The sports spectacles comprise a lens-carrying frame (10) with an upper cross-member (11) including two branches (11a, 11b) extending symmetrically from a central portion (12) towards respective opposite free ends (13a, 13b) and, on the outer side (8) of each branch, there is a surface (18) with a helical profile extending from a rim (19) for the attachment of the corresponding lens (L), with the helix facing so as to deflect an air-flow striking the corresponding lens (L) towards the respective free end (13a, 13b).
