With all the development of prescription glasses, more and more different designed eyeglass frames have grown to be available. Normally, frames might be divided into three different kinds – full rim, semi rim and rimless. A lot of people may question which frame type is way better after they prepare to purchase the prescription glasses at retailers or internet vendors. Actually, each frame type features its own features.
Full rim eyeglasses, also known as “hide-a-bevel” eyeglasses. They’re not only essentially the most original eyeglasses and also the most typical 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 an adequate job of avoiding the sides with the lenses exposed; they are the sensible choice if you have strong prescriptions.
Semi rim eyeglasses frames, also known as “grooved” frames, only cover half the prescription lenses. You’ll find nylon strings or liners running over the bottom in the prescription lenses to carry the lenses, so the semi rim frames are lighter than full rim frames. Of these frames, when we assemble the prescription glasses, we need to cut grooves into the prescription lenses edges. For that reason, the thicker lenses are expected for your semi rim eyeglass frames so we don’t chip and crack.
Rimless eyeglass, as the name implies, don’t have any rim. The lenses are joined by the nose bridge as well as the temples are joined to the lenses on the other half ends. The rimless rim eyeglass would be the lightest eyewear. They’re timeless as is also very simple, consequently look confident and versatile. But as a result of there is absolutely no rim around the lenses providing sufficient protection, they’re least durable. Additional, the rimless eyeglass frame put extremely high quantity of stress on the prescription lenses, so it is recommended that CR39 lenses must be avoided to use, and high index lenses with better durability are recommended like polycarbonate lenses.
