Pure Titanium Glasses Frame Brand - Seiko
Seiko glasses, I believe, everyone has heard of this brand because Seiko glasses in the glasses industry are still relatively famous.Seiko is founded in 1881. It is one of the top ten pure titanium eyeglass brands in the world and enjoys a high reputation.So far, brand products have been involved in watches, optics, and other fields, and have done very wonderfully in different fields.Compared with similar products, its pure titanium spectacle frame is not only better than quality, but more in detail. Seiko's frame is divided into two categories: men and women.
There are business and professional styles.The two categories are divided into the full-frame and half-frame glasses frame. It can be seen that, in the style, Seiko glasses have a more clear, very specific positioning.For the common white-collar or company executives, the Seiko glasses frame is the most popular.
If you need reading glasses when using a computer, you may want to choose a lower reading glasses power. This is because most people view their screen from a greater distance from their eyes than when they are reading a book or a magazine.
However, if you need reading glasses for looking at something very close or very small, you may need a pair of stronger power glasses.
In most cases, when two reading glasses’ powers seem equally suitable, choose the glasses with the lower power. Picking reading glasses that are too string typically will cause more discomfort problems than reading glasses that are a little too weak.
Glasses are used as accessories.
Glasses can be used to outline your face. Most glasses have a positive effect on the temperament and image of the person, provided that the choice is proper. The function of the spectacle frame, in addition to its supporting the lens to form glasses to wear on the eyes of the people to play a support role, also has a beautiful, decorative role. Modern fashionable person emphasizes glasses should have harmony with the facial makeup and dress of person, reflecting social class, high learning, elegant fashion, and so on. When the spectacle frame is worn by people in the streets and alleyways, those who are not nearsighted begin to pay attention and feel that wearing a chic spectacle frame is a very fashionable behavior.
What are the features of TR90 glasses?
One of the best features of the TR-90 glasses is impact resistance. If you often drop glasses or accidentally sit on them, this material reduces the impact and the frames will quickly return to their original shape. They are flexible, and can easily show your face. Much lighter than other materials, the feather-light feeling makes them comfortable. Because the TR90 frame has high elasticity and is not easy to break, it has high strength and does not break. The material of TR90 is much more expensive than other PC, CP, and other materials, and the production process is strict, so the price of the TR90 frame is several times more expensive than other frame materials. Because TR90 material has strong wear resistance, chemical resistance, and solvent resistance, it is not easy to be burned. But TR90 material is the most widely used material in China at present, and its safety performance is the best one among all materials.
Take Frame material selection seriously.
When choosing a frame, try to choose a light frame. At present, the glass frame material is relatively light titanium, tungsten carbon, TR90, and so on. Now based on the plate spectacle frame, the new plate spectacle frame implements thin processing, so the whole spectacle frame has become light up. You can use rimless light glasses. Usually, the nose pad will leave an indentation, possibly because the glasses are too heavy. Changing some light glasses can improve the problem of indentation of the nose pads.
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.
