A system/method allowing personalized ex vivo customization of a generic ophthalmic lens blank (OLB) or ophthalmic lens with known diopter (OKD) based on localized field-measured patient characteristics is disclosed. The OLB is composed of an acrylic material that has been infused with an ultraviolet (UV) absorbing compound rendering it amenable to customized spatial modification (CSM) of its refractive index via the use of pulsed laser radiation (PLR). The CSM of refractive index eliminates the need for remote laboratory fabrication of a customized intraocular lens (IOL) for the patient. The OLB is retained within a secured lens container (SLC) providing for precise physical orientation of the OLB haptics and OLB lens structure with respect to the application of PLR to the OLB. The SLC contains a lens filler material (LFM) covering the OLB and is hermetically sealed after the OLB has been positioned within the SLC interior and prior to sterilization of the SLC+OLB combination.

A vision apparatus implemented as an optical device is disclosed. The optical device comprises a plurality of small apertures in an opaque material that is attached to a pair of eyeglasses or is a contact lens. The number and arrangement of small apertures defines the field of view and brightness of the image projected onto the user's retina. The opaque material is a collimator, and only small areas of the user's retina are illuminated by cones of light passing through the small apertures. Therefore, all of the light is rendered in focus. The optical device resolves the refractive errors of the eye of the user, improving the visual acuity of the user in any activity that requires depth of field with a large and bright field of view. Two optical devices, one for each eye, provide binocular vision with a variety of aperture arrangements to suit the user's needs.
