1 Based on a visual clarity simulation of a 50mm diameter glass surface for ZEISS ClearView stock lenses with 1.60 index compared to ZEISS AS stock lenses with 1.60 index. Average of +5dpt, +3dpt, +1dpt, -1dpt, -3dpt, -5dpt and -7dpt with and without a -2dpt cylinder. Quantitative Analysis by Technology and Innovation, Carl Zeiss Vision GmbH, 2020.

2 Study participants were asked how important different aspects ('price', 'clear vision over the whole lens', 'easy to get used to', 'comfortable vision over the whole lens', 'aesthetics', 'available coatings', 'fit in the frame') for them when choosing new lenses. Wearing test comparing 1.60 ZEISS ClearView single and 1.60 ZEISS AS single in a laboratory set-up and in everyday life. N=20 participants. Technology and Innovation, Carl Zeiss Vision GmbH, 2020.

3 Measurements of lens thickness on 1.60 ZEISS ClearView stock lenses compared to ZEISS SPH single lenses with multiple prescriptions (-5dpt, -3dpt, -1dpt, +1dpt, +3dpt, +5dpt measuring without a -2dpt barrel). Up to 16% thinner center of the lens at +5.00/-2.00. Quantitative analyzes by Technology & Innovation, Carl Zeiss Vision GmbH,2020.

4 The ZEISS BlueGuard lens material builds on ZEISS UVProtect Technology, offers complete UV protection and now also blocks up to 40% of the annoying blue light.
