1. Eyewear, comprising:

a frame;

a lens and at least one temple bar hingedly connected to said frame,

a nose piece structure for attachment to a central portion of said lens, said nose piece structure defining a channel, said channel defining ledge indents for mating engagement with ledge protrusions defined within the central portion of said lens; and

a recessed area of said lens defines an inverted V-shape or U-shape and is formed in a central portion of the lens, said recess including a perimetral edge, the ledge protrusions extending inwardly from said perimetral edge, said ledge protrusions defining a first horizontal ledge and a second horizontal ledge, said first horizontal ledge and said second horizontal ledge including a substantially horizontal projection forming a narrow shelf on said lens for engaging with a nose-piece structure,

a ledge support area for both the first and second horizontal ledge extends along a slope towards a bottom portion of said recess, each ledge support area defines a gradual declining portion and a steep declining portion, said first horizontal ledge and said second horizontal ledge substantially aligned with a common, horizontal ledge axis,

an upper portion of said recess extending above said common, horizontal ledge axis having a mushroom-shape and defining a sufficient clearance area to allow for ledge indents within the channel of said nose piece structure to clear a corner of said horizontal ledge, the nose piece structure having indents which are proportionally sized to snap over said horizontal ledge area, and

an lower portion of said recess extending below said common, horizontal ledge axis, said lower portion having a height 50 percent or more greater than the height of said upper portion, a width of said lower portion increasing from said horizontal ledge axis to bottom end of said recess, the width of the bottom end of the recess is 50 percent or more greater in height than the height of the lower portion and the upper portion combined.

2. Eyewear, comprising:

a frame;

a lens and at least one temple bar connected to said frame,

a nose piece structure for connecting to a central portion of said lens, said nose piece structure defining a channel, said channel defining ledge indents for mating engagement with ledge protrusions defined within the central portion of said lens; and

a recessed area of said lens is formed in a central portion of the lens, said recess including an edge, the ledge protrusions extending from said edge, said ledge protrusions defining a first ledge and a second ledge, said first ledge and said second ledge including a substantially horizontal projection forming a shelf on said lens for engaging with a nose-piece structure,

a ledge support area for both the first and second ledge extends towards a bottom portion of said recess, each ledge support area defines a gradual declining portion and a steep declining portion, said first ledge and said second ledge substantially aligned with a common horizontal ledge axis, and

an upper portion of said recess extending above said common horizontal ledge axis defining a sufficient clearance area to allow for ledge indents within the channel of said nose piece structure to clear a corner of said ledge, the nose piece structure having indents which are proportionally sized to snap over said ledge area.

3. The eyewear of claim 2 , wherein the recessed area of said lens defines an inverted V-shape or U-shape.

4. The eyewear of claim 2 , wherein said upper portion of said recess extending above said common horizontal ledge axis defines a mushroom shape.

5. The eyewear of claim 2 , wherein recess includes a perimetral edge and the ledge protrusions extend from said perimetral edge.

6. The eyewear of claim 2 , further comprising:

a lower portion of said recess extending below said common, horizontal ledge axis, said lower portion having a height greater than the height of said upper portion.

7. The eyewear of claim 6 , further comprising:

a width of said lower portion increasing from said horizontal ledge axis to bottom end of said recess.

8. Eyewear, comprising:

a frame;

a lens and at least one temple bar connected to said frame,

a nose piece structure for connecting to a central portion of said lens, said nose piece structure defining a channel, said channel defining ledge protrusions for mating engagement with ledge indents defined within the central portion of said lens; and

a recessed area of said lens is formed in a central portion of the lens, said recess including an edge, the ledge indents extending from said edge, said ledge indents defining a first indent and a second indent, said first indent and said second indent including a substantially horizontal projection forming a shelf on said lens for engaging with a nose-piece structure,

an indent support area for both the first and second indents extends towards a bottom portion of said recess, each indent support area defines a gradual declining portion and a steep declining portion, said first indent and said second indent substantially aligned with a common horizontal indent axis, and

an upper portion of said recess extending above said common, horizontal indent axis defining a sufficient clearance area to allow for ledge protrusions within the channel of said nose piece structure to clear a corner of said indent, the nose piece structure having ledge protrusions which are proportionally sized to snap over said indent area.

9. The eyewear of claim 8 , wherein the recessed area of said lens defines an inverted V-shape or U-shape.

10. The eyewear of claim 8 , wherein said upper portion of said recess extending above said common indent axis defines a mushroom shape.

11. The eyewear of claim 8 , wherein recess includes a perimetral edge and the ledge protrusions extend from said perimetral edge.

12. The eyewear of claim 8 , further comprising:

a lower portion of said recess extending below said common, horizontal indent axis, said lower portion having a height greater than the height of said upper portion.

13. The eyewear of claim 12 , further comprising:
