That's not true. But if it were, it would no more prove that eyes are not a sense organ than the well known experiment with arachnid hearing proves that spiders hear through their legs.He indirectly proved that the eyes are not a sense organ, one being that a dog cannot recognize his master from a picture. He should be able to, if a lightwave is bouncing off his master and striking his eye. He would wag his tail or show other signs of recognition (especially if he missed his master because he hadn't seen him in a while), but this doesn't happen.
First, you train a spider to run away when a bell rings. This can be done by administering small electric shocks when the bell is rung; After a few rounds of this conditioning, the spider will run away at the sound of the bell, even though no shock is administered*.
Next, remove the spider's legs, being careful not to kill it**
Ring the bell, and the spider won't run away. Thus (indirectly) proving that spiders hear through their legs.
