Resin lens care and use

Resin lens is a lens made of organic materials. The interior is a polymer chain structure, which is connected to form a three-dimensional network structure. The intermolecular structure is relatively relaxed, and there is a space for relative displacement between the molecular chains. The light transmittance is 84%-90%, the light transmittance is good, and the optical resin lens has strong impact resistance.

Resins can be divided into natural resins and synthetic resins. Natural resin is a hydrocarbon (hydrocarbon) secretion from a variety of plants, especially conifers. It is valued because of its special chemical structure and its use as a latex paint and adhesive. Since it is a mixture of various polymer compounds, its melting point is also different. There are many types of resins, which are widely used in light and heavy industries, and can often be seen in daily life, such as plastics, resin glasses and coatings. Resin lenses are lenses that are chemically synthesized with resin as raw materials and processed and polished.

1. The glasses should be placed in the mirror box when not wearing, and do not contact the outer curved surface (outer surface) of the lens with hard objects.
2. Rinse with tap water before wiping the lens. If there is oil stains, you can drop a little dishwashing detergent and then rinse with tap water, and then use a soft paper towel to dry the water.
3. Use a special fiber cloth to wipe the lens. If the fiber cloth is dirty, it can be washed and reused.
4. Film-coated resin sheets or cosmic sheets should be guarded against high temperature, do not wear glasses to take a hot bath, and do not wear glasses to take a sauna; do not put glasses in an unmanned car in summer; Blow directly onto the lens.
5. Although the surface of the resin lens has undergone special hardening treatment, it is still slightly inferior to glass, so avoid friction with hard objects. Try not to wear it when swimming at the beach.
