Abstract: An eye shield having two layers of X-radiation protective material is disclosed. X-radiation initially encounters a metalized thin layer that permits the substantial transmission of accompanying visible light yet partially diffracts, reflects, and refracts the X-radiation to decrease the amount of X-radiation passing through this metalized layer. Beneath the metalized thin layer is a lead layer that allows the passage of limited amounts of visible light yet functions to absorb effectively X-radiation. In combination, these two layers protect the eyes of a wearer from harmful X-radiation while permitting the wearer limited forward vision.

Abstract: A method for setting an ophthalmic lens in a pair of goggles having a flat front transparent lamina for permitting vision and also having a shielding rim surrounding the lamina extending towards the face of the wearer for the abutment thereon is characterized by a lens secured inside the shielding rim adjacent the lamina. The ophthalmic lens has a flat plane adjacent the lamina separated therefrom by an air gap. A first silcone-base caulking is deposited between the periphery of the lens and the shielding rim up to a level substantially corresponding to the thickness of the air gap. This first caulking has a viscosity sufficiently sag-proof to maintain the caulking at the periphery of the gap during its hardening. A second caulking having a lower viscosity is deposited on the top of the first caulking up to a level corresponding to the top of the lens. The caulking is selected to be free of toxic and corrosive gas. The lens has a peripheral groove to improve the adherence of the second caulking.

Abstract: A pair of safety spectacles incorporates a brow-protecting bar member which is formed separately from the spectacle frame and is anchored thereto only at its ends, by means of the hinge pins attaching the temples to the frame. The frame and brow bar therefore have such freedom to flex back and forth with respect to each other as to provide a cushioning effect absorbing impact on the frame from the front after the brow bar engages the brow of the wearer, and this engagement is also made more comfortable by providing the brow bar with a brow-engaging flange of substantial height which extends the full length of the brow bar.

Abstract: An irreversible phototropic material consists of a plasticized matrix in which is suspended a phototropic transition metal salt and an additive which inhibits the production of haze in the phototropic material. Generally the additive is a substance which inhibits the reduction of the transition metal in the transition metal salt from a higher to a lower oxidation level. Suitable substances include chelating agents such as oxalic acid, ethylenediamine and EDTA, and oxidizing agents, such as chromium trioxide. The transition metal salt is preferably copper (II) chloride or a mixture of copper (II) chloride and bromide, while the matrix is preferably polyvinyl chloride or polyvinyl chloride/polyvinylidene chloride copolymer.These phototropic materials may be used in protective devices, such as goggles and windows, to protect objects or subjects against intense radiation.

Abstract: A locking means for a fixing band of diving mask which can fasten or release the fixing band as a fastening member to which one end of the fixing band is connected is inserted into or removed from a mask frame by one action. The locking means comprises two main portions: holders provided at the both sides of a mask frame integrally formed with a face fitting member of the diving mask, and fastening member formed in a taper shape, having three triangle pawls integrally formed with the fastening member. The three triangle pawls are so arranged as to become higher in order, so that the fastening member be gradually tightened owing to the triangle pawls as the fastening member is moved forwards.

Thickened regions can be provided above and below the slit(s) on the outward facing surface of the screen and the upper region can be thicker than the lower. An elasticated band can hold the screen over the wearer's eye region.

Abstract: A device for enabling a diver to determine his relationship to the true horizon in deep and murky waters or when physiological sensations are of little value is described. An attitude sensor, incorporating a series of mercury switches, usually at the back of the diver's helmet or head, is coupled to a series of light emitting diodes equally spaced around the periphery of the face plate of the diving mask or helmet so as to simulate the natural observation that the half space above the horizon is illuminated while the half space below the horizon is not.

Abstract: A pair of novelty eyeglasses includes a frame for supporting them on the wearer's head and a pair of transparent lenses. The frame includes a pair of support earpieces connected by hinges to the frames. Two light emitting diodes or LEDs are secured to the frame, one adjacent each lense and connected to a portable source of power, such as small batteries, mounted in one of the earpieces. A hinge switch, defined at one of the hinges connecting one of the earpieces to the frame, must be closed by moving the respective earpiece to the open position before the LEDs can be actuated. A manually actuatable switch is secured to the frame in series with the batteries and the light emitting diodes. The manually actuatable switch can be selectively closed by the user to energize the LEDs thereby creating a novel effect.
