Lemon glycerin swabstick helps to lubricate and soften tissue while the pleasant; refreshing lemon taste stimulates saliva flow. This solution soothes and refreshes dry mouths of patients with restricted oral intake.

Contact Lens Cleaners are for cleaning and maintenance of contact lenses. There are several different types of contact lens cleaners, and their uses are typically restricted to a specific type of contact lens. The most commonly used contact lens cleaner is the multi-purpose solution. They clean, disinfect and rinse all at once and can be used for contact lens storage. Hydrogen peroxide-based contact lens cleaners are also common. These cleaners disinfect the contact lens, removing bacteria and microorganisms that can adversely affect eye health. After using hydrogen peroxide-based contact lens cleaners, the lens must be rinsed prior to insertion or burning and irritation can occur. Ezymatic contact lens cleaners are a method of removing protein buildup on the surface of contact lenses.They are small tablets designed to dissolve in storage solution that the contact lens is soaked in overnight. Protein buildup will affect the performance and comfort of contact lenses, and if it is not removed at regular intervals, it can also affect eye health.

Lens Edging System computer numerical control machine system for edging lenses controls the rotation and displacement of a lens workpiece with respect to a edging tool in accordance with a lens shape stored in memory. The system continuously translates the lens workpiece axially across the surface of the wheel to uniformly distribute wear across the wheel surface, reducing the need to dress the edging tool. The system compares the lens size with predetermined dimensions and compenates for any difference by automatically adjusting the lens trajectory during the edging of subsequent lens workpieces, permitting the edging tool to wear down without appreciable errors in lens size. The system controls the edging tool speed, the lens rotation rate, the lens axial feed velocity and the grinding force between the lens workpiece and the wheel at each discrete point during the entire lens edging operation to optimize production while preventing overheating of the lens workpiece. The optimum values for these parameters are empirically determined in a preparatory programmed trial and error learning process of the invention.

Lens grooving device is a multipurpose apparatus for drilling, engraving and carving ophthalmic lenses. The apparatus comprises a base in which is mounted an electrical motor and a tool holder is connected to the shaft of the motor for detachably mounting a drilling, engraving or carving end mill above the upper surface of the base. A working support is also mounted on the upper surface of the base for maintaining and supporting the lenses in the various positions in which they must stand in order to be easily drilled, engraved or carved. The apparatus may advantageously be connected to a vacuum source for sucking out particles resulting from the drilling, carving or engraving operation through the small opening from which projects end mill and the upwardly expanding portion of the L-shaped tube. The apparatus may also comprise one or more lens guides adjustably mounted onto the guide holder for laterally guiding or retaining the lenses with respect to the end mill.
