Do you know the difference between an X-axis and a Y-axis? This little graph shows the amount light that gets through our Sun lenses. There's 0% of UVA and UVB rays getting through to those beautiful eyeballs of yours.
For those Einsteins out there that can figure the graph out, well done to you. For everyone else, the easiest way to understand is to look at the blue light range. Our lenses block all the light to the left and above the line. Eureka.
