The present invention illustrates various methods of attaching a pair of eyeglass lenses or a lens shield to an eyeglass frame using magnets or magnetically attractive material. The magnetic attachment methods are beneficial because they allow the user to have interchangeable lenses or shields for indoor and outdoor use, enhancing their visual acuity during work or play. The lenses may be tinted, prescription, protective eyewear, or plano. The magnetic lenses are convenient and user friendly, allowing intuitive, tool-less interchangeability with no need to twist or stress the frame. These methods of attachment require no specific instructions or tools when the user replaces lenses.

A protective eyewear article including:a. a transparent shield formed as a curved panel including a central nose area, the shield adapted for placement on a wearer's face.b. a prescription lens insert adapted to be attached to the shield, to releasably hold prescription lenses and to allow adjustment of position and orientation of the lenses in relation to the shield, the insert comprising:(i) a set of eye wires, each defining a closed loop having top and bottom parts, each loop adapted to circumscribe and hold the edges of a lens,(ii) a central bridge portion having opposite sides, and(iii) a set of upper and lower arms extending outward from each of the sides of the central bridge portion, the upper and lower arms of each set having proximal ends fixed to one of the sides of the central bridge portion and distal ends fixed to the top and bottom parts of one of the eye wires, respectively, andc. means for connecting the central bridge portion of the insert to the corresponding central nose area of the shield,d. the arms being bendable for adjusting the position and orientation of the lenses relative to the shield.

An improved dual-filter lens for protective eyewear that combines a first filter for blocking essentially 100% of UV light, and second filter for filtering blue light. The first filter may comprise a multi-layered dielectric mirror layer 14 or Rugate filter 50, and the second filter may comprise dye-impregnated lens layer(s) 16, 18 or Rugate filter 50. The first filter blocks essentially 100% of UV light, while the second filter establishes an increasing transmission profile that cuts on sharply at approximately 415 nm, and establishes an increasing transmission profile between approximately 415 nm to about 475 nm. The cut-on slope rises approximately 0.15% in transmissivity for every nanometer of increasing wavelength change, with a maximum filtering effect within the 440-465 nm range. These dual filters provide a balanced light transmission profile that reduces harmful light transmission and prevents macular degeneration, cataracts and other ocular injuries, while still preserving visual acuity.

The present invention provides protective eyewear, also referred to as sport goggles, where the lens and the flexible frame are easily separated and interchangeable. The lens and the flexible frame are both available in a variety of colors. Therefore, the wearer can select and easily assemble a preferred color combination. More specifically, the protective eyewear includes a lens received within a flexible frame and a strap that is permanently attached to the lens for securing the eyewear to a wearer's face. There are at least two connection apertures spaced around an outer perimeter of the lens. The flexible frame has at least two connection protrusions that are aligned with the connection apertures in the lens for removably receiving the connection apertures.
