knowledge that is related to eyeglasses. Although I bought my first pair of prescription eyeglasses in some unknown store, I got more knowledge from a famous online glasses store.
One of my friends recommended this online store after buying a pair of rimless eyeglasses from it, and she said that there was a lot to learn about picking eyeglasses. Then one day, I went to this online store to check, and I found useful information about the frames of eyeglasses. The detailed information on the frames of eyeglasses is like this. Nearly all eyeglasses –whether they are prescription glasses, prescription sunglasses, bifocal glasses, or fashion glasses—can be grouped into three categories according to the types of their frames. They are respectively: full-rim eyeglasses, semi-rim eyeglasses, and rimless eyeglasses. Just as every coin has its sides, these three kinds of frames have their advantages and disadvantages. Let’s begin with the full-rim eyeglasses which are also called “hide-a-bevel” frames. Generally speaking, this kind of frame is the earliest type of frame. What is more, it is also the most common frame type. Its advantages are very obvious, such as they can encircle the prescription lenses completely, hold the lenses most tightly, and are available for even the thinnest prescription lenses. What is worth mentioning is that this frame can be very convenient for those who are not very careful or who often have to take part in violent sports because, with the strong protection of the frames, the lenses are not that easy to break. On the other, this type of frame is not the most popular among young people. To them, eyeglasses are not only the tools to improve their eyesight but also an indication of their fashion. Then some of them choose the semi-rim type. These glasses have nylon strings or liners running along the bottom of the prescription lenses to hold the lenses, so the semi-rim eyeglass frames are much lighter than the full-rim eyeglass frames. However, this advantage is at the price of putting thicker lenses and taking good care in case it is broken. As to the rimless eyeglasses, they are the lightest and most convenient to carry, but the easiest to be broken.
Above is only some shallow knowledge on the frames of eyeglasses, to know more about it, you can go to glassespeople.com to have a check yourself. You can certainly gain a lot from their website. Maybe you are lucky enough to buy a cheap as well as fashionable one since they are on sale!
