Together with the continuing development of prescription glasses, increasingly more different designed eyeglass frames have grown to be available. Normally, frames can be split into three different types – full rim, semi rim and rimless. Many people may inquire about which frame type is way better after they prepare to acquire the prescription glasses at retail stores or online stores. Actually, each frame type possesses its own features.
Full rim eyeglasses, otherwise known as “hide-a-bevel” eyeglasses. Also, they are essentially the most original eyeglasses and also the most frequent and used designs. They encircle the prescription lenses completely; can take the lenses tightest, and in addition designed for the thinnest prescription lenses. The complete rim eyeglasses frames do a good job of avoiding the sides of the lenses exposed; those are the option in case you have strong prescriptions.
Semi rim eyeglasses frames, also called “grooved” frames, only cover half the prescription lenses. There are nylon strings or liners running over the bottom in the prescription lenses to carry the lenses, and so the semi rim frames are lighter than full rim frames. Of these frames, if we assemble the prescription glasses, we have to cut grooves in the prescription lenses edges. For that reason, the thicker lenses are expected 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 as well as the temples are joined on the lenses on the other half ends. The rimless rim eyeglass are the lightest eyewear. They may be timeless because they are quite easy, consequently look confident and versatile. But because of there isn’t any rim regarding the lenses providing sufficient protection, they may be least durable. Additional, the rimless eyeglass frame put quite high amount of force on the prescription lenses, so it will be recommended that CR39 lenses should be avoided to utilize, and index lenses with better durability are recommended like polycarbonate lenses.
