Useful Suggestions for installing Half-rim Eyeglass Frames
According to the frame structure, these are three fundamental forms of frames. Most customers know that is full-rim, half-rim, or rimless glasses frames. Full-rim eyeglasses as the most traditional form are losing a certain amount of popularity. More and more people turn to semi-rimless and rimless models.
Half-rim, or semi-rim, these eyeglasses have the upper part of the frame, while the bottom part is rimless, so sometimes it is also called half-rimless eyeglasses. The lenses are fixed by a filament, which is a string serving as part of the frame below the metal half-rim. However, the string is invisible, looks like a fishing line. It is put in the required groove to help to hold the lenses in the frame, so, you are feeling that just see the half part of the rim.
The office wearer always likes rimless frames, but the parents just would like to buy the safer full-rim frames for kids. Half-rim frames are young people’s favorite, due to could show their own fashion elements while wearing it, for example, the rectangular rim is matching for the mature and sedate gentleman, the oval rim is the elegant lady’s perfect choice, and the flying wing-like rim is designed for fashion peoples. My multiple friends told me that I should visit this website. – glassespeople.com, actually, provides a great variety of discount half-rim glasses with highlight designs which are my favorite.
However, with only a half-frame wrapping partially the lenses, it is harder for semi rim eyeglasses to be durable. The reason is obvious that such a tiny frame can not hold the lenses stably. This is similar to the rimless and semi-rim designs used in prescription eyeglasses. Those products are quite delicate and easier to be broken. Eyeglasses made with this design can not bypass this limitation or shortcoming. The upside of these eyeglass frames is that they bring a modern, attractive look. Using only a half-frame also helps reduce the overall weight.
On the other hand, as the strength for holding the whole pair of rimless eyeglasses comes from the lens itself, we need to strongest lenses such as polycarbonate and other high index lenses. But for semi-rimless eyeglasses, it is not a problem to resin lenses like CR-39, as the top portion of the frame and the bottom nylon string can hold the lenses tightly through the groove the edge of lenses. However, it also has some disadvantages. If you have a very low prescription, the lenses corresponding to your prescription entered to have a much thinner edge to put the required groove in, it will be too difficult to install for your prescription eyeglasses.
