(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 said sides of said central bridge portion, said upper and lower arms of each set having proximal ends fixed to one of said sides of said central bridge portion and distal ends fixed to said top and bottom parts of one of said eye wires respectively, and

c. means for connecting said central bridge portion of the insert to the corresponding central nose area of said shield,

d. said arms being bendable for adjusting the position and orientation of said lenses relative to said shield.

2. A protective eyewear article according to claim 1 , wherein each of said eye wires is adjustable in circumferential size between open to receive a lens and closed to securely hold said lens.

3. A protective eyewear article according to claim 1 , wherein each of said upper and lower arms has a middle section between said proximal and distal ends, and wherein only said proximal ends and distal ends contact said central portion and said eye wires respectively.

4. A protective eyewear article according to claim 1 , wherein said central bridge portion and said upper and lower arms, extending therefrom define, in top plan view an arc of predetermined curvature, said curvature being variable by bending said arms.

5. A protective eyewear article according to claim 1 , wherein said shield has opposite side edges, and wherein said means for releasably securing said shield on a wearer's face comprises a set of earpieces coupled to said opposite side edges respectively.

6. A protective eyewear article according to claim 1 , wherein said central bridge portion comprise an inverted U-shape.

7. A protective eyewear article comprising:

a. a transparent shield formed as a curved panel including a central nose area, said shield adapted for placement on a wearer's face;

b. a prescription lens insert adapted to be attached to said shield, to releasably hold prescription lenses, and to allow adjustment of position and orientation of said lenses, said insert comprising:

(i) an insert frame including a central bridge portion having opposite sides,

(ii) a set of eye wires, each defining a closed loop having top and bottom portions, each loop adapted to circumscribe and hold the edges of a lens, each loop fixed to one of said opposite sides of said insert frame, and

c. means for connecting said central bridge portion of said insert to the corresponding central nose area of said shield,

d. said insert frame being bendable for adjusting the position and orientation of said lenses relative to said shield.

8. A prescription lens insert adapted to releasably hold prescription lenses and to be releasably attached to a protective eye shield having a curved shield portion and a central nose area of said shield,

said insert comprising:

a. an insert frame including a central bridge portion having opposing sides,

b. a set of eye wires fixed to said opposing sides, each eye wire defining a closed loop having top and bottom portions, each loop adapted to circumscribe and hold the edges of a lens,

said central bridge portion holding said eye wires in spaced apart relationship, and

c. means for connecting said central bridge portion to the corresponding central nose area of said shield,

d. said frame being bendable for adjusting the position and orientation of said lenses relative to said shield.

9. A protective eyewear article comprising:

a. a shield formed as a transparent panel including a central nose area;

b. means for releasably securing said shield on a wearer's face;

c. a prescription lens insert adapted to be attached to said shield, to releasably hold prescription lenses and to allow adjustment of position and orientation of said lenses in relation to said shield, said 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 said sides of said central bridge portion, said upper and lower arms of each set having proximal ends fixed to one of said sides of said central bridge portion and distal ends fixed to said top and bottom parts of one of said eye wires respectively, and

d. means for connecting said central bridge portion of the insert to the corresponding central nose area of said shield,

e. said arms being bendable for adjusting the position and orientation of said lenses relative to said shield.

10. A protective eyewear article according to claim 9 , wherein said shield has opposite side edges, and wherein said means for releasably securing said shield on a wearer's face comprises a set of earpieces coupled to said opposite side edges respectively.

11. A protective eyewear article according to claim 9 , wherein said central bridge portion comprise an inverted U-shape.

12. A method of adjusting the position of the lenses of a protective eyewear article of claim 9 , comprising the steps of bending at least one of said sets of upper and lower arms relative to said central bridge portions:

(a) upward or downward, and/or

(b) forward or backward, and/or

(c) angularly by twisting.
