Below is a description of the characteristics of resin lenses!
Optical properties of resin lenses:
1.
Resin lenses have a glossy, smooth surface that is by no means inferior to that of glass lenses.
2.
The refractive index of resin lenses is lower than that of general glass lenses, so resin lenses of the same degree are thicker.
3.
The dispersion of resin lenses is very similar to that of glass lenses.
4.
The transmittance of resin lenses is 92%, which is more than 2% higher than that of glass lenses.
5.
The surface reflection of resin lens is lower than that of general glass lens, and it is also less harsh, which is due to its higher transmittance and lower refractive index.
6.
The bi-optical lens of resin lens is composed of the whole piece, not like the general glass bi-optical lens is made by fusion, so there is no chromatic aberration in resin bi-optical lens
7.
The optical property of resin lens is extremely stable, and will not be changed no matter in the high temperature or low temperature.
Mechanical properties of resin lenses:
1.
Resin lenses can be molded into a variety of shapes with high transparency and meet the optical requirements.
2.
Resin lenses are easier to frame than glass lenses.
3.
Resin lenses are very easy to dye, and can be dyed into various colored lenses with different light transmittance as needed.
Physical Properties of Resin Lenses:
1.
Resin lenses are light in texture, and their weight is only half of that of general glass lenses.
2.
The impact resistance of resin lenses is very strong.
3.
When resin lenses are shattered by impact, there are fewer fragments, and the broken area is large and blunt, which minimizes injuries to the eyes and face.
4.
The surface of resin lenses does not break easily even after long-term use.
5.
Resin lenses are highly resistant to high temperature and small objects, and when such objects hit resin lenses, they will bounce off immediately; they will not cause dents and spots as easily as ordinary glass lenses. Therefore, in the welding or use of grinding wheels, in order to prevent the eyes from being hurt by the spattering debris, resin lenses can be used as a defense.
6.
Because the thermal conductivity of resin lenses is low, their anti-fogging property is better than that of general lenses.
Chemical properties of resin lenses:
1.
Resin lenses have a wide range of resistance to chemicals and chemical solvents. The chemicals and solvents that are currently used in the home are virtually harmless to resin lenses.
2.
Resin lenses have a low thermal conductivity, and when heated, they are highly resistant to heat, and do not easily produce twisting and deformation under a certain limit of high temperature.
