There are various ways to classify lenses, which can be classified according to their material, function, and surface treatment process.
Lenses can be mainly divided into glass lenses, resin lenses, PC lenses, etc. based on different materials.
Lenses can be divided into daily universal lenses, protective lenses, and multifocal lenses based on their usage functions.
(1) Daily universal lenses
Refers to optical lenses with general single focus and no special functions, which are the most widely used optical lenses.
(2) Protective lenses
Blue cut lenses are digital protective lenses that can effectively block high-energy and harmful blue light, retain beneficial blue light, and reduce eye damage caused by blue light. They are suitable for wearing when using LED digital display devices such as televisions, computers, IPAD, and mobile phones.
The damage of sunlight to the eyes is not only caused by ultraviolet radiation, but also by near-infrared radiation. Long term exposure to shortwave infrared radiation can cause significant damage to the eyes. Therefore, IR LENSES are urgently needed for eye protection, especially for young people, the elderly, those who enjoy traveling, and those who are outdoors.
In the era of continuous technological progress, the application of aspherical design reduces the edge aberration of the lenses to the lowest level, allowing them to have a wide field of view and meet the needs of customers; Aspheric lenses have a flatter base bend, lighter weight, and a more natural and aesthetically pleasing appearance.
It utilizes high vacuum biomimetic coating technology to imitate the honeycomb structure of bees, forming hundreds of honeycomb shaped hexagonal small lenses on the surface of the lens for full-time eye protection. The regular hexagonal structure of the honeycomb effectively filters out the ineffective diffuse light, making the light entering the eye effective parallel and concentric, removing the imaging of astigmatic lines, and making the object seen by the eye clearer.
