With the development of prescription glasses, more and more different designed eyeglass frames are becoming available. Normally, frames can be divided into three differing types – full rim, semi rim and rimless. Lots of people may inquire about which frame type is way better whenever they prepare to buy the prescription glasses at stores or internet vendors. Actually, each frame type has its own features.
Full rim eyeglasses, also known as “hide-a-bevel” eyeglasses. They are not only essentially the most original eyeglasses but also the most typical and used designs. They encircle the prescription lenses completely; can hold the lenses tightest, as well as intended for the thinnest prescription lenses. The full rim eyeglasses frames do an adequate job of avoiding the perimeters from the lenses exposed; those are the good choice for people who have strong prescriptions.
Semi rim eyeglasses frames, often known as “grooved” frames, only cover half the prescription lenses. You’ll find nylon strings or liners running down the bottom of the prescription lenses to carry the lenses, so the semi rim frames are lighter than full rim frames. Of these frames, whenever we assemble the prescription glasses, we have to cut grooves into the prescription lenses edges. That is why, the thicker lenses are essential for that semi rim eyeglass frames so we don’t chip and crack.
Rimless eyeglass, because the name implies, haven’t any rim. The lenses are accompanied by the nose bridge along with the temples are joined towards the lenses alternatively ends. The rimless rim eyeglass are the lightest eyewear. These are timeless since they are quite easy, thus making you look confident and versatile. But as a result of there’s no rim around the lenses providing sufficient protection, they are least durable. Additional, the rimless eyeglass frame put very high quantity of stress on the prescription lenses, so it is recommended that CR39 lenses should be avoided to use, as well as index lenses with better durability are suggested for example polycarbonate lenses.
