With all the continuing development of prescription glasses, more and more different designed eyeglass frames have grown to be available. Normally, frames may be split into three different kinds – full rim, semi rim and rimless. Many individuals may ask about which frame type is best after they prepare to buy the prescription glasses at stores or online stores. Actually, each frame type possesses his own features.
Full rim eyeglasses, otherwise known as “hide-a-bevel” eyeglasses. They are not only the most original eyeglasses but also the most typical and used designs. They encircle the prescription lenses completely; hold the lenses tightest, and in addition designed for the thinnest prescription lenses. The total rim eyeglasses frames do an adequate job of avoiding the edges from the lenses exposed; those are the good option in case you have strong prescriptions.
Semi rim eyeglasses frames, also referred to as “grooved” frames, only cover half the prescription lenses. There are nylon strings or liners running along the bottom from the prescription lenses to keep the lenses, hence the semi rim frames are lighter than full rim frames. Because of these frames, whenever we assemble the prescription glasses, we should instead cut grooves to the prescription lenses edges. For this reason, the thicker lenses are expected for your semi rim eyeglass frames so we don’t chip and crack.
Rimless eyeglass, since the name implies, have no rim. The lenses are joined by the nose bridge and also the temples are joined towards the lenses on the other ends. The rimless rim eyeglass will be the lightest eyewear. They are timeless since they are very easy, thus making you look confident and versatile. But as a result of there is absolutely no rim all around the lenses providing sufficient protection, they are least durable. Additional, the rimless eyeglass frame put high level of force on the prescription lenses, so it will be recommended that CR39 lenses must be avoided to utilize, and also index lenses with better durability are recommended for example polycarbonate lenses.
