What are Hi-Index 1.74 lenses?
Hi-Index 1.74 lenses are the thinnest, flattest, and most cosmetically appealing lens ever developed and deserves the best of all technologies including the most advanced anti-reflective (AR) lens treatment.
These lenses are nearly 50% thinner than 1.50 index plastic and 13% thinner than 1.67 index, offering you the ultimate in technology and cosmetics by reducing the "eye-shrinking" effect that many high prescriptions have.
Hi-index 1.74 lenses are perfect for:
- People looking for extreme thinness and flatness
- Those desiring the latest technology
- Mid to high prescriptions to are looking for the best cosmetics
- Fashion conscious people who are up-to-date with the latest trends
- Contact lens wearers
What is the technology behind the 1.74 hi-index lens?
High index lenses have flatter curves than their lower-index counterparts for a reduced lens profile. A flatter curve, however, can cause off-axis blurred vision. To compensate, the 1.74 lens incorporates optical aspheric technology into the lens design. Not all aspherics are created equal. We have chosen only the industry's most advanced optical performance in a flat design while preserving beautiful cosmetic appeal.
