Question #9e31c

Answer 1

From what I remember, the Cornea (the main lens of the eye) produces a real inverted image.

Explanation:

The "optics" of our eye should be the combination of the main positive lens, the Cornea, plus a fine adjustment one the Crystalline (to adapt the focussing). There is also a kind of shutter, the Iris, that opens or close according to the amount of light.
I found a picture that can help:

The image is the composition of REAL rays so it is REAL (a virtual image is produced by projections of rays analyzed by our brain to form a VIRTUAL image). As a reference have a look at the image formation of a common positive (convex) lens.

Hope it helps!
