The stabilized contact lens methods and apparatus disclosed herein provide improved stabilization of a contact lens placed on a cornea of an eye. The contact lens comprises stabilization zones that allow the lens to repeatedly and consistently orient on the cornea such that a sensing zone located on the lower portion of the lens is located inferiorly to engage the lower eyelid. The stabilized contact lens can provide a lower pressure sensing zone with decreased thickness for pressure or other sensing related to the lower eyelid. The decreased thickness has the advantage of improving coupling between forces from an eyelid and a lower chamber of a fluidic module. The improved coupling allows increased amounts of fluid to move between the lower chamber and an upper optical chamber coupled to the lower chamber, such that the upper chamber can increase curvature and optical power in response to pressures of the eyelid.

Disclosed are lenses and methods for verifying a lens with an induced aperture. The lenses can have a geometry that, among other things, maintains a centered position about a wearer's eye to prevent more than a permissible amount of movement of the lens relative to the eye. Further disclosed is a method for verifying the power profiles used with the lens, and a lens that can have a single power profile for a wide range of presbyopia.

Induced aperture lens and method

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 &#x2212;6D central refractive error. For example, a kit or set of lenses (, FIG.) 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.

Myopia control means

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 &#x2212;6D central refractive error. In one example, a kit or set of lenses (, FIG.) can have multiple parts or sub-sets () each comprising 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.

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.

Lens design and method for preventing or slowing the progression of myopia

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 &#x2212;6 D central refractive error. In one example, a kit or set of lenses (, FIG.) can have multiple parts or sub-sets () each comprising 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 pro vide 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.

An ophthalmic lens includes spherical aberration in an amount that accounts for spherical aberration introduced into the lens during the manufacturing process and/or spherical aberration differences in the manufactured lens measured off of the eye and measured on the eye. The result is a lens-and-eye optical system is free or substantially free of spherical aberration, i.e., having only negligible spherical aberration. Because the optical system is free or substantially free of spherical aberration, there is no or only negligible coma induced by the normal misalignment of the lens optical axis and the eye's primary line of sight. The result is a lens-and-eye optical system that provides enhanced optical performance and visual quality. Also disclosed are methods of designing and manufacturing lenses with spherical aberration adjustments to account for manufacturing process changes and off-eye to on-eye differences.
