Teaming Lens Science with Lens Fashion

1. The first photochromic lenses were made of
2. The first plastic photochromic lens was named
3. Molecules in these dyes switch between two molecular forms
4. ZEISS PhotoFusion lenses block UV up to
5. These chemicals produce colors by absorbing visible light when exposed to UV radiation
6. ZEISS DuraVision Premium coatings have a residual color of
7. The range of illumination levels eyeglass wearers can potentially be exposed to in a day is
8. When chromophores deteriorate and lose transparency indoors and discolor, it is known as
9. The chemical that darkened in the original photochromic glass lenses was
10. The first Photolite lenses darkened to this color
11. How many color choices are available in ZEISS PhotoFusion lenses?
12. How many color choices are available for ZEISS DuraVision Flash Mirror coatings?
13. The ANSI/ISO standard for a given material to qualify for "100 percent UV protection" is
14. ZEISS' flagship backside AR is
15. For a lens surface three times harder than the previous generation of AR coated ZEISS lenses, ZEISS uses
16. This amount of UV radiation comes directly through the front of the lens
17. The maximum residual reflection of ZEISS DuraVision premium coatings is shifted to
18. This may block some of the UV needed for photochromic lenses to become fully activated
19. ZEISS DuraVision Flash Mirrors can be applied to PhotoFusion lenses, tinted and
20. The patented chromophores used in ZEISS PhotoFusion lenses allow for excellent color control by having
