How can Invisible Woman see?

Question

Marvel.com says Sue Storm has a power to bend all wavelengths of light and this way she becomes invisible.

Sue can render herself wholly or partially invisible at will. She can also render other people or objects invisible, affecting up to forty thousand cubic feet of volume.

She achieves these feats by mentally bending all wavelengths of light in the vicinity around herself or the target in question, and she somehow does this without causing any visible distortion effects; she also somehow directs enough undistorted light to her eyes to retain her full range of vision while invisible. - Source

The quote above also says she somehow does this without losing her eyesight.

Are there any references in the comics that explain how she does this? Or did they just jump into the story without giving somehow logical answer to that?

Answer 1

If she bind the rays of light to become invisible, it means that she has to bend every single one that whose direction go through her body (or the object she renders invisible) in order to avoid her body and then bend it exactly at the same angle and line it was comming initially (and so for every photon and at the speed of light).

So it must be easy to select a part of the photons that are going into her eyes and don't divert them so they hit her eyes (she is already calculating photon trajectory and diverting them twice and does so faster than light). So her eyes could appear like a little blur or a little darker spot, but could be nearly invisible if she only let a fraction of the original light...

So this power is somewhat physically possible if you accept FTL thinking and light bending ^^

Answer 2

Perhaps she only bends reflected light, outbound from hitting her body. She wouldn't be emitting and radiation to observe but she could still observe the incident light. On the other hand it's foolishness to try and apply science to Gold & Silver Age comic books, there's no reason not to call it magic.
