Abstract: An eyeglass case for protectively housing eyeglasses. At least one wall of the case is formed with an inflatable chamber. The chamber may be selectively inflated. The eyeglass case, in its inflated state, protects the eyeglasses to a maximum degree and the case floats. The case may be inflated by blowing into a simple blowhole opening, with an integrated pneumatic pump, or with a gas cartridge that allows repeated inflation. The case may be formed with a soft inner pouch which is surrounded with an inflatable outer pouch, or it may be formed with a rigid bottom shell and a soft, inflatable top in the form of a lid.
