Contact lenses displaying reduced indoor glare
The present invention relates to contact lenses which reduce indoor glare and provide improved comfort to the wearer. The contact lenses of the present invention have, at about body temperature, a percent transmission between 70 to 90% across the region of 420-700 nm.
1. A contact lens having, at about body temperature, a percent transmission between 70 to 90% across the region of 420-700 nm.
2. A contact lens comprising a central circular area centered at a geometric center of the lens and having a diameter of about 1 to about 9 mm and a peripheral zone, wherein said central circular area has, at body temperature, a percent transmission between 70 to 90% across the region of 450-660 nm.
3. The contact lens of claim 2 wherein said peripheral zone has a percent transmission in the UV range of less than about 20%.
4. The contact lens of claim 2 wherein said peripheral zone is capable of substantially blocking the transmittance of UV, blue light or both.
5. The contact lens of claim 2 wherein said peripheral zone is capable of blocking at least about 90% of the transmittance of UV light.
6. The contact lens of claim 2 wherein said central circular area has a diameter of between about 4 and about 9 mm.
7. The contact lens of claim 2 wherein said central circular area has a diameter of between about 6 and about 9 mm.
8. The contact lens of claim 1 or 2 wherein said contact lens comprises at least one dye in an indoor glare reducing effective amount.
9. The contact lens of claim 2 wherein said central circular area comprises dots comprising at least one dye in an indoor glare reducing effective amount.
10. The contact lens of claim 1 wherein said percent transmission is between about 75 to about 90% across the region of 420 to 700 nm.
11. The contact lens of claim 1 wherein said percent transmission is between about 80 and about 90% across the region of 420 to 700 nm.
12. The contact lens of claim 1 wherein said percent transmission is between about 75 to about 90% across the region of 450-660 nm.
13. The contact lens of claim 1 wherein said percent transmission is between about 80 and about 90% across the region of 450-660 nm.
14. A method for reducing indoor glare discomfort in contact lens wearers comprising applying to each eye of said contact lens wearer a contact lens having percent transmission at about body temperature between 70 to 90% across the region of 450-700 nm.
15. A method for reducing glare discomfort in contact lens wearers comprising applying to each eye of said contact lens wearer a contact lens comprising a central circular area centered at a geometric center of the lens and having a diameter of about 1 to about 9 mm and a peripheral zone, wherein said central circular area has, at body temperature, a percent transmission between about 70 to about 90% across the region of 420-700 nm.
16. The contact lens of claim 1 further comprising a circular area centered at a geometric center of the lens and having a diameter of about 1 to about 9 mm and a peripheral zone, and wherein said peripheral zone comprises a color print, iris pattern or a combination thereof.
17. The contact lens of claim 8 wherein said dye comprises at least one conventional colorant.
18. The contact lens of claim 1 wherein said contact lens is a hydrogel or silicone hydrogel contact lens.
19. The contact lens of claim 1 wherein said contact lens has a water content of at least about 25%.
