If you define an eye as a biological mechanism which has a response to the stimulus of light, then Yes. Sunflowers' leaves track the sun each day. this requires a feedback mechanism which senses not only presence but also approximate direction of insolation. So I'm guessing sunflowers have minimalist eyes feeding info to an actuator mechanism (probably hydraulic) in the leaf stem.

Plants have not only eyes but feelings, X!!! That is why they respond to classical music more than to any other kind. I am sure I am not a plant, because most classical music is agitating and unpleasant to me. ;^)

<< Using that logic than would you say plants have eyes? After all photosynthesis is a chemical process driven by sunlight reacting within cells. >> Yes, in the sense that they detect light. No, if you think of eyes as specialized cells that send the gathered information to the brain to be processed. I doubt that an earthworm does that though. It seems to react wherever the light strikes. It would be interesting to scan across an earthworm with one of those pocket lasers to see how it reacts at different points on it's body. I have the laser, but I haven't seen a freekin' nightcrawler in South Texas for the 20 years that I lived here. Del
