Abstract: The present invention is directed to a vial including a stack of test sensors, wherein the vial includes a vial body and a vial cap and a seal. In one embodiment of the present invention, the seal includes an annular ledge, a flange attached to the annular ledge, a hinge, also referred to as an annular line of weakness, and a skirt. In one embodiment of the present invention, the annular line of weakness is positioned between the skirt and the flange such that the skirt folds outward when pressure is applied to the annular ledge, such as, for example, when the skirt is pressed against a sealing surface of the vial body.
Abstract: The invention provides methods for designing patterns for use in tinted contact lenses in which the patterns are generated using algorithms. The method of the invention provides an objective description of the pattern for purposes of tooling, metrology and manufacturing of a lens incorporating the pattern.
Abstract: The invention provides a multifocal ophthalmic lens that both corrects for the wearer's refractive prescription and takes into account pupil size of a specific individual or of a population of individuals. The invention provides a lens having an optic zone having a substantially circular central zone containing over-refracted near vision power and a diameter of about 2.5 mm or less.

Abstract: The invention provides contact lenses that substantially block either or both UV and blue light from entering the lens wearer's pupil by providing multiple concentric areas of certain materials that decrease or substantially eliminate the UV and blue light transmission. The lenses of the invention accomplish the light blocking without degrading the lens wearer's vision.

Abstract: The invention provides methods for correcting presbyopia and lenses for such correction in which production of a full range of multifocal lenses is accomplished using three rotationally symmetric, aspheric back surfaces, the design of which base curves is a function of refractive power.
Abstract: The invention provides tinted contact lenses that include a limbal ring that serves to enhance the definition of the wearer's iris resulting in the iris appearing larger to viewer's of the lens wearer. The lens also incorporates a plurality of tapered spokes that overlie a portion or all of the of the wearer's iris. The lenses of the invention may be used as cosmetic lenses for enhancing or altering an individual's iris.

Abstract: The invention provides a method for designing tinted contact lenses that permits the computer-assisted modeling of a tinted lens on-eye. The method of the invention provides a substantially accurate prediction as to the appearance of the lens on-eye and reduces the number of designs that must be clinically tested and the number of iterations that each design must go through.

Abstract: A method for designing contact lenses is provided in which direct correlation is made between an individual's subjective assessment of the lens' performance with the objective measurement of one or both of on-eye lens position and eyelid movement. The method permits generation of lens designs that have enhanced on-eye stability in less time than conventional design methods.

Abstract: An emulator including a beam splitter for splitting incoming light energy into a first component directed along a first optical path, and a second component directed along a second optical path distinct from the first optical path. The emulator includes a first receptacle positioned to pass light energy directed along only the first optical path. The first receptacle is capable of receiving an add lens for providing an add power. A beam combiner is positioned to combine light energy of the second component with light energy of the first component that has passed the first receptacle, i.e. to have the add power applied, and to direct the combined light energy along a common optical path. Additional receptacles are provided that are capable of receiving a sphere and/or a cylindrical lens in position to pass the combined light energy traveling along the common optical path.
Abstract: The invention provides lenses in which peak pressure under the lens wearer's eyelids is reduced. The invention provides lens designs that reduce or eliminate mechanical chaffing of the cornea even in lenses made of high modulus materials.

Abstract: The invention provides a multifocal lens that incorporates a substantially opaque ring. The lens design minimizes or eliminates ghosting of images. Additionally, the lens' performance on eye is more predictable than other progressive multifocal designs.
Abstract: The invention provides lenses for correcting presbyopia in which the near vision segments interfere at least about 50% less with distance vision than do the near vision segments in conventional contact lenses.
Abstract: The invention provides a method for designing a composite lens surface by using vector addition of the surface curvatures of two or more lens surfaces and then constructing a surface by numerical integration.

Abstract: The invention provides a lens in which the lens periphery is controlled as to each of thickness differential and both the rate of change from thinner to thicker regions and the shape of the transition from thinner to thicker regions within each of the dual thin zones. The lens of the invention substantially reduces the time for the lens' auto-positioning. Additionally, the lenses of the invention maintain their on-eye orientation better as compared to conventionally stabilized lenses.
