    Abstract: The invention is directed to a device (10, 10a - 10d) comprising: a set of on- chip circuits (110 - 160, 170, 180), each of the circuits configured to generate a magnetic field (300) perpendicular to a planar surface of the set when energized; a ferrofluidic layer (40) interfaced to the planar surface; and a logic circuit (50) configured to selectively energize (200, 200a) one ore more circuits of the set such as to generate a magnetic field at the energized circuits and a deformation (41, 44, 45) of the ferrofluidic layer in response thereto and to modulate optical beams (IR1, IR2) directed to the ferrofluid layer. Preferably, an additional liquid layer (60) is interfaced to the ferrofluid layer, opposite to the on-chip circuits, which is not miscible with the ferrofluid layer. The invention can be applied to micro- display/projection devices, programmable optical reflecting lenses, or to micro- molding applications for surface replication.

    Abstract: Methods, devices, and systems for manufacturing ophthalmic lenses using direct injection molding are described. The present methods, devices, and systems include a mold block having a first mold insert and a second mold insert defining a lens-shaped cavity between them. A raised non-uniform region that projects into the lens-shaped cavity is incorporated in a peripheral zone of the molding surface of at least one of the mold inserts. When an ophthalmic lens is formed using the described mold block, at least one depression is produced in the lens. A gate placed at the non-uniform region allows the depression to hide any gate witness that may form when the mold is closed or separated.

    Abstract: The invention provides a method of moulding a vision correction lens from a transparent resin. The resin is introduced into a mould cavity, the sides of which cavity which correspond to the front and rear surfaces of the lens being formed by two sheets, at least one of which is flexible. The amount of resin in the cavity is adjusted to deform the flexible sheet(s) so that the shape of the lens defined by the sheet(s) will provide a desired power, and the resin is then cured. The sheets can be transparent, and a user can look through them as the amount of resin is adjusted, to ensure that the lens is of the desired power. Further, the amount of resin in the cavity can be adjusted to accommodate changes in the refractive index of the resin as it cures.
