Water Properties of Soft Contact Lenses: A Comparative Near-Infrared Study of Two Hydrogel Materials

Figure 5

Principal component (PC) loadings plotted as a function of wavelength. This plot shows the importance of certain wavelengths in the respective spectral pattern of each PC. First two PC factors described 98,6% of the variations in the dataset with PC1 factor (blue line) describing 94,3% and PC2 factor (red line) describing 4.3%.
