What is Hi-Index?
- Lenses are made using different densities. When a material is more dense, it means it has a higher index.
- Hi-index lenses are made so the lenses are thinner for higher powers.
- I recommend Hi-Index option for thinner lighter lenses especially when the sphere (2) section of your prescription is higher than + 3.50 or lower than - 3.50.
- Hi-Index lenses look better, are thinner and lighter.
