Direction of light travel

I like this graphic - but it has a quite peculiar problem: it does not inherently indicate the direction of light travel. In articles using this file, sometimes people correct description with regard to the direction of light arrival because they think that traversion of several cell layers must be certainly wrong. Actually this could be remedied with just a small twist of the picture - simply show the curvature of the eyeball. Could someone please undertake to improve his graphic in such a way?.
