Definitely, but there are several buts.

There some invisible aquatic animals in practice. They are transparent, with a few coloured spots in strategic places, and their eyes are small and camouflaged. In the field they are invisible to most of their potential enemies.

Then again, if the retina only has to intercept light that is invisible to the seekers of invisible creatures, for example if it only has to see UV or infrared, then the creature could be invisible to X-rays, "visible" light and microwaves.

What about a retina that is split into tiny sub-retinae that one could not see without a lens?

Also, if it is possible to direct light round the retina, one could achieve near invisibility.

Finally, I have seen examples of camouflage that, though they did not confer theoretical invisibility, were so good that I could not see the whole animal without picking it up. What about those that I did not see at all?

Theoretical perfection is seldom a useful concept.

As far as I can see, anyway...
