Your Screening Results
Screening Complete
✅ Your screening looks excellent
All four areas screened within normal range. The biggest threat to long-term vision is silent, cumulative oxidative stress — building in the macula for years before any symptom appears. Preventive nutritional support works best exactly at this stage.

⚠️ One area to monitor
One screening area flagged a concern worth monitoring. This is the stage where AREDS2-level nutritional intervention has the strongest clinical evidence — slowing progression and preserving the function that's still working. Higher-dose carotenoids and botanical anti-inflammatories are the evidence-backed response.

🔴 Multiple concerns detected
Two or more screening areas flagged concerns. The most important step is scheduling a dilated eye exam with an ophthalmologist. Several treatable conditions produce this pattern, and early identification matters most. Nutritional support with high-dose carotenoids is appropriate alongside — not instead of — specialist care.
