With the development of prescription glasses, increasingly more different designed eyeglass frames have grown to be available. Normally, frames could be split into three different types – full rim, semi rim and rimless. Lots of people may question which frame type is way 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 are not only one of the most original eyeglasses but also the most frequent and used designs. They encircle the prescription lenses completely; holds the lenses tightest, as well as designed for the thinnest prescription lenses. The total rim eyeglasses frames do an adequate job of avoiding the perimeters in the lenses exposed; these are option if you have strong prescriptions.
Semi rim eyeglasses frames, also called “grooved” frames, only cover half the prescription lenses. You will find nylon strings or liners running down the bottom from the prescription lenses to keep the lenses, therefore the semi rim frames are lighter than full rim frames. For these frames, whenever we assemble the prescription glasses, we have to cut grooves in to the prescription lenses edges. That is why, the thicker lenses are expected to the semi rim eyeglass frames so we don’t chip and crack.
Rimless eyeglass, as the name implies, have no rim. The lenses are accompanied by the nose bridge and also the temples are joined for the lenses alternatively ends. The rimless rim eyeglass will be the lightest eyewear. They are timeless as they are quite easy, thus making you look confident and versatile. But on account of there is absolutely no rim surrounding the lenses providing sufficient protection, these are least durable. Additional, the rimless eyeglass frame put high quantity of stress on the prescription lenses, so it will be recommended that CR39 lenses should be avoided to use, and high index lenses with better durability are suggested such as polycarbonate lenses.
