The ground-view progressive lenses are designed for people who enjoy the outdoors. These lenses are supposed to provide a natural feel to your vision and reduce lens distortion. Ground-view progressive lenses allow better vision through the sides and bottom of the lens, so they give you improved vision when driving, using computers and looking downwards.

With the popularity of televisions and computers, electromagnetic radiation has become the No.1 killer of vision. The invention of radiation protection glasses is even more popular, and its market is also widely optimistic.

The lens design of the computer protective glasses has no side effects on vision. Refined with a high-tech vacuum ion coating, it can block 0% electromagnetic waves. The lens contains anti-radiation substances and has the function of absorbing positive charges. It can absorb low-frequency radiation microwaves and avoid potential eye fever, headache, fatigue, dryness, and other adverse symptoms caused by electromagnetic wave radiation. The penetration and absorption function of different light can resist radiation and glare, and the user will obviously feel clear and natural vision after wearing it. At present, there are mainly anti-blue lenses and anti-fatigue lenses, which can effectively prevent blue light radiation and relieve eye fatigue.

Students can adapt to sitting still in a class by wearing bifocal glasses, but they can only wear glasses when they are in class or studying because of the inconvenience and even danger caused by the interruption of the glasses.

Why are titanium glasses expensive?

One reason is that the current titanium raw material cost is too high. The other reason is that the production of titanium frames is very complex. The production of titanium glasses requires special processing equipment, special welding technology, and electroplating technology, and many difficult and different processes, so it has a high production cost.

With the emergence of new titanium glasses production equipment and the improvement of production and processing technology in the industry, the price of titanium glasses will become lower and be available to a wider range of people.
