Three eye-opening factoids from the RealAge doctors . . .

First, when it comes to your eyes, Popeye trumps Bugs Bunny. Although carrots are good for your eyes, they're not as powerful as spinach. Research shows that more protective benefits come from the lutein found in spinach than the beta carotene found in carrots. That's what's up, doc. More . . .

Second: Exercise isn't just good for your heart and waist size; 30 minutes of fitness also reduces eye pressure by 20 percent. Deep breathing also can help reduce eye pressure by helping drain the lymphatic system.

Third: Visual "floaters" usually aren't dangerous. Although those little black dots you see can be disturbing the first time you notice them, they're actually harmless -- unless they're increasing in frequency. The specks float around in the vitreous fluid in your eyes and are usually caused by some form of trauma (like a car accident) or from a lifetime of optical wear and tear, including straining and rubbing your eyes.
