???? What Is AREDS 2? A Comprehensive Guide to Eye Health Supplements
As we age, preserving vision becomes a top priority—especially for those at risk of age-related macular degeneration (AMD). That’s where AREDS 2 eye supplements come in. But what exactly is AREDS 2, and how does it support eye health? In this guide, we’ll explore the science behind the formula, the differences from the original AREDS, and who can benefit most.
????️ What Is AREDS 2?
The Age-Related Eye Disease Study 2, or AREDS 2, is a clinical study that was carried out by the National Eye Institute in order to update the original AREDS formula. The goal? To find a more effective and safer eye supplement for people with intermediate to advanced AMD.
According to the original AREDS trial, a particular combination of zinc and antioxidants may reduce the progression of AMD. AREDS 2 improved upon that formula by including lutein and zeaxanthin, powerful plant-based antioxidants that help filter harmful blue light and support retinal health.
???? Differences Between AREDS and AREDS 2
If you're wondering what sets AREDS 2 apart from its predecessor, here's a quick breakdown:
| Component | AREDS | AREDS 2 |
|---|---|---|
| Vitamin A | Beta-carotene (synthetic) | Replaced with lutein + zeaxanthin |
| Vitamin C & E | Included | Still included |
| Zinc | 80 mg | Reduced to 25-80 mg in most AREDS 2 products |
| Copper | Included | Still included to balance zinc levels |
| Omega-3s | Not included | Optional addition (DHA + EPA)** in some blends |
The AREDS 2 formula for macular degeneration is considered safer—especially for smokers or former smokers—because it removes beta-carotene, which was linked to a higher risk of lung cancer in smokers.
???? Key Ingredients in AREDS 2 Eye Supplements
A high-quality AREDS 2 formula typically includes:
-
Lutein (10mg) – Supports the macula, acts as a natural blue light filter
-
Zeaxanthin (2mg) – Works with lutein to protect central vision
-
Zinc (25-80mg) – Supports retinal structure
-
Vitamin C (500mg) – Antioxidant protection for eye cells
-
Vitamin E (400 IU) – Combats oxidative stress
-
Copper (2mg) – Balances zinc and supports eye tissue
-
DHA and EPA, two omega-3 fatty acids, are optional but may promote the formation of tears and lessen inflammation.
These ingredients have been shown to reduce the risk of progression to advanced AMD in people with existing moderate to severe macular degeneration.
???? Who Should Consider AREDS 2 Supplements?
AREDS 2 is not for everyone—but it’s a game-changer for specific individuals.
You should consider AREDS 2 if you:
-
Have intermediate or advanced AMD in one or both eyes
-
Are over 50 and have a family history of AMD
-
Are experiencing early signs of vision decline or distortion
-
Want to maintain macular health with a science-backed formula
If you’re simply looking for daily eye vitamins, there are other supplements better suited for general support. But if you have AMD, AREDS 2 eye supplements are among the best eye vitamins for AMD backed by clinical research.
✅ Final Thoughts
When it comes to protecting your vision, especially in the face of AMD, AREDS 2 offers a well-researched, targeted approach to slowing disease progression. By incorporating lutein, zeaxanthin, zinc, and other key nutrients, this supplement is designed to preserve sight and improve quality of life.
Whether you’re already diagnosed with AMD or just looking to support long-term eye health, talk to your doctor about whether AREDS 2 is right for you.
