ELECTROSTATIC FILTERED EYEWEAR

摘要

An eyewear has a gasket (53) between the user and lenses (56) that electrostatically filterlthe air flow of particulate while still permitting a gentle flow of air to maintain comfort to the wearer of the eyewear, and prevent fogging on the lenses. The electret filter material (59) forms a perimeter around the eyes and lenses (56) to remove, small to large particulates, from microns to millimeters. The filters (51, 59) can be forme d with a choice of face contact gasket, baffles, coarse filters, and electret filter density.! Baffles or coarse filters over the electret filters are use d to protect the electret filter from damage from larger particles and transfe r heat to the airflow.
