subject: Be Careful With Choosing Eyeglasses Frames [print this page] Due to rapid development of eyeglasses industry, many kinds of eyeglasses frames are available both at local stores and on the internet. As for myself, the completely bendable memory frame is the best. If you need one, which type you will choose?
The development of prescription glasses has made more and more different designed eyeglass frames available. Normally, frames can be divided into three different types: full rim, semi rim and rimless.
Semi rim eyeglasses frames refer to "grooved" frames, only cover half the prescription lenses. There are nylon strings or liners running along the bottom of the prescription lenses to hold the lenses, so the semi rim frames are lighter than full rim frames. For these frames, when we assemble the prescription glasses, we need to cut grooves into the prescription lenses edges. For this reason, the thicker lenses are required for the semi rim eyeglass frames in order to not chip and crack.
Full rim eyeglasses are not only the most original eyeglasses but also the most common and used designs. They encircle the prescription lenses completely; can hold the lenses tightest, and also available for the thinnest prescription lenses. The full rim eyeglasses frames do a good job of avoiding the edges of the lenses exposed; they are the good choice for people who have strong prescriptions.
Rimless eyeglass, as the name implies, have no rim. The lenses are joined by the nose bridge and the temples are joined to the lenses on the other ends. The rimless rim eyeglasses are the lightest eyewear. They are timeless as they are very simple, and make you look confident and versatile. But due to there is no rim surrounding the lenses providing sufficient protection, they are least durable. Additional, the rimless eyeglass frame put very high amount of stress on the prescription lenses, so it is recommended that CR39 lenses should be avoided to use, and high index lenses with better durability are recommended such as polycarbonate lenses.
As described above, each frame type has its own features. In general, the completely bendable memory frame gains increasing popularity. Some people ask about which frame type is better when they intend to buy the prescription glasses at retail stores or online stores. Maybe answer is just the one you like.
