Using the continuing development of prescription glasses, increasingly more different designed eyeglass frames are becoming available. Normally, frames could be split into three different kinds – full rim, semi rim and rimless. A lot of people may question which frame type is best when they prepare to buy the prescription glasses at retailers or internet vendors. Actually, each frame type possesses its own features.
Full rim eyeglasses, also known as “hide-a-bevel” eyeglasses. They’re not only the most original eyeglasses and also the most popular and used designs. They encircle the prescription lenses completely; holds the lenses tightest, as well as intended for the thinnest prescription lenses. The full rim eyeglasses frames do an adequate job of avoiding the edges from the lenses exposed; those are the good choice for people who have strong prescriptions.
Semi rim eyeglasses frames, also referred to as “grooved” frames, only cover half the prescription lenses. You can find nylon strings or liners running over the bottom from the prescription lenses to keep the lenses, and so the semi rim frames are lighter than full rim frames. For these frames, if we assemble the prescription glasses, we must cut grooves to the prescription lenses edges. For that reason, the thicker lenses are needed for the semi rim eyeglass frames so we don’t chip and crack.
Rimless eyeglass, because name implies, haven’t any rim. The lenses are joined by the nose bridge and the temples are joined towards the lenses on the other ends. The rimless rim eyeglass include the lightest eyewear. They’re timeless since they are quite easy, thus making you look confident and versatile. But due to there is absolutely no rim regarding the lenses providing sufficient protection, they are least durable. Additional, the rimless eyeglass frame put high level of force on the prescription lenses, so it’s recommended that CR39 lenses needs to be avoided to utilize, and index lenses with better durability are suggested such as polycarbonate lenses.
