Abstract: The present invention relates to a curable antistatic primer composition, comprising: (d) at least one polyalkylene oxide polymer; (e) at least a Lithium salt; (f) at least an amorphizer selected from at least a dendritic polymer. The present invention also relates to an optical article having at least one surface comprising an antistatic primer coating obtained by depositing on a substrate and curing said composition, and its production method.

Abstract: The invention relates to a method (20) for correcting an individual behavior for using a pair of spectacles in optimized conditions, said individual wearing frame (4). According to the invention said method comprises the following steps: —a step (24) of determining parameters that characterize the behavioral conditions of the individual using correcting means securely fastened to the frame of the frame (4) in the preceding various situations for a set time; —a step (26) of comparing said parameters with preset reference values; and —a step (28) of correcting the behavior of the individual using detecting means (1) that are securely fastened to the said frame (4), and that trigger when the difference between a parameter and the corresponding reference value diverges beyond a preset threshold value.
