About frameless glasses

June 11th, 2015

Frameless eyeglasses provide a minimalistic look in eyewear, making the glasses nearly invisible on the face. Lenses are joined together by the nose bridge only, attached directly to the inside of each lens with tiny screws. Hinges are connected in the same way to the outer edges, supporting the earpieces or arms. Plastic lenses are commonly used in frameless eyeglasses, also available as sunglasses.

Because they lack frames, frameless glasses can sustain damage more easily than other eyeglasses designs. This is nominally a result of the material used to produce the lenses. Although relatively durable inside of frames, CR-39 lacks impact resistance and cannot absorb the wear and tear of constant stress to the lenses caused by putting on, wearing, and removing glasses. For this reason, the implementation of polycarbonate, in addition to making frameless glasses even lighter, reduces the glasses’ fragility as polycarbonate can endure a great amount of stress and is highly impact resistant. To ensure both the longevity of the glasses and as a safety precaution, more optical labs are refusing to mount CR-39 lenses in rimless frames.

Frameless eyeglasses are easily to be damaged. Common accidents are glasses being stepped on, sat on and lenses getting scratched. So your eyeglasses provider probably included a hard case with your frameless glasses. Hard cases give the best protection. You can throw them in your purse or backpack and know your eyeglasses will be safe. Moreover, please do not keep your eyeglasses lenses down, it will get scratches easily.

There are a few important considerations when shopping for frameless eyeglasses. First, lens shape is most often rectangular or round with variants. If you buy frameless glasses online, most retailers offer guidelines for choosing a lens shape that will work well with your facial structure, including the ability to determine the best lens height and width for your face. You will also need to take a measurement to determine the best nose bridge width, and another for the earpiece length. Armed with these guidelines, you can sort eyeglasses by lens size, then look for the right bridge and arm length.

The upside and downside or wireless glasses

According to the basic frame structure, all of the currently available eyeglasses can be grouped into full-frame, semi-rimless and rimless types. While full-frame glasses are the most traditional, the other two categories are more modern. Yet one point is true that all of these three types exist in parallel and support different demands from customers. In this article, the focus in wireless glasses, another name of frameless or rimless glasses. Like semi-rimless glasses, three-piece rimless eyeglasses do not completely encircle the lenses. In some cases, these two styles are considered as variations that differ from regular glasses. In fact, it is more precise to say that rimless spectacles do not have any frame around the lenses. Their bridge and temples are mounted directly onto the lenses. The connection part is usually some tiny screws. Currently there is a rare variation that is attached to a piercing at the bridge of the wearer’s nose.

The current situation of the eyewear market is that wireless glasses develop in parallel with other two categories. It is easy to hear some people praising rimless spectacles, and meanwhile some others complaining these products. This actually reflects a fact that this primary style has both advantages and disadvantages. They have been around for many years due to the upside. And the incapability of replacing other two types is due to the downside. Recognizing both of these two aspects would help us get a comprehensive evaluation while considering rimless spectacles.

In many people’s mind, rimless eyeglasses will bring a more attractive look than semi-rimless and full-frame ones. The reason is that wireless glasses have nearly no visible frame, thus the whole face can be visible. Prescription glasses use crystal clear lenses so that no part of the front face will be shielded. For people who are confident with personal facial features, this effect granted by wireless glasses is really valuable. Yet what is the downside of these products? Since there is no frame holding the lenses, frameless eyewear is quite delicate and is easier to broken. They require particularly careful insertion and removal as well as daily care.

A comparison between frameless eyeglasses and transparent eyeglasses

June 7th, 2010

Eyeglasses for vision correction are widely needed by a large proportion of the world’s population. It is the manufacturers’ responsibility to meet the diversity of customers’ needs. People in different countries or with varying occupations will likely have colorful tastes about eyewear style. The good news is that the current prescription eyewear market is able to provide a wide variety of frame styles arranged in numerous models. Frameless eyeglasses and transparent eyeglasses are two of the popular styles in recent years. Some people may not understand the title of this article. Is it feasible to make a comparison between these two eyewear styles? Well, there is actually a close link between them.

Let’s first make a discussion of a special trend in the eyewear industry. Prescription eyeglasses for vision aid were originally ugly ones at the early stage. This is why there were many people who refused to wear them at that time. The reason is likely that eyewear manufacturers in those early days hardly paid attention to frame design and appearance. Most of their attention was paid to the guarantee of lens functionality. Currently, the eyewear market is completely different in this sense. Frame style and fashion have been an inseparable part of a pair of prescription eyeglasses, exemplified by the colorful, attractive eyeglass models, among which there are frameless eyeglasses and transparent eyeglasses. Compared with full-frame eyeglasses, a rimless pair could enable wearers to show a maximum part of their facial beauty. The reason is obvious that there is nearly no frame covering the front face. Transparent prescription eyeglasses are supposed to achieve a similar effect. Even if a whole frame is present on the nose, it is transparent and the facial features behind it are generally visible.

Except for the similarity between frameless eyeglasses and transparent glasses, there are also possible differences between them. Rimless glasses can feel free to take use of colorful temples, which will be attached directly onto the lenses rather than onto a frame. But transparent glasses usually take use of transparent plastic temples.
