Abstract

A protective eyewear device features a frame for supporting the protective eyewear on a user'"'"'s head in a position placing one or more transparent or translucent viewing lenses of the eyewear device in front of the user'"'"'s eyes, and one or more deposits of a radiation-reactive material located at or adjacent the one or more lenses and responsive to ionizing radiation exposure to produce a visual indication of said exposure to the user within a normally used field of vision of said user.

Claims

2. An eye protection and radiation warning device comprising one or more transparent or translucent viewing lenses to be worn in front one or both eyes of a user, and one or more deposits of a radiation-reactive material that is carried with the one or more lenses and is responsive to ionizing radiation exposure to produce a visual indication of said exposure to the user at a position within a normally used field of vision of said user when the one or more viewing lenses are worn.

8. A method of producing an eye protection device that provides a wearer with visual warning signals in response to ionizing radiation exposure, the method comprising providing the eyewear with at least one deposit of radiation-reactive material that is carried on the eye protection device at or adjacent one or more transparent or translucent viewing lenses thereof and is responsive to said ionizing radiation exposure in a manner producing a visual indication of said exposure within a normally used field of vision of the wearer when the one or more lenses are worn in front of a user'"'"'s eyes.

1. A protective eyewear device comprising a frame for supporting the protective eyewear on a user'"'"'s head in a position placing one or more transparent or translucent viewing lenses of the eyewear device in front of the user'"'"'s eyes, and one or more deposits of a radiation-reactive material located at or adjacent the one or more lenses and responsive to ionizing radiation exposure to produce a visual indication of said exposure to the user within a normally used field of vision of said user.

3. The device of claim 1 wherein the reactive material is embedded within the one or more lenses.

4. The device of claim 1 wherein the one or more lenses comprise polycarbonate.

5. The device of claim 1 wherein the one or more deposits comprise a phosphor that luminesces under exposure to ionizing radiation.

6. The device of claim 1 wherein the one or more deposits comprise cadmium tungstate.

7. The protective eyewear of claim 1 wherein the one or more deposits comprise calcium tungstate.

9. The method of claim 8 comprising placing the at least one deposit of radiation-reactive material at the one or more viewing lenses.

10. The method of claim 8 comprising impregnating at least one of the one or more viewing lenses with the radiation-reactive material.

11. The method of claim 8 wherein the one or more lenses comprise polycarbonate.

12. The method of claim 8 wherein the one or more deposits comprise a phosphor that luminesces under exposure to ionizing radiation.

13. The method of claim 8 wherein the one or more deposits comprise cadmium tungstate.

12-1. The method of claims 8 wherein the one or more deposits comprise calcium tungstate.
