A method of forming a device, the method including: depositing a first photoresist layer over a substrate, forming an array of seed lenses by patterning and reflowing the first photoresist layer, a dimension of the array of seed lenses varying across the substrate, forming a second photoresist layer over the array of seed lenses, and forming a microlens array by patterning and reflowing the second photoresist layer.

Exemplary embodiments of the present disclosure provide a method and apparatus for forming an ophthalmic lens. An exemplary method includes providing a plurality of posterior tools each having a posterior optic defining surface and a plurality of anterior tools each having an anterior optic defining surface, wherein each one of the plurality of posterior tools has a different central posterior optic defining surface including a unique conic section. The method further includes selecting one of the plurality of posterior tools and one of the plurality of anterior tools based on a criteria, and forming a posterior mold by the selected one of the plurality of posterior tools and an anterior mold by the selected one of the plurality of anterior tools, the posterior mold and the anterior mold operable to form an ophthalmic lens having the criteria.

A toric contact lens (1) having a front surface and a rear surface, one of said front and rear surfaces includes a toric optical zone and a lens edge surrounding the contact lens (1). The contact lens further has a ballast axis (3) and includes at least one ballast mark (41, 42, 43) identifying the position of the ballast axis (3). Each ballast mark (41, 42, 43) includes a one-dimensional dot pattern (5) having a lens identification code and being arranged to extend radially towards the lens edge at an angular position relative to the position of the ballast axis (3). The angular position of the one-dimensional dot pattern identifies the position of the ballast axis.

Apparatuses, systems and methods for providing improved intraocular lenses (IOLs), include features for reducing side effects, such as halos, glare and best focus shifts, in multifocal refractive lenses and extended depth of focus lenses. Exemplary ophthalmic lenses can include a continuous, power progressive aspheric surface based on two or more merged optical zones, the aspheric surface being defined by a single aspheric equation. Continuous power progressive intraocular lenses can mitigate optical side effects that typically result from abrupt optical steps. Aspheric power progressive and aspheric extended depth of focus lenses can be combined with diffractive lens profiles to further enhance visual performance while minimizing dysphotopsia effects. The combination can provide an increased depth of focus that is greater than an individual depth of focus of either the refractive profile or the diffractive profile.
