Abstract: Diving goggles with increased depth range includes a collapsible auxiliary air source chamber in fluid communication with the interior of the goggles. As the diver descends into the water depth, the outside pressure compresses the auxiliary chamber and forces some air out of that chamber and into the face chamber formed between the rigid portion of the goggles and the face of the diver. That additional compressed air when mixed with the compressed air inside the face chamber allows for relief of pressure from the user's eyes therefore avoiding eye strain and reduction in peripheral vision. The auxiliary chamber can be incorporated into the strap of the goggles and is attached to the rigid frame on both ends thereof. One or more collapsible leaf springs are placed inside the chamber to keep it open and in extended position while out of the water. Alternatively, the auxiliary chamber is made from a resilient material of such thickness as to ensure its extended shape once out of the water.
