Alloy glasses frame
Spectacle frames made of the alloy have relatively high hardness, are more resistant to friction, are not easy to fade, have a better texture, and are made of more styles, which are essential for fashionistas.
What is blue light?
To prevent blue light, we must first understand what blue light is. The visible light with a wavelength range of 400-500 nanometers is called blue light. The light sources used in daily LED lighting and display products, including mobile phones, flat panels, and TVs, are mostly LED light sources excited by blue light. However, not all blue light is harmful to the human body. The human eye has an extremely low tolerance to blue light radiation in the 400-440 nanometer range. When the light intensity enters this threshold, photochemical damage is likely to occur. However, blue light radiation in the range of 459-490 nanometers is essential for regulating the human body's circadian rhythm and can affect the secretion of human melatonin, which in turn has an impact on the body's biological clock, alertness, and mood.
Scientifically effective anti-blue light lenses must not only block harmful blue light but also cannot filter beneficial blue light. Most of the ineffective anti-blue light products on the market currently have two types of problems. One is that there is almost no protective effect on the blue light in the vulnerable zone of the human eye. The other is excessive protection, shielding the blue light spectrum in the beneficial band so that the blue light that is beneficial for physiological adjustment cannot enter the human eye. At the same time, the color of the lens is yellow, which is prone to color shift, aggravating visual fatigue, and even inducing the risk of myopia.
The superior properties of titanium glasses
They are light, around 40% of stainless steel. The hardness is high, about twice that of stainless steel and common steel, twice that of iron, and six times that of aluminum. In a world of ultra-low temperatures, titanium becomes harder and more superconductive, while steel becomes weaker and less capable. They have corrosion resistance, with no rust. Titanium does not rust in the sea for five years, while steel corrodes and deteriorates in seawater. The thermal conductivity of titanium is about the same as that of stainless steel. They are non-allergic materials. Titanium is a harmless material to the human body. More because it does not have an allergic reaction to the human body, it is one of the few metal materials used in medical science.
Why My New Glasses Give Me a Headache?
The new glasses make me dizzy or headaches. You may have these symptoms when getting a new pair of glasses. Why do the new glasses give me a headache?

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.

Disadvantages of glasses
They can distort vision, especially at the edges of lenses if you have strong prescriptions or astigmatism. Some people have trouble adjusting to progressive lenses. These lenses fog up and splash in the rain. Due to the limitation of the frame itself and the effect of the prism effect in the peripheral part of the glasses, the wearer can see a relatively narrow field of vision.
