The spirit behind celluloid glasses

Because celluloid material is flammable, it cannot be mechanized and basically needs to be created by hand, which forms a unique set of handcraft modes of Japanese crafters. Today, there are only a few celluloid factories in Japan, and the unique manual process and production are relatively small. This makes celluloid handmade glasses even rarer and more valuable. Celluloid was originally a very common and cheap material, even with a certain degree of danger, but because of the unique craftsmanship of skilled craftsmen, its performance was brought to the extreme, so that celluloid glasses became unique and sought after by some people. The material of the frame is an important factor that determines the comfort of the glasses. While ensuring comfort, people hope that the glasses can have a decorative effect and play a role in clothing matching in different scenes.


Types of Bifocal Lenses

Executive: in this type of bifocal lens, the lens is separated completely from each other and the upper part of the lens and the lower part of the lens are divided into two equal halves. There is a distinction line and it is visible.

Progressive lens: these types of lenses are more popular than the other kind of lenses. There is no line in the progressive lens. There is a slow transition of the power from the upper part of the lens to the lower part of the lens.

Progressive multifocal lenses: a progressive multifocal lens gradually changes power from the upper part of the lens to the lower part of the lens and gives a smooth transition between the two different types of bifocal lenses. There is no distinction line in the lens. They are popular because they provide better adaption, comfort, and clarity than the other lenses.



Blue light blocking glasses to protect eye health

The protective effect of blue light blocking lenses requires professional equipment, such as spectrometers, to detect the transmittance in the blue wavelength band, and consumers cannot detect them on their own. For anti-blue glasses, if you consider buying, it is recommended that consumers choose to buy from a professional optical shop.

In the digital society, people are increasingly inseparable from electronic screens. In order to protect eye health, many people fall into the misunderstanding that anti-blue glasses must be worn for a long time. In this regard, wearing anti-blue glasses also needs to vary from person to person and from time to time. If you watch the screen for a short period of time every day, and there are intervals, pay attention to rest, you do not need to wear anti-blue glasses. For people who frequently and continuously perform high-intensity visual tasks, it is recommended to wear anti-blue light glasses due to the possible medium and long-term cumulative effect of blue light.

Consumers must distinguish the specific situation when buying blue light blocking glasses, and then choose the best blue light blocking glasses that suit them. The right choice of fashionable and suitable anti-blue glasses can give your eyes full relaxation and comprehensive protection!


Why Are My Progressive Lenses Blurry?

Progressive lenses are optical lenses designed for simultaneous correction of far, medium and near. Progressive lenses use polishing technology to achieve a gradual transition between the two focal lengths. With progressive lenses, people do not have to switch their glasses for different purposes.

However, with the usage of progressive lenses, there are some problems of progressive voices. One of the most commonly reported side effects of progressive lenses is blurry or fuzzy peripheral vision. The blurriness is usually most noticeable through the lower portion of the lens and to the left and right of near and immediate zones.



Who are TR90 glasses for?

Both plate glasses and TR90 frames have their own characteristics and benefits. The plate glasses deduce fashion and are easier to match clothes. It integrates the plate and the texture of the metal, which can better reflect the personality and style. TR90 frames have been widely used in many optical fields like sunglasses, 3D glasses, polarized glasses, radiation-resistant glasses, etc.TR90 frame is so popular in men and women because of its variability. TR90 frame can be perfectly combined with other metals. The neat lines and bright colors bring fresh and energetic outdoor energy to the dull city. The light texture, about half lighter than the plate frame, can reduce the burden on the bridge of the nose, ears, and facial skin, which is very suitable for teenagers who just wear glasses.


Wear blue light glasses before bed.

Because blue light can have a huge impact on your sleep cycle, these glasses are pretty important before bed. So, putting on blue light glasses before you go to bed can help increase melatonin, which in turn helps you get a good night's sleep. Sleep glasses display a wider range of blue light, which naturally helps you sleep better and triples melatonin production. They have a slight lens color because they target a wider range of light, but are best for sleeping. In addition to sleep glasses, there are nearly transparent optical glasses that filter out blue light levels to help treat digital eye strain, which is made up of headaches, blurred vision, and eye strain.



Does it take time to adjust to progressive lenses?

How long should it take to get used to progressive lenses? I have never worn glasses before.Progressive lenses were developed to allow easy switching between near and far views. Progressive glasses are divided into four parts. The upper part is the far-light region. The lower part is the near-light region, and the middle part is a variable light region. From top to bottom, if the hyperopia film is gradually increased and the myopia film is gradually decreased. The middle variable area is on both sides of the astigmatism area. Because of the prism effect, when you see things, through this area, the object will be blurred, and the eyes will feel uncomfortable. If the height of the frame itself is very small, the transition zone of progressive multi-focus is very narrow, and the eyes may not adapt to the sunglasses. The current design of progressive lenses is still not mature. Imported brands are relatively stable but expensive, and domestic brands are not mature in design. For various reasons, progressive glasses may be difficult to adapt to wearing.
