1. Fluidic glasses for correcting refractive errors of a human or animal, the fluidic glasses comprising:
at least one flexible fluidic lens having an outer housing and a flexible membrane supported within the outer housing, the flexible membrane at least partially defining a chamber that receives a fluid therein;
a fluid control system operatively coupled to the at least one flexible fluidic lens, the fluid control system configured to insert an amount of the fluid into the chamber of the at least one flexible fluidic lens, or remove an amount of the fluid from the chamber of the at least one flexible fluidic lens, in order to change the shape of the at least one flexible fluidic lens in accordance with the amount of fluid therein, thereby correcting the refractive errors of an eye of a human or animal; and
a solid plate disposed adjacent to the chamber of the at least one flexible fluidic lens, the solid plate being in a form of a transitional lens with a light-sensitive pigment that changes color based upon the amount of light absorbed by the transitional lens;
wherein the transitional lens comprises a central region that is free of the light-sensitive pigment, and a peripheral region surrounding the central region that contains the light-sensitive pigment so that the peripheral region becomes darker when activated by light, thereby producing a pinhole transitional lens where objects viewed through the central region of the pinhole transitional lens are in focus for the human or animal; and
wherein the pinhole transitional lens is in a form of a Fresnel diffractive lens that includes multiple zones of prisms so as to provide a plurality of fixed diffractive plus zone focal points, the multiple zones of the Fresnel diffractive lens being for presbyopia correction of near vision of the human or animal, and the at least one flexible fluidic lens being for myopia correction of distance vision of the human or animal.
