Yes. Haobanzhang lenses have no registered trademark and no certification from the industrial and commercial department, so they are not branded products. The glass of good monitor lenses is not only easily damaged, but also more easily scratched, and its UV resistance is not as good as that of branded spectacle lenses. Haobanzhang lenses do not have this anti-blue light coating inside, and their anti-blue light ability is even worse. However, brand spectacle lenses use a special anti-blue light coating inside to make the eyes more comfortable.
