With all the continuing development of prescription glasses, increasingly more different designed eyeglass frames are becoming available. Normally, frames may be separated into three different types – full rim, semi rim and rimless. Lots of people may ask about which frame type is better once they prepare to buy the prescription glasses at retail stores or websites. Actually, each frame type features its own features.
Full rim eyeglasses, also known as “hide-a-bevel” eyeglasses. Also, they are essentially the most original eyeglasses but also the most typical and used designs. They encircle the prescription lenses completely; can take the lenses tightest, as well as intended for the thinnest prescription lenses. The complete rim eyeglasses frames do an adequate job of avoiding the edges in the lenses exposed; they are the sensible choice for those who have strong prescriptions.
Semi rim eyeglasses frames, also called “grooved” frames, only cover half the prescription lenses. There are nylon strings or liners running down the bottom with the prescription lenses to support the lenses, so the semi rim frames are lighter than full rim frames. Of those frames, if we assemble the prescription glasses, we have to cut grooves in to the prescription lenses edges. For this reason, the thicker lenses are essential for your semi rim eyeglass frames so we don’t chip and crack.
Rimless eyeglass, because the name implies, have zero rim. The lenses are joined by the nose bridge as well as the temples are joined on the lenses alternatively ends. The rimless rim eyeglass include the lightest eyewear. They’re timeless as is also quite simple, consequently look confident and versatile. But due to there is no rim around the lenses providing sufficient protection, they may be least durable. Additional, the rimless eyeglass frame put extremely high volume of stress on the prescription lenses, so it’s recommended that CR39 lenses should be avoided to make use of, and high index lenses with better durability are suggested such as polycarbonate lenses.
