Abstract: Novel petrolatums having silicone-like properties are disclosed. Silicone-free compositions containing the novel petrolatums also are disclosed.

Abstract: An improved adjustable rotary locking and unlocking device that utilizes a pushbutton to unlock teeth on a spring loaded hub drive that mesh within a swivel member. Once the hub drive and swivel member are disengaged by pressure on the pushbutton, the swivel member is freely moveable to any other position. Release of pressure on the pushbutton allows the teeth of the spring loaded hub to re-engage the teeth of the swivel member, thereby rigidly locking the device in place.

Abstract: Devices and methods for controlling myopia are provided. The devices and methods relate to the inventors discovery of the relationship between near work, the forces applied to the eye by the eyelids and myopia. The devices include a contact lens comprising a region that disperses force applied to the eye by an eyelid. The devices also include a device designed by measuring first wavefront aberrations of an eye before pre-near work and measuring second measured wavefront aberrations of the eye post-near work. The methods include a method for controlling myopia including identifying optical changes associated with near work and correcting the optical changes with an optical device.

Abstract: The invention provides a lens useful in correction of low and high order ocular wavefront aberrations order aberrations, and methods for designing and producing the lens, in which excessive variations in lens thickness are minimized.

Abstract: The invention provides methods for designing ophthalmic lenses, and lenses produced by this method, which lenses corrects both low order and high order wavefront aberrations of the lens wearer's eyes.

Abstract: A forward leaning stadium seat having a padded seat; a vertical support sleeve with an arm support device and quick release locking clasp to allow quick and easy up and down positioning of the arm support device and an adjustable hub to stop the forward and backward movement of the vertical support device at prescribed locations within a prescribed arc of travel.

Abstract: A portable forward leaning seating device to be used on a bleacher at sporting events to provide the user with superior support to that portion of his back which is most susceptible to fatigue and pain. The device consists of a padded seat (10) attached to a seat frame (12) which is securely attached to the bleacher by a spring loaded hook (42). The user sits on the padded seat (10) by facing the sporting event with the adjustable vertical support sleave (14) positioned between the user's thighs. The user rests his arms on the padded horizontal arm rests (16) which are positioned using the adjusting knob (32) and spring loaded tab (38) in such a way to provide comfortable support to the torso of the user in a forward leaning fashion. The lock clasp (20) serves to lock the vertical support armature (18) securely in place.
