Abstract: A method implemented by a computer means includes: obtaining a lens design; the lens design representing the variation of optical aberrations as a function of the angular view point; obtaining a set of subjective values representing the sensitivity of the user to a set of optical aberrations; and correlating the set of subjective values and the lens design based on the variation of optical aberrations so as to produce correlation information, advantageously for determining to which extent the lens design is adapted to the user from the correlation.

Abstract: The present invention relates to an improved method for securing a computer connected to an insecure network when the computer is not utilizing the insecure network, wherein the computer is installed with a program managing the connection with the insecure network, which includes the steps of determining whether the computer is active, deactivating the computer from the insecure network when it is determined that the computer is inactive, and waiting for a predefined time period to repeat the method.

Abstract: The present invention relates to an improved system and method for securing a computer having at least one network interface connected to an insecure network when the computer is not utilizing the insecure network, which includes the steps of building an array of at least one network interface including a unique identifier for uniquely identifying each at least one network interface and a status associated to each unique identifier for indicating the status of the unique identifier, determining whether the computer is active, turning off the insecure network when it is determined that the computer is inactive, turning on the network when it is determined that the computer is active, and waiting for a predefined time period to repeat from the step of determining whether the computer is active.
