In one embodiment, the eyeglass orbitals are investment cast from substantially pure titanium or a titanium based alloy. ## Claims ### Claim 1 Articulated dual lens eyeglasses, comprising: first and second orbitals, each orbital having a medial and a lateral zone; a medial connector on the medial zone of each orbital; and a bridge movably connected to the medial connector on each orbital; wherein each orbital is moveable throughout a range of motion of no more than about 15.degree. with respect to the bridge. ### Claim 2 (depends on 1) Articulated dual lens eyeglasses as in claim 1, wherein each of said first and second orbitals comprises an annular seat for receiving a lens. ### Claim 3 (depends on 2) Articulated dual lens eyeglasses as in claim 2, further comprising a retainer for retaining said lens in the annular seat. ### Claim 4 (depends on 1) Articulated dual lens eyeglasses as in claim 1, wherein said first and second orbitals comprise a metal. ### Claim 5 (depends on 4) Articulated dual lens eyeglasses as in claim 4, wherein said metal comprises titanium. ### Claim 6 (depends on 1) Articulated dual lens eyeglasses as in claim 1, further comprising first and second earstems connected to said eyeglasses. ### Claim 7 (depends on 1) Articulated dual lens eyeglasses as in claim 1, wherein the range of motion is limited by contact between an abutment surface on the bridge and an opposing abutment surface on an orbital. ### Claim 8 (depends on 1) Articulated dual lens eyeglasses as in claim 1, wherein each orbital is moveable throughout a range of motion of no more than about .+-.10.degree. with respect to the bridge. ### Claim 9 (depends on 1) Articulated dual lens eyeglasses as in claim 1, wherein each orbital is moveable throughout a range of motion of no more than about .+-.5.degree. with respect to the bridge. ### Claim 10 (depends on 1) Articulated dual lens eyeglasses as in claim 1, wherein the bridge further comprises a flange having an aperture therethrough for moveably connecting to the medial connector. ### Claim 11 (depends on 1) Articulated dual lens eyeglasses as in claim 1, further comprising first and second cast metal earstems pivotably connected to the first and second orbitals, respectively. ### Claim 12 (depends on 11) Articulated dual lens eyeglasses as in claim 11, further comprising at least a first link connected in between the first orbital and the first ear stem. ### Claim 13 (depends on 1) Articulated dual lens eyeglasses as in claim 1, further comprising first and second lenses, wherein the first orbital completely surrounds the first lens. ### Claim 14 (depends on 1) Articulated dual lens eyeglasses as in claim 1, further comprising first and second lenses, wherein the first orbital surrounds only a portion of the first lens. ### Claim 15 (depends on 1) Articulated dual lens eyeglasses as in claim 1, wherein the bridge comprises a metal. ### Claim 16 (depends on 15) Articulated dual lens eyeglasses as in claim 15, wherein the metal comprises titanium. ### Claim 17 Articulated dual lens eyeglasses, comprising: first and second metal orbitals, each orbital having a medial and a lateral zone; first and second lenses in the first and second orbitals, respectively; a metal bridge pivotably connected to the medial zone on each orbital; first and second links connected to a lateral zone on each of the first and second orbitals; and first and second ear stems connected to the first and second links; wherein each orbital is moveable throughout a range of motion of no more than about .+-.10.degree. with respect to the bridge. ### Claim 18 (depends on 17) Articulated dual lens eyeglasses as in claim 17, further comprising a resilient pad in the joint between the bridge and each orbital to bias the joint to a particular orientation. ### Claim 19 (depends on 18) Articulated dual lens eyeglasses as in claim 18, wherein the eyeglasses comprise investment cast metal. ### Claim 20 (depends on 19) Articulated dual lens eyeglasses as in claim 19, wherein said metal comprises titanium. ### Claim 21 Articulated dual lens eyeglasses, comprising: first and second metal orbitals, each orbital having a medial and a lateral zone; a first medial connector on the medial zone of the first orbital; a metal bridge pivotably connected at a joint between the first medial connector on the first orbital and the bridge; and a resilient pad in the joint to bias the joint to a particular orientation; wherein each orbital is moveable throughout a range of motion of no more than .+-.10.degree. with respect to the bridge. ### Claim 22 (depends on 21) Articulated dual lens eyeglasses as in claim 21, wherein said metal comprises titanium. ### Claim 23 (depends on 22) Articulated dual lens eyeglasses as in claim 22, further comprising first and second earstems connected to said eyeglasses. ### Claim 24 (depends on 22) Articulated dual lens eyeglasses as in claim 22, wherein each orbital is moveable throughout a range of motion of no more than about .+-.5.degree. with respect to the bridge. ### Claim 25 (depends on 23) Articulated dual lens eyeglasses as in claim 23, further comprising at least a first link connected in between the first orbital and the first ear stem.
