Problems solved by technology

If you are equipped with two glasses, you need to change them frequently during use, and you need to bring both glasses when you go out, which is not only troublesome to use but also inconvenient to carry

For example, wearing bifocal glasses can solve the problems of troublesome use and inconvenient carrying, but there is a problem with bifocal glasses: the bifocal lenses belong to the "vertigo zone" in the left and right areas outside the full viewing angle range, and the user sees the scene from this area , the scene will be severely deformed and cause dizziness

This causes the user who wears the bifocal glasses to only look at the scene in front of him, and when he needs to look at the surrounding scenery, he cannot turn his eyes to see from the "vertigo zone" of the bifocal lens, but can only turn his head at the same time

Due to this shortcoming, the limitations of the wearer are very large, especially when driving, the driver who wears bifocal glasses needs to turn his head to observe when frequently observing the front and side road conditions, which brings great inconvenience to driving. Potential safety hazards for driving
