Abstract: Disclosed is a stack of individually separable packages for a plurality of contact lenses, each individual lens being packaged between a first surface and a second surface, wherein the first surface is provided by a first one of the individually separable packages and the second surface is provided by a second one of the individually separable packages.

Abstract: Disclosed is a device adapted to measure intraocular pressure comprising: a corneal contact lens having a pressure sensor mounted in a recess or cavity in the contact lens, and wherein the contact lens has a back surface which is formed so as to protrude in a desired portion beyond the profile of the adjacent part of the lens and thus to press against the cornea, which protruding portion experiences a reactive deformation which is detected directly or indirectly by the pressure sensor.

Abstract: The invention relates to a method of designing a soft contact lens, said lens having a central optic zone and with a peripheral zone around the central optic zone; the method comprising the steps of: (a) defining a back surface of the lens which is a satisfactory fit to the surface of a subject's cornea; (b) defining a front surface of the lens over at least the central optic zone, which surface is selected so as to ameliorate the subject's vision defects; (c) checking that the lens meets a desired range of thickness values at one or more selected parts of the lens and, if not, recalculating the front surface over at least the central optic zone so as to meet said desired thickness value range, wherein the lens is to be made of a substance having a Young's modulus in the range 0.08 to 0.40 MPa, and wherein the junction thickness of the lens is in the range 0.15-0.40 mm.
