9. The spectacles set, as recited in claim 1 , wherein each of said extension arms is bent to form an angled neck portion between said distal end and said root end portion to magnetically engage with said respective magnetic seat, so as to magnetically mount said detachable shelter frame in front of said primary spectacle frame.

10. The spectacles set, as recited in claim 9 , wherein said two supporting arms are in L-shaped and extended from said shelter frame to ride on said primary bridge, wherein said two magnetic seats comprises a magnetic housing extended from a rear end of said respective supporting arm towards said respective extension arm and a magnet mounted in said magnetic housing which is arranged to face toward and align with said angled neck portion of said respective extension arm of said nose support when said detachable shelter frame is mounted in front of said primary spectacle frame.

11. The spectacles set, as recited in claim 10 , wherein each of said magnets has a thickness smaller than a depth of said respective magnetic housing to define an engaging groove when said magnet is embedded in said magnetic housing for fittedly engaging with said angled neck portion of said respective nose support.

12. The spectacles set, as recited in claim 11 , wherein each of said magnetic housings further has at least an edge opening formed at a surrounding wall thereof to communicate with said engaging groove for fittedly interlocking with said angled neck portion of said respective extension arm so as to securely mount said detachable shelter frame in front of said primary spectacle frame.

13. The spectacles set, as recited in claim 1 , wherein said two supporting arms are in L-shaped and extended from said shelter frame to ride on said primary bridge, wherein said two magnetic seats comprises a magnetic housing extended from a rear end of said respective supporting arm towards said respective extension arm and a magnet mounted in said magnetic housing which is arranged to face toward and align with said distal end of said respective extension arm when said detachable shelter frame is mounted in front of said primary spectacle frame.

14. The spectacles set, as recited in claim 13 , wherein each of said magnets has a thickness smaller than a depth of said respective magnetic housing to define an engaging groove when said magnet is embedded in said magnetic housing for fittedly engaging with said distal end portion of said respective extension arm.

15. The spectacles set, as recited in claim 1 , wherein said two supporting arms are rearwardly extended from two lower portions of said two inner sides of said shelter frame respectively towards said extension arms, wherein said two magnetic seats comprises a magnetic housing extended from a rear end of said respective supporting arm towards said respective extension arm and a magnet mounted in said magnetic housing which is arranged to face toward and align with said respective extension arm of said nose support when said detachable shelter frame is mounted in front of said primary spectacle frame.

16. The spectacles set, as recited in claim 15 , wherein each of said magnets has a thickness smaller than a depth of said respective magnetic housing to define an engaging groove when said magnet is embedded in said magnetic housing for fittedly engaging with said shoulder portion of said respective nose support.

17. The spectacles set, as recited in claim 16 , wherein each of said magnetic seats, having a U-shaped cross section, is rearwardly and suspendedly affixed to said rear end of said respective supporting arm to fittedly engage with said respective extension arm.
