Clear glasses are in fashion.
Unlike those who used to wear plain glasses for the sake of a polite way, it is important for young men and women to wear glasses today to show their individuality, personality, and non-mainstream style. The clear eyeglass frame is classic, as the black frame. But relatively speaking, a clear white eyeglass frame has certain requirements to face shape, skin color, hairstyle. However, if you wear them properly and have enough confidence, those clear frames can be very stylish.
Benefits of Progressive Lenses
Progressive lenses are different from traditional reading glasses and bifocal glasses in that bifocal reading glasses have to constantly change the focal length, causing fatigue. And there is no clear dividing line between the two focal lengths. They are more comfortable, more beautiful. When you see far or see near, a pair of glasses can be done, so they become the best choice for old people little by little.
Progressive lenses allow multiple fields of view to be merged into a single lens with no discernible difference between the fields themselves. Degrees of the lens vary gradually from far to medium to your full reading. This is why progressive lenses are often regarded as no-line bifocals or trifocal points.
Should I wear blue light glasses when using electronic products?
However, it's not just at work that we need to consider wearing blue light glasses. We can still use blue-ray blocking glasses when we're reading a book on a tablet, watching hot new shows on Netflix, or playing games with friends. It is suggested that when you are in front of a digital device, you should wear blue light glasses to help your eyes.
Titanium frame machining is complicated.
The elastic modulus of titanium alloy is small, which is easy to produce large deformation, springback, distortion, and vibration in cutting, resulting in poor geometric shape and accuracy of the workpiece. As the surface roughness increases, the tool wear increases. The thermal conductivity of titanium alloy is poor and its thermal conductivity is small, 1/6 of that of 45 steel, so the high heat generated in processing cannot be effectively diffused. It is even harder to use titanium to make glasses. The frames are very thin and a lot of fine work is demanded. It's definitely a challenge for titanium, which is pretty difficult to work with. In addition, titanium alloy frames involve titanium alloy welding technology, which is more difficult.
Recommended Glasses for Heart Shaped Face
Wayfarers frames: to balance out a wider forehead is by finding frames that have wide, prominent endpoints that extend out past your temples. This can draw the gaze up and away from your cheekbones, making your eyes the focal point. So, the wayfarers frames are recommended.

Bifocal vs Varifocal Glasses: What Are Their Differences?
The above part has introduced some basic information about bifocal glasses and varifocal glasses. So, what are their differences?
- Bifocal glasses have two different prescriptions in one lens, while varifocal glasses have three different prescriptions in one lens.
- There is a distinct line between different prescriptions in bifocal glasses. Varifocal glasses allow getting through other prescriptions smoothly.
- Varifocals can give you a vision at any distance.
- Bifocal glasses are more cost-effective than varifocal glasses.
However, they also have some similarities. Both glasses can be used to correct presbyopia vision. So, when you choose glasses, you can decide to choose bifocal glasses or varifocal glasses based on your needs. If you want to get a pair of corrective glasses online, Koalaeye Optical is recommended. It is an online glasses store and provides all kinds of eyeglasses, sunglasses and frames.

What are nose pads?
Nose pads include stipule stalk, stipule boxes, and stipules. The stipules are in direct contact with the nose and play a role in supporting and stabilizing the frame. Certain molded plastic frames may not have stipules and stipule boxes, and the stipules are connected to the mirror ring.
In fact, when designing different materials and different styles, the designer will judge whether nose pads are needed according to the comfort and aesthetics of the glasses. Generally, metal frames are equipped with nose pads, and the nose pads are movable in order to adapt to various nose shapes. Metal frames with nose pads can prevent some people's skin from being allergic to metal. On the other hand, metal looks more rigid and business, and adding nose pads is more beautiful and comfortable. Most glasses without nose pads are sheet-framed glasses. The sheet material is relatively light and non-allergenic. In terms of aesthetics and comfort, no nose pads are more suitable.
