9. The spectacles set, as recited in claim 8 , wherein each said magnet has a thickness smaller than a depth of said respective magnetic housing so as 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 nose support.

10. The spectacles set, as recited in claim 9 , wherein said distal end portion of each of said extension arms forms as an engaging member extended frontwardly, wherein each of said engaging members is fittedly received in said engaging groove of said respective magnetic seat so as to alignedly guide said magnetic seats to magnetically engage with said extension arms respectively.

11. The spectacles set, as recited in claim 1 , wherein each of said nose supports has a shoulder portion formed at a front side of said respective extension arm between said distal end portion and said root portion, wherein said shoulder portions of said nose supports are facing frontwardly to magnetically engage with said magnetic seats respectively.

12. The spectacles set, as recited in claim 11 , wherein each of said magnetic seats comprises a magnetic housing, having a U-shaped cross section, rearwardly and suspendedly extended from said respective supporting arm and a magnet mounted in said magnetic housing, which is arranged to face towards and align with said shoulder portion of said respective nose support when said detachable shelter frame is mounted in front of said primary spectacle frame.

13. The spectacles set, as recited in claim 12 , wherein each said magnet has a thickness smaller than a depth of said respective magnetic housing so as to define an engaging groove between two sidewalls of said magnetic housing when said magnet is embedded in said magnetic housing for fittedly engaging with said shoulder portion of said respective nose support.

14. The spectacles set, as recited in claim 13 , wherein said two supporting arms are rearwardly and inclinedly extended from two lower portions of two inner sides of said shelter frame respectively towards said shoulder portions of said extension arms of said nose supports so as to alignedly guide said magnetic seats to magnetically engage with said shoulder portions of said nose supports respectively.

15. The spectacles set, as recited in claim 11 , wherein said two supporting arms are rearwardly and inclinedly extended from two lower portions of two inner sides of said shelter frame respectively towards said shoulder portions of said extension arms of said nose supports so as to alignedly guide said magnetic seats to magnetically engage with said shoulder portions of said nose supports respectively.

16. The spectacles set, as recited in claim 1 , wherein each of said nose supports has a shoulder portion formed at a front side of said respective extension arm between said distal end portion and said root end portion, wherein said shoulder portions of said nose supports are facing rearwardly to magnetically engage with said magnetic seats respectively.

17. The spectacles set, as recited in claim 16 , wherein each of said magnetic seats comprises a magnetic housing, having a U-shaped cross section, rearwardly and suspendedly extended from said respective supporting arm and a magnet mounted in said magnetic housing, which is arranged to frontwardly face towards and align with said shoulder portion of said respective nose support when said detachable shelter frame is mounted in front of said primary spectacle frame.
