Choose the frame according to the face shape

Just like hairstyles and beards, frames should also be chosen according to your face shape. Of course, there is more than one frame for each face shape, and you can also prepare a few more pairs for yourself to match different styles. Try to avoid wearing spectacle frames that are too similar to the face shape, so as not to cause the lines of the face to be over-emphasized. Usually, the shape of the face is round, oval, square, rectangle, and heart-shaped. For example, if your face is square, you should choose glasses frames that are slightly wider than the shape of your face. This will make your face shape looks slightly slender. If the face is round, angular and square frames will help modify the lines of the face.

Convenience and timeliness.

The essential carrier of Mobile applications is the mobile terminals.

They are part of what the human body wears and can be used anytime, anywhere.

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.



Try to avoid wearing the following glasses.

If you need to wear glasses while driving, you'll need special glasses when driving at night, because common lenses reflect oncoming lights, which produces a faint glare. This will reduce your visibility. It's OK to wear contact lenses while driving. As you get older, your eyes become more sensitive to glare. Ordinary sunglasses or goggles are only suitable for wearing during the day, driving at night will seriously affect the vision (national standards stipulate that light transmittance of night driving glasses must be greater than75%). Although the all-weather driving glasses can weaken the strong lights, the vision darkens and affects road safety which does not meet the national standards for driving glasses at night. You should choose functional driving glasses that can block strong light, glare and increase the field of vision. This can effectively reduce the glare of the car lights but can filter out the extra harmful light. When worn at night, it can soften the strong lights and make the vision clearer. In this way, the safety of drivers is ensured, the fatigue of eyes is alleviated, and the radiation damage of harmful lights to glasses is prevented.


How about Ray-Ban clear frames?

Simple and clear lines, cool fashion, calm atmosphere, are all perfect interpretations of youth and fashion. Ray-ban frames have always been imitated, never surpassed, and a classic of classics. There are ray-ban plate spectacle frames usually using a black plate, lively and generous.



The working principle of driving glasses

The driving glasses are designed according to the polarized angle and radian of the lens and the principle of precision optics. It can only let the beneficial light pass through, and other light sources, like strong sunlight, car headlights, and other light sources are filtered, to eliminate the interference of external light, and avoid the appearance of eye-catching, dazzling, and other situations. That's basically how the driver glasses are designed.
