Figure 1 : 

Spectral transmission of common pig lens. Mean and confidence interval (max and min) of three lenses.


Figure 2




Figure 2 : 

Spectral transmission of a pig lens when it was irradiated with ultraviolet A+B radiation at an intensity of 10j/cm2 and with three different exposure times: 5, 10, and 20minutes, corresponding to T5, T10, and T20. T0 with no irradiation.

Figure 3 : 

Spectral transmission of a pig lens when it was irradiated with ultraviolet A+B radiation at an intensity of 20j/cm2 and with three different exposure times: 5, 10, and 20minutes, corresponding to T5, T10, and T20. T0 with no irradiation.

Figure 4 : 

Photographs of pig lenses taken with a slit lamp using an orange background for a clearer image. a: freshly removed lens; b: lens irradiated for 20minutes at an intensity of 20j/cm2; a low density anterior subcapsular cataract (ASC) can be seen (white arrow); c: a dense ASC cataract produced by radiation at 20j/cm2 intensity for an exposure time of half an hour.
