Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spectacle lens capable of cleaning glass and plastic products such as spectacle lenses and the like, giving an anti-fogging effect, and providing an antistatic effect and an antibacterial effect. The antifogging detergent.

[0002]

2. Description of the Related Art Recently, transparent products such as spectacle lenses are made of glass or plastic, and many of them have a surface coated and subjected to a water-repellent treatment. And so on. For this reason, the conventional antifogging detergent is effective for a specific product, but is ineffective for another product.

[0003] Conventionally, the cleaning effect has been mainly pursued, and the antifogging effect, antistatic effect and antibacterial effect have not been sufficiently considered. In particular, recent eyeglass lenses have been subjected to a water-repellent treatment, so that the conventional technology cannot solve both anti-fog and cleaning.

Therefore, a need has arisen for an anti-fogging detergent which is compatible with any of the glass and plastic products such as lenses diversified as described above, is easy to wash, and has anti-fogging, anti-static and antibacterial effects. Have been.
