Abstract
Abstract The device is in the form of a pair of specially designed glasses, goggles or an eye mask sealingly engaging the wearer's head. In each case, a frame includes a front support bearing one or more transparent, preferably prescription-ground lenses or eye shields, and a pair of side supports connected thereto. Components are connected to or built into the frame to allow free passage of air to the eyes while blocking contaminant-bearing liquids and solids. Thus, in one embodiment, eyeglasses are fitted with two sets of triangular preferably air permeable flexible sheets. One set of sheets depends from the side supports and is connected to the sides of the front support, with the other pair is connected to the side and front supports above the latter, being connected at its rear end to slides in the top of side support channels to permit easy folding of the glasses. In two other embodiments, goggles and eye masks bear air vents fitted with liquid and solid-blocking filters. Such filters may be replaced and may be sandwiched between screens within outer vented boxes.
