Figure 2.

Relationship between the cornea and lens transmittance for a subset of the species used in the study. Each data point represents one species, and the data for the points with a black outline were obtained from a previous study [21]. The diagonal defines the regions in which light transmittance of the eye as a whole is limited by the cornea (above the line) and by the lens (under the line). See the electronic supplementary material, S1G for corneal transmittance curves, λ_T50 values and species identification, and the electronic supplementary material, S2 for full transmittance datasets.
