Abstract

Non fogging goggles are disclosed. An air scoop is provided at the bottom side of the goggles providing an air port with a cross sectional area of at least 1 square inch open in the front side of said frame for permitting air to enter the goggles. When the user is facing into a head wind, which may be self created, air is forced into the-goggles so as to cause a positive air pressure. A valve located at the top side of the goggle controls the amount of air passing through the goggles. In a preferred embodiment the valve comprises a spacer with four square ports 1/2 inch on a side, two ports on each side. One port on each side is covered with very light foam screen. The other two ports are unrestricted. A slider contains two 1/2 inch square ports which can be aligned by the wearer over the screened ports in the spacer or the unrestricted ports. The screened ports are utilized while in motion or during driving snow storms. The unrestricted ports are utilized while motionless on windless days while standing in lift lines.
