Abstract

Disclosed is an anti-fogging method including forming fine particles by pulverizing transparent crystals into a size of lO nm or less, manufacturing a crystal suspension by mixing the pulverized fine particles with washing water, introducing the crystal suspension into the pores by dipping an object including the glass, plastic or lens into the heated crystal suspension and then moving the object up and down or left and right, and taking the object out of the suspension to dry off the object.
