Together with the growth and development of prescription glasses, a lot more different designed eyeglass frames have grown to be available. Normally, frames may be separated into three different kinds – full rim, semi rim and rimless. A lot of people may inquire about which frame type is best once they prepare to get the prescription glasses at retail stores or websites. Actually, each frame type has its own features.
Full rim eyeglasses, otherwise known as “hide-a-bevel” eyeglasses. Also, they are probably the most original eyeglasses but also the most common and used designs. They encircle the prescription lenses completely; holds the lenses tightest, as well as designed for the thinnest prescription lenses. The complete rim eyeglasses frames do an adequate job of avoiding the edges of the lenses exposed; those are the option if you have strong prescriptions.
Semi rim eyeglasses frames, also known as “grooved” frames, only cover half the prescription lenses. You will find nylon strings or liners running along the bottom of the prescription lenses to support the lenses, hence the semi rim frames are lighter than full rim frames. Of those frames, once we assemble the prescription glasses, we should instead cut grooves in to the prescription lenses edges. For that reason, the thicker lenses are needed for that semi rim eyeglass frames so we don’t chip and crack.
Rimless eyeglass, because the name implies, have no rim. The lenses are joined by the nose bridge and also the temples are joined for the lenses on the other ends. The rimless rim eyeglass will be the lightest eyewear. These are timeless since they are very simple, consequently look confident and versatile. But because of there is absolutely no rim around the lenses providing sufficient protection, they are least durable. Additional, the rimless eyeglass frame put quite high volume of force on the prescription lenses, therefore it is recommended that CR39 lenses should be avoided to utilize, as well as index lenses with better durability are recommended such as polycarbonate lenses.
