the nose bridge and also the temples are joined on the lenses alternatively ends. The rimless rim eyeglass include the lightest eyewear. They’re timeless since they are very simple, therefore making you look confident and versatile. But as a result of there is absolutely no rim surrounding the lenses providing sufficient protection, they’re least durable. Additional, the rimless eyeglass frame put extremely high level of stress on the prescription lenses, therefore it is recommended that CR39 lenses ought to be avoided to utilize, and also index lenses with better durability are suggested for example polycarbonate lenses.
