The arm length is an important part of the size of the glasses.

Spectacle frames are standard optical products. Just like people's clothes and shoes, they all have their own size. Usually, specs for the size of the glasses are on the inside of the temple, on the bridge of the nose, or on the label. In general, the frames of the glasses are marked with the width of the frames, the width of the bridge of the nose, and the length of the arm. For example, the inner side of the temple is labeled: 52口 18-135, indicating the lens width of 52mm, the width of the nose bridge of 18mm, and the arm length is 135mm.



How much does it cost to add the blue light filter to glasses?

Based on the difference in the impact of blue light of different bands on the human body, the blue light transmittance of each band of the product is separately required. For example, in the range of 415-445 nanometers, the light transmittance should be less than or equal to 80%, and above 445 nanometers, it should be greater than 80%. In this way, the anti-blue light products can be restricted, which can effectively shield the blue light that poses a health and safety risk to the human body, but also allows the blue light of the waveband that regulates the human body's circadian rhythm to be effectively transmitted.

Anti-blue glasses are not suitable for everyone. It is only suitable for people who use electronic products for a long time, not for people who are visually fatigued, and teenagers should not wear them for a long time. Furthermore, anti-blue glasses should not be regarded as a 'talisman' and use your eyes uncontrollably after wearing them. Therefore, when using electronic equipment, people must abide by the laws of nature, ensure the normal rest of the eyes, and maintain eye health.
