To access the data, click or select the words “Appendix 1.” Sequential lens images at different temperatures show a recovery course from a cold cataract in a P14 B6WT lens (A) and a P14 129WT lens (B). Representative lens images at 4 °C, 11 °C. 19 °C and 25 °C were subjected to quantitative measurements by image J scans along the equatorial line (C for B6WT and D for 129WT) from the left surface to the right surface, and the lens diameter was arbitrarily normalized to 2. B6WT lens fully recovered its transparency at 37 °C and 129WT lens became clear at 25 °C.
