1. A warming device which warms a distal portion of an optical instrument, the warming device comprising: a double walled cylindrical tube having a rigid and uninterrupted internal wall, an external wall, a proximal end, an open distal portion, an insulation chamber between the internal wall and the external wall, and an annular central cavity formed inward in relation to the internal wall;a rigid protrusion extending from the proximal end into the annular central cavity, the protrusion sized and shaped to receive a lens portion of the optical instrument;a circular cap sized to attach to the distal portion of the double walled cylindrical tube;an insulation layer in the insulation chamber between the internal wall and the external wall, the insulation chamber separate from and sealed with respect to the annular central cavity; anda heating element enclosed within the annular central cavity. 2. The warming device according to claim 1 wherein the protrusion comprises a plurality of steps of decreasing circumference toward a distal portion of the protrusion. 3. The warming device according to claim 1 wherein the heating element comprises a conductive material. 4. The warming device according to claim 1 wherein the heating element is heated prior to use by microwaving the warming device. 5. The warming device according to claim 1 wherein the heating element is heated prior to use by inserting the warming device into a conventional oven type surgical warmer. 6. The warming device according to claim 1 wherein the insulation layer comprises air. 7. The warming device according to claim 1 wherein the warming device is disposable. 8. The warming device according to claim 1 comprising an attachment mechanism attached to the proximal end of the double walled cylindrical tube, the attachment mechanism configured to removably attach the warming device to a surgical drape or table. 9. The warming device according to claim 1 comprising a flexible grommet surrounding a proximal end of the protrusion. 10. A warming device which warms a distal portion of a surgical optical instrument, the warming device comprising: a first cylindrical body having: a first end,a second closed end, anda first radius;a second cylindrical body positioned at least partially within the first cylindrical body and having: a first end,a second end, anda second radius smaller than the first radius;a third cylindrical body positioned at least partially within the second cylindrical body and having:a first opened end,a second closed end, anda third radius smaller than the second radius, the first opened end of the third cylindrical body comprising an opening configured to receive the distal portion of the surgical optical instrument;an annular wall closing the first ends of the first and second cylindrical bodies to form an annularly uninterrupted and sealed insulation chamber between the first and second cylindrical bodies;a sealed annularly uninterrupted heating chamber between the second and third cylindrical bodies; anda heating element positioned within the sealed annular heating chamber. 11. The warming device according to claim 10 wherein the third cylindrical body comprises a plurality of steps of decreasing circumference toward the closed end of the third cylindrical body. 12. The warming device according to claim 10 comprising a flexible grommet surrounding the first opened end of the third cylindrical body. 13. The warming device according to claim 10 wherein at least one of the first, second, and third cylindrical bodies comprises a thermoplastic or thermoset material.
