And today we’ll offer some common things and tips on choosing a pair of anti-blue glasses. OK, let’s start!

What are anti-blue glasses?

In simple terms, harmful blue light refers to light with a relatively high energy between 400nm and 480nm. The blue light in this wavelength will increase the amount of toxin in the macular area of ​​the eye, which threatens our eyes. Anti-blue glasses, in short, are glasses that can block the damage of blue light to the eyes, and the blocking methods include coating radiation and molecular absorption filtration.

How to choose anti-blue glasses?

Price

When we choose anti-blue glasses, we should recognize that the price of anti-blue glasses is different, the lowest is only a dozen dollars, and the highest can reach thousands of dollars. Due to the difference in price, the actual anti-blue light effect also has a big difference. It is recommended that consumers should view their basic data information, and do not buy inferior products because  they are cheap.

Three Data

S1420

In general, the three most important data for anti-blue glasses lenses are anti-blue light rate, light transmittance, and chromatic aberration. Among them, the anti-blue light rate generally needs to be above 35%, the light transmittance needs to be maintained above 90%, and the color difference is as low as possible.

It should be noted that consumers should not excessively pursue the anti-blue light rate, and sacrifice the light transmittance and chromatic aberration. Such products tend to have a greater burden on the eyes, but they will be counterproductive. In addition, some users prefer to select some products with yellow lenses, but the anti-blue light rate of such products is not necessarily excellent, and the specific anti-blue-ray rate should be based on the product description.

Qualification Certificate

View the qualification certificate on some e-commerce websites, the price of anti-blue glasses is often very low, and the publicity page is also very long. However, there is no mention of the qualification certificate of the product. Therefore, in addition to viewing the basic data information, consumers should also pay more attention to the qualification test. Good anti-blue-ray glasses often have the qualification certificate of supervision by domestic and foreign authorities, while the low workshop products do not have such information. When we actually purchase, we can also check whether the product promotion page contains such qualification information. It is recommended to select products with qualified information and the quality is more secure.

Weight and Colors

In general, anti-blue glasses are mostly designed

in a light and thin process, and the overall weight is maintained at about 20 grams. Products that are too heavy (up to 40 grams) are less comfortable to wear, and consumers should pay attention when purchasing. In addition, some of the anti-blue glasses are designed with interchangeable frames, and have a variety of color frames, which can effectively meet the individual needs of users, and more worth buying.

How long to wear them?

In addition, anti-blue glasses should be used reasonably, and wearing them for a long time will cause damage to the visual resolution, especially those with high anti-blue light rate.

What else can protect from blue ray?

In addition to anti-Blu-ray glasses, we can also choose anti-Blu-ray mobile phone film, anti-Blu-ray computer film and other products, multi-pronged, to minimize harmful blue light damage, create a more comfortable eye experience.
