Here are the characteristics of resin lenses for you!
Optical properties of resin lens;
1.
The surface gloss and smoothness of resin lenses are by no means inferior to ordinary glass lenses.
2.
The refractive index of resin lens is lower than that of ordinary glass lens, so the resin lens with the same degree is thicker.
3.
The dispersion of resin lens is very similar to that of ordinary glass lens.
4.
The transmittance of resin lens is 92%, which is more than 2% higher than that of ordinary glass lens.
5.
The surface reflection of resin lens is lower than that of ordinary glass lens, and it is not so dazzling, because of its high transmittance and low refractive index.
6.
The bifocal lenses of resin lenses are made of a whole piece, unlike ordinary glass bifocal lenses, which are made by fusion. Therefore, the resin bifocal lens has no chromatic aberration.
7.
The optical properties of resin lenses are extremely stable and will not change at high temperature or low temperature.
Mechanical properties of resin lens;
1.
Resin lenses can be cast into lenses of various shapes, with high transparency and meeting optical requirements.
2.
Resin lenses are easier to frame than ordinary glass lenses.
3.
Resin lenses are easy to dye, and can be dyed into color lenses with different light transmittance as needed.
Physical properties of resin lenses;
1.
Resin lens is light and thin, and its weight is only half that of ordinary glass lens.
2.
Resin lenses have strong impact resistance.
3.
When the resin lens is broken by impact, there are few fragments, and the fragment area is large and blunt; Minimize eye and facial injuries.
4.
Although the resin lens has been used for a long time, the surface of the lens should not be fragile.
5.
Resin lenses have strong impact resistance to objects with high temperature and small volume. When these objects touch the resin lens, they will bounce off immediately. Unlike ordinary glass lenses, it is easy to cause dents and spots. Therefore, when welding or using grinding wheels, resin lenses can be used as a defense to prevent eyes from being injured by flying fire debris.
6.
Because the thermal conductivity of resin lens is low, its antifogging property is better than that of ordinary lens.
Chemical characteristics of resin lenses;
1.
Resin lenses can resist various chemicals and chemical solvents. At present, chemicals and chemical solvents used at home will hardly cause harm to resin lenses.
2.
Resin lenses have low thermal conductivity and high thermal resistance when heated. At a certain high temperature, it is not easy to produce bending and torsion deformation.
