What Is The Difference Between Polarized And Uv Protection Sunglasses?

What is the best lens material?

Early lenses were made of natural materials because they were easy to get. But natural materials have obvious drawbacks. According to records of the Qing Dynasty, Emperor Yongzheng wore crystal glasses given by the imperial court, which greatly improved the efficiency of reading documents. However, because of the cold nature, the crystal will make the temperature around the eyes low when wearing, and part of the crystal lens has color so that the light into the eyes becomes soft.


The classification is different.

Acetate frames can be divided into two kinds, one of which is the lens using acetate fiber processing of plate cutting. The other is the injection frame. It uses acetate fiber particles. Acrylic acid is a kind of unsaturated organic acid, which can be derived from a series of compounds to form a large class of acrylic products. Acrylic acid downstream products contain common acrylate and special acrylate. It has the characteristics of heat resistance, weather resistance, aging resistance, strong adhesion, water resistance, acid and alkali resistance, stickiness resistance, and environmental friendliness.



What are the benefits of the TR-90?

Impact resistance is more than 2 times of nylon material, in order to effectively prevent the damage to the eyes caused by impact in the movement. It has high-temperature resistance. It's very elastic, and it doesn't deform.The use of thermoplastic materials in these frames provides pretty strength due to their flexible characteristics. It is not easy to deform and change color, making it wear for a longer time. Having no release of chemical residues, it is in line with the European requirements for food-grade materials. The weight is less than half of the weight of the plate frame, 85% of nylon material, reducing the burden of nose bridge, ears, and making wearing more comfortable.


Difference Between Blue Light Glasses And Regular Glasses

Studies have shown that blue light is present in many light sources in our lives, especially on screens like cell phones, computers, and televisions. The main health effect of blue light sources is the damage to the eyes. Long-term exposure to blue light sources may cause lesions in the eyes. The harm of blue light to human health can be prevented by corresponding new technology products. Among them, the anti-blue lens is one of them. So how to distinguish between blue-light-blocking glasses and ordinary glasses?



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!


Pay attention to the wearing of myopia sunglasses when driving.

Some drivers are slightly myopic, usually driving without wearing a myopic mirror. There is no problem. But once you wear sunglasses, the problem comes: your eyes are more likely to tire and your vision will decline, just as your driving vision will be affected at night. Therefore, for the driver of slight myopia, there is no problem in usually driving, but if you want to wear sunglasses, you must be equipped with the lens of myopia degrees.

Do I need to buy anti-blue light glasses?

Nowadays, mobile phones and computers are used more and more frequently. Whether at work or in life, it is hard to imagine what life would be like without these electronic products. It is impossible to protect the eyes without using these products. Especially on mobile phones, the current LED screen technology has gradually replaced LCD screens, and the self-luminous characteristics have also caused serious fatigue to the eyes, and there is no need to say that blue light is harmful to the eyes. At present, the truly harmful blue light is the wavelength. In the blue light of 400 to 440 nanometers, this blue light easily causes eyesight fatigue. In the case of heavy use, try to reduce the damage to the eyes and protect the eyes, which is also the main reason for motivating consumers to buy anti-blue glasses.
