With the progression of prescription glasses, more and more different designed eyeglass frames have become available. Normally, frames can be split up into three different kinds – full rim, semi rim and rimless. Lots of people may question which frame type is better when they prepare to purchase 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. Also, they are the most original eyeglasses but the most common and used designs. They encircle the prescription lenses completely; holds the lenses tightest, and also readily available for the thinnest prescription lenses. The entire rim eyeglasses frames do a good job of avoiding the edges of the lenses exposed; they are the option for those who 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 along the bottom in the prescription lenses to carry the lenses, and so the semi rim frames are lighter than full rim frames. Because of these frames, when we assemble the prescription glasses, we must cut grooves into the prescription lenses edges. For this reason, the thicker lenses are expected for your 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 as well as the temples are joined towards the lenses on the other half ends. The rimless rim eyeglass include the lightest eyewear. They’re timeless because they are very easy, therefore making you look confident and versatile. But because of there isn’t any rim regarding the lenses providing sufficient protection, these are least durable. Additional, the rimless eyeglass frame put high level of stress on the prescription lenses, so it will be recommended that CR39 lenses must be avoided to make use of, and index lenses with better durability are suggested for example polycarbonate lenses.
