Each pair of glasses has its own size.
People began to shop for myopia glasses online, but because of lack of experience, many times the size of glasses is not appropriate. At this time they used to complain about the business or glasses. It is really because that they do not see the size of the frame. Just like our clothes and shoes, each qualified frame has its own size. Usually, the size will be marked on the inside of the temple or the bridge of the nose. The manufacturer will clearly mark the width of the frame, the width of the bridge of the nose, and the arm length of the glasses.
Is blue light blocking worth it?
There are two main problems with anti-blue glasses currently on the market. One is that the place to be prevented is not preventable, and the other is that people have color casts due to wrong protection and aggravate visual fatigue. Studies have shown that our eyes are the most intolerant of blue light in the 400-440 nanometer band. Therefore, current manufacturers mainly block blue light in this band when producing anti-blue glasses. However, the blue waveband of electronic products is between 450 nanometers and 490 nanometers, so most anti-blue glasses have little protection in this waveband. In addition, the blocking rate of anti-blue glasses is 20%~30% to achieve a good anti-blue light effect, but now the blocking rate of anti-blue glasses on the market has basically reached 80%~90%. All in all, these blocking blue light glasses cannot prevent the blue light in the 450-490 nanometer band, and their high blocking rate will also cause a color shift, which makes people more likely to have eye fatigue and headache.
In daily life, the intensity of blue light is low, not enough to cause damage to the fundus, so ordinary people do not need to wear anti-blue glasses unless they are working in extremely strong light conditions or working in special environments. To protect the eyes, it is more important for people to develop good eye habits. For example, wear a pair of suitable glasses and read insufficient light and at an appropriate distance. Avoid using electronic products for a long time. Take a break for 20 to 30 seconds every 20 to 30 minutes, and look at the distance regularly. If you have dry eyes while reading the electronic screen, remember to blink to 12 times per minute. It is best to wear sunglasses when outdoors.
Consider the elements of frame comfort.
What we need to know is that the frame exists first as a positioning device for the lens, and secondly as a beauty. The pupil is consistent with the optical center of the lens, so it should not be too high or too low. The horizontal direction is not skewed, and there is no one high and one low phenomenon. Bilateral symmetry is a standard for manufacturing enterprises. Non-mechanical symmetry is for the wearer. The frame should be adjusted according to the size of the wearer's face. The frame is not easy to slide down, and frequent slide is prone to the phenomenon that the pupil is too high and low to match the face.
The History of Clubmaster Glasses
Clubmaster glasses are a variation of the browline sunglasses made popular in the 1950s. The lenses of clubmaster glasses are typically held in place by a thin metal frame and are of a squared-off round shape.
Although many people believe that the Cubmaster glasses root back to the 1950s, the fact is that clubmaster glasses or clubmaster sunglasses as we know them didn’t come about until Bruce Willis wore a pair of Shuron Ronsirs browline glasses with tinted lenses on the TV series Moonlighting in the mid-1980s.
From that moment, browline glasses draw the public’s attention. By the 1960s, Ray-ban was a fairly large contender in the market and its owner Bausch & Lomb was one of the top manufacturers of browline-style eyeglasses. And then the Ray-ban launched the first browline sunglasses, called it clubmaster. Sales were enormous almost immediately and despite only coming out mid-80s, they still ranked as the third most popular style of sunglasses sold in the decade, next to Ray-ban’s Wayfarers and Aviators.
Then Ray-ban took every revision of the original 1947 Browline and began offering it as part of the clubmaster series. From bold brows to lightweight metal caps first introduced in the 1950s, the clubmaster offered a style that could fit elegantly on just about any face shape. After that, the clubmaster glasses have been popular for a long time.
The TR90 Spectacle Frame
TR90 frame is a kind of polymer material spectacle frame with memory, no chemical residue is released, and it meets European requirements for food-grade materials. It is currently an internationally popular ultra-light spectacle frame. TR90 frames have the characteristics of super toughness, impact resistance and abrasion resistance, and low friction coefficient, which can effectively prevent damage to the eyes and face caused by the breakage and friction of the frame during sports. Because of its specific molecular structure, it has good chemical resistance, is not easy to deform in high temperature environment, can withstand high temperature of 350 degrees in a short time, and is not easy to melt and burn. Moreover, the TR90 spectacle frame has a lubricating surface with a density of 1.14-1.15. It will float when placed in salt water. It is lighter than other plastic spectacle frames. It is about half the weight of the sheet frame and 85% of the nylon material. It can reduce the burden on the bridge of the nose and ears.
The role of the driving glasses
Good driving glasses can be very good to block high energy light, in the evening they can let more faint light enter into our eyes, really solving the problem of only blocking the light and not blocking the road. They have very good night vision function, and can better eliminate glare, better improve the vision of the driver. The driver can drive safely day and night. Strong sunlight improves visual clarity. They are special driving glasses and can brighten polarized light and improve driving safety. With unisex style, high-definition vision, comfort, and light. It can be used on rainy and foggy days and can be used by myopic people. It can effectively filter strong light and high beam lamps, and the long-term use makes you not tired. Both rainy and cloudy days can improve visual clarity. It can effectively prevent strong light, ultraviolet light, and glare is durable and can solve the problem.
Why are titanium glasses so expensive?
Strong and Durable. They are widely used in aerospace technology, jewelry, surgical instruments, and other fields. It is the most progressive material in the eyewear industry. Titanium is a very hard, lightweight metal that is proper for eyeglass frames. With good hardness, high strength, the glasses are not easy to deform. It is not easy to scratch and wear and has good corrosion resistance and plasticity. It has a high melting point, corrosion resistance, and hard electroplating. Titanium can be made into memory metal, which means it can bend and return to its original shape. Hinge is not easy to break, having rust resistance, impact resistance. When it's used in glasses, it fits the bill.If you've ever broken a frame, titanium is possible the best material for you.
