🧠 What Are High Index Lenses?
High index lenses are advanced optical lenses designed to bend light more efficiently. This means they require less material to correct vision, resulting in:
- Thinner lens profiles
- Lighter weight for improved comfort
- Better aesthetics — no thick lens bulge
They are particularly ideal for moderate to high prescriptions, especially for wearers seeking lighter, more attractive eyewear without compromising clarity.
🔬 Index Numbers Explained
Each lens material has a refractive index — the higher the index, the thinner the lens at the same prescription strength. Here's a quick breakdown:
| Index | Description | Typical Usage |
|---|---|---|
| 1.50 (Standard) | Basic, low cost | Low prescriptions |
| 1.60 | Thin & lightweight | Moderate prescriptions |
| 1.67 | Super thin | Strong prescriptions |
| 1.74 | Ultra thin | Very strong prescriptions |
At POG, we typically recommend 1.67 or 1.74 for anyone with a sphere of ±4.00 or stronger.
✨ Why Choose High Index Lenses?
✅ Thinner Profile
No more thick “milk bottle” lenses — high index optics maintain a sleek edge.
✅ Lighter Weight
Ideal for full-time wearers — less pressure on your nose bridge or ears.
✅ Frame Compatibility
More flexibility in choosing stylish frames (including rimless and semi-rimless options).
🛡️ Pair with the Right Coating
Your investment deserves the right protection. High index lenses work best when combined with:
- Anti-Reflective Coating (like EverClear Plus)
- UV Protection
- Hydrophobic + Scratch-Resistant Layers
All high index lenses at POG come with EverClear Enhanced MAR as standard.
🎯 Best For:
- Anyone with a prescription stronger than ±3.50
- Wearers who want lightweight, discreet lenses
- People who wear glasses all day, every day
