The difference between anti-blue light lens and ordinary lens

1. Different functions: Anti-blue light glasses are glasses that can prevent blue light from irritating the eyes. Special anti-blue light glasses can effectively isolate ultraviolet rays and radiation and filter blue light. They are suitable for use when watching computers or TVs and mobile phones. Ordinary eyes are suitable for going out, doing homework and reading.

2. The effect is different: Anti-blue light has no effect on preventing myopia, but has a certain effect on preventing eye fatigue. But blue light can inhibit the secretion of melatonin, which is an important hormone that affects sleep. It can promote sleep and regulate jet lag. Wearing blue light glasses before going to bed will not affect sleep quality, while ordinary glasses will.

3. Different prices: Anti-blue light glasses are more expensive than ordinary glasses.

4. The color of the lens is different: the color of the anti-blue light lens is light blue or light yellow, while the ordinary lens is transparent and has no color.

How to identify anti-blue light glasses

1. Look at the packaging to check the anti-counterfeiting: regular brands of anti-blue light glasses lenses have relevant anti-counterfeiting codes on the packaging, which can be checked by users. You can check whether the product is legitimate according to the anti-counterfeiting codes.

2. Check the fog display anti-counterfeiting code: the lens itself has a fog display anti-counterfeiting code, which can be displayed by breathing on the lens, and you can check the authenticity by logging on to the official website of the lens brand.

3. Irradiation with a blue light pen: Use a blue light pen to irradiate the lens. For lenses without anti-blue light function, the blue light basically completely penetrates the lens. For anti-blue light lenses, under the irradiation of blue light, most of the blue light is blocked by the lens.
