Abstract

Sunglasses with securement bows which are somewhat transmissive to ultraviolet light are taught which allow outdoor exposure without the sharp untanned lines normally seen on the side of the wearer'"'"'s head. Eyeglasses with securement bows which are somewhat transmissive to ultraviolet light are taught which allow outdoor exposure without the sharp untanned lines normally seen on the side of the wearer'"'"'s head. Eyeglasses and sunglasses with ultraviolet transmitting nose bridges are also taught.

Claims

1. Sunglasses comprising two lenses one for each of the left and right eye which lenses are secured each to a right and left bow for securement to a wearer'"'"'s ears which left and right bows are each at least partially transmissive to a predetermined wavelength of light and which bows are more transmissive to this predetermined wavelength of light than are the two lenses.

2. The sunglasses of claim 1 in which the predetermined wavelength of light is in the ultraviolet-B range.

3. The sunglasses of claim 1 in which the predetermined wavelength of light is in the ultraviolet range.

4. The sunglasses of claim 1 in which part of the bows contain polyvinylidene fluoride.

5. The sunglasses of claim 1 in which part of the bows contain a polyamide polymer.

6. The sunglasses of claim 1 in which the bows are connected to the lens through a hinge element.

7. Eyeglasses comprising two lenses one for each of the left and right eye which lenses are secured each to a right and left bow for securement to a wearer'"'"'s ears which left and right bows are each at least partially transmissive to a predetermined wavelength of light and which bows are more transmissive to this predetermined wavelength of light than are the two lenses.

8. The eyeglasses of claim 7 in which the predetermined wavelength of light is in the ultraviolet-B range.

9. The eyeglasses of claim 7 in which the predetermined wavelength of light is in the ultraviolet range.

10. The eyeglasses of claim 7 in which part of the bows contain polyvinylidene fluoride.

11. The eyeglasses of claim 7 in which part of the bows contain a polyamide polymer.

12. The eyeglasses of claim 7 in which the bows are connected to the lens through a hinge element.

13. The eyeglasses of claim 7 in which the bows have differing transmission of ultraviolet light in differing sections.

14. The eyeglasses of claim 13 in which the bow section of greatest ultraviolet transmission is between 3 and 5 cm in length.

18. The eyeglasses of claim 7 in which part of the nose bridge contains polyvinylidene fluoride.

19. The eyeglasses of claim 7 in which part of the nose bridge contains a polyamide polymer.

15. Eyeglasses comprising two lenses one for each of the left and right eye which lenses are secured each to a right and left bow for securement to a wearer'"'"'s ears and which lenses are connected to each other through a nose bridge which nose bridge is at least partially transmissive to a predetermined wavelength of light.

16. The eyeglasses of claim 15 in which the predetermined wavelength of light is in the ultraviolet-B range.

17. The eyeglasses of claim 15 in which the predetermined wavelength of light is in the ultraviolet range.
