With all the continuing development of prescription glasses, a growing number of different designed eyeglass frames are becoming available. Normally, frames may be divided into three different types – full rim, semi rim and rimless. A lot of people may question which frame type is better when they prepare to get the prescription glasses at retail stores or online stores. Actually, each frame type features its own features.
Full rim eyeglasses, otherwise known as “hide-a-bevel” eyeglasses. They’re not only the most original eyeglasses and also the most popular and used designs. They encircle the prescription lenses completely; can take the lenses tightest, plus intended for the thinnest prescription lenses. The total rim eyeglasses frames do an adequate job of avoiding the edges in the lenses exposed; these are the good option if you have strong prescriptions.
Semi rim eyeglasses frames, also known as “grooved” frames, only cover half the prescription lenses. You can find nylon strings or liners running over the bottom from the prescription lenses to keep the lenses, and so the semi rim frames are lighter than full rim frames. For these frames, if we assemble the prescription glasses, we need to cut grooves in the prescription lenses edges. For that reason, the thicker lenses are needed for that semi rim eyeglass frames in order to not chip and crack.
Rimless eyeglass, since the name implies, have no rim. The lenses are joined by the nose bridge along with the temples are joined on the lenses on the other instrument ends. The rimless rim eyeglass are the lightest eyewear. They’re timeless as they are quite easy, consequently look confident and versatile. But on account of there is absolutely no rim surrounding the lenses providing sufficient protection, they’re least durable. Additional, the rimless eyeglass frame put high amount of force on the prescription lenses, so it will be recommended that CR39 lenses should be avoided to make use of, as well as index lenses with better durability are suggested like polycarbonate lenses.
