Most people only think about their eye health when something goes wrong; blurry vision, eye strain, or that sudden moment when text just won’t stay in focus. But your eyes are actually one of the most powerful diagnostic tools for understanding your whole-body health. In this episode, Dr. Joseph Allen breaks down why eye exams can detect early signs of diabetes, high blood pressure, neurological disease, stroke risk, and more long before symptoms ever show up.

If you’ve ever skipped your annual eye exam because “your vision is fine,” this episode is your wake-up call.

What You Will Learn in This Episode

✅ How vision changes can reflect brain health, concussion recovery, and neurological issues

✅ The connection between eye strain, digital screens, dry eye, and mental fatigue
