Abstract: Sets, kits or stocks of anti-myopia lenses and methods for their use, that do not require a clinician to measure peripheral refractive error in the eyes of myopic patients. Lenses having peripheral powers or defocus set in accordance with central corrective power will cover almost all normal myopes not worse than ?6D central refractive error. For example, a kit or set of lenses (50, FIG. 15) can have multiple parts or sub-sets each with a compartmented container with lenses arranged according to increments of central corrective power. The lenses of the first part have four steps of peripheral power or defocus to provide therapeutic effect and, while the lenses of the second part also have four steps, the level of therapeutic effect is higher. Other examples of sets, kits and stocks, as well as examples of lenses themselves, are disclosed together with methods of use.

Abstract: Sets, kits or stocks of anti-myopia contact or spectacle lenses, along with methods for their use, that do not require a clinician to measure peripheral refractive error in the eyes of myopic patients. Extensive surveys have shown that lenses having peripheral powers or defocus set in accordance with central corrective power will cover almost all normal myopes not worse than ?6D central refractive error. In one example, a kit or set of lenses (50, FIG. 15) can have multiple parts or sub-sets (52, 54) each comprising a compartmented container (56a, 56b) with lenses (58a, 58b) arranged according to increments of central corrective power (59a, 59b). The lenses (58a) of the first part (52) have four steps (60a, 61a, 62a, 64a) of peripheral power or defocus to provide therapeutic effect and, while the lenses (58b) of the second part (54) also have four steps (60b, 61b, 62b, 64b), the level of therapeutic effect is higher.

Abstract: A lens is provided that is capable of preventing or slowing the progression of myopia when worn by a person. The lens has a power profile that reduces on-axis and off-axis hyperopic defocus created by the optics of the eye by creating on-axis and off-axis myopic defocus. The on-axis and off-axis myopic defocus is created by providing light rays that pass through a central vision region of the optical portion and light rays that pass through a peripheral region of the optical portion an increase in positive (plus) power. The overall effect is to prevent or slow the progression of myopia without any perceptible degradation in the person's central vision.

Abstract: An ophthalmic lens series for reducing the progression of myopia through adequately correcting the peripheral retina, the series comprising more than one ophthalmic lens forming a series. Each ophthalmic lens of the series has a central power level common to the series. Each of the ophthalmic lenses of the series has one differential (peripheral minus central) power level selected from a variety of differential power levels. Providing a variety of differential power levels reduces the risk of over or under-correcting the peripheral retina of a particular eye.

Abstract: An optical arrangement of the Michelson interferometer type having a measuring arm for measuring optical properties of at least two mutually spaced regions in an optically transparent and/or diffusive object. A reference arm has a path length variation unit which generates a periodic change in path length for the radiation in the reference arm. Arranged in the measuring arm upstream of the object is a detour unit. The detour unit imparts a detour which is larger than at least one second measuring beam into at least one measuring beam. The detour unit selects a detour to be equal to a distance between regions to be measured in the object. Using the optical arrangement the object is irradiated with the aid of a number of measuring beams corresponding to the number of regions. In each case two measuring beams have an optical path difference which corresponds to a geometrical distance between two regions.
