1. Eyeglasses with defogging means to be worn by a user, comprising:
- (a.) frame member comprising a non-conductive lens holding segment and an attachment means by which said lens holding segment is secured in a position so that the user looks through said lens holding segment,(b.) a left lens and a right lens held by said lens holding segment,(c.) power source which is not in direct physical contact with said frame member,(d.) power limitation means which is not in direct physical contact with said frame member and which is connected to said power source to automatically limit power usage,(e.) left conductive path leading from said power source to a conductive outer left contact point in contact with said left lens,(f.) bridge conductive path leading from a conductive inner left contact point in contact with said left lens to a conductive inner right contact point in contact with said right lens,(g.) right conductive path leading from a conductive outer right contact point in contact with said right lens to said power source, and(h.) lens conductive means for making said lenses capable of conducting an electric current,(i.) wherein said left conductive path, bridge conductive path, right conductive path, and lens conductive means together comprise a conductive path means by which electrical current generated by said power source may be conducted to said lenses and back to said power source to form an electric circuit, thereby heating said lenses.

Abstract
Eyeglasses worn in winter weather conditions are subject to fogging due to condensation of water vapor. A method of removing condensation from eyeglasses is provided. The method involves heating the lenses of the eyeglasses, by making the lenses a part of an electrical circuit. Electric current is supplied to the electric circuit from a power source external to the eyeglasses. The size and weight of the power source may be minimized by utilizing a timer or a power regulator. A smaller power source is also made possible by selectively heating the lenses, applying more power in the area of the lenses most likely to experience fogging.

14. Eyeglasses with defogging means to be worn by a user, comprising:
-
(a.) frame member comprising a lens holding segment and an attachment means by which said lens holding segment is secured in a position so that the user looks through said lens holding segment, (b.) a left lens and a right lens held by said lens holding segment, (c.) wherein said lens holding segment further comprises a conductive upper lens holding segment, a conductive lower lens holding segment, and a non-conductive holding segment securing means by which said upper lens holding segment is secured to said lower lens holding segment so that said right lens and said left lens are held between said upper lens holding segment and said lower lens holding segment, and (d.) power source which is not in direct physical contact with said frame member, (e.) power limitation means which is not in direct physical contact with said frame member and which is connected to said power source to automatically limit power usage, (f.) upper conductive path leading from said power source to said upper lens holding segment and from said upper lens holding segment to said right lens and to said left lens, (g.) lower conductive path leading from said right lens and said left lens to said lower lens holding segment and from said lower lens holding segment to said power source, and (h.) lens conductive means for making said lenses capable of conducting an electric current, (i.) wherein said upper conductive path, said lower conductive path, and said lens conductive means together comprise a conductive path means by which electrical current generated by said power source may be conducted to said lenses and back to said power source to form an electric circuit, thereby heating said lenses.
