Well, if the blue light didn't "pass through the cornea and lens to the retina" then it wouldn't be visible!

What does blue light do to your eyes?
Blue light has a short wavelength, which makes it very easy for it to penetrate the eyes. This means that almost all visible blue light rays can pass through the cornea and lens to the retina (the lining of the back of the eye).
