Parashield’s anti-fog shield is not coated with a water-shedding coating, but the material itself has a function to absorb fine moisture droplets, which cause fog, and to evaporate them, thus the function will never be deteriorated and it is also possible to re-use the shield depending upon maintenance, such as sterile filtration.

A frame of Parashield is made from β-titanium, which is a semi-permanently usable material. Since this is a material where its specific gravity is light, and that has a spring property, it excels in fitting performance and is used for a material of high-grade eyeglasses. Further, since the surface is polished, it excels in hygiene at the time of re-use, as well.
