Abstract: Disclosed is a spectacle frame including a pair of lens holding rims interconnected by a bridge, each rim being encircling and holding a lens in a central aperture of the rim, each rim being linked laterally to a temple, each rim having at least one cut allowing expansion of the central aperture or retraction and closure of the central aperture by closing the cut. The spectacle frame further includes a lock allowing closure and locking the cuts of the rims. The bridge attaches to the rims to allow attachment of one bridge chosen among bridges having different shapes and/or sizes and/or decorations to adapt the spectacle frame to different morphological features of wearers and/or to choices of the wearers, and wherein the rims and the bridge includes complementary bridge connector to attach and connect the bridge to each rim. A kit of parts and an eyewear are also disclosed.

Abstract: A subjective refraction apparatus provides a variable optical correction along an optical axis. The subjective refraction apparatus includes a pair of lenses mounted on a mount in such a manner that the lenses are movable with respect to each other in a direction perpendicular to the optical axis for generating a variable spherical power along the optical axis. The mount is provided with a support defining a space for removably receiving an additional lens on the optical axis.

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.
