Do blue light glasses actually block blue light?

Anti-blue light glasses are still popular on the market. This kind of glasses is said to be 'anti-radiation and anti-blue light', but this kind of hot-selling anti-blue glasses has many problems. At present, such anti-blue glasses mainly block or absorb blue light through special materials, but there are two misunderstandings in its blue light protection. One is that the protection is not preventable, and the other is that the color cast caused by the wrong protection makes visual fatigue aggravated. Studies have shown that our eyes are the most intolerant of blue light in the 400nm to 440nm band. Therefore, current manufacturers mainly block blue light in this band when producing anti-blue glasses. But the electronic products that we often come into contact with nowadays produce blue light between 450 nanometers and 490 nanometers, and anti-blue glasses have almost no protection in this wavelength. Generally speaking, the blocking rate of anti-blue glasses is 20% to 30%, but now the blocking rate of anti-blue glasses on the market basically reaches 80% to 90%. This high blocking rate can also easily cause a color shift. , It is easier to make the eyes tired.



A saddle bridge is a type of bridge.

The bridge of the nose can make your nose look slimmer. There are two main types. The keyhole distributes the weight of the glasses to one side of the nose rather than the top. It's a good choice for those with a broad nose. The Keyhole Bridge is old-fashioned in the classic style, like a Keyhole. This design creates a small gap in the top part to give the impression of space, thus making your nose look smaller. Saddle bridge is a more modern style and usually goes around your nose with almost no gaps at the top. This close contact will make your nose look tighter.

The rough side is designed to give you more friction when you touch it with your finger, so you can use it more easily, and you can clean it more.



Anti-fouling Coating

The lens coated with anti-reflection film is pretty prone to stain, and the stain will affect the transmittance of the lens. Microscopically, the anti-reflection film shows a porous structure, therefore, the oil is very easy to soak in it. The solution is to coat a layer of anti-fouling film with anti-oil performance on anti-reflection film. The film is very thin and will not change the optical performance of the anti-fouling film. The material is mainly fluoride. There are two processes, one is the immersion method, one is the vacuum coating method (the most commonly used).
