High-Index Lenses: Goodbye to the "Coke-Bottle" Effect
If you have a high prescription for myopia or hyperopia, you know how much lens thickness can affect the aesthetics of your eyewear and your facial comfort. Thanks to modern high-index lenses, the era of thick, heavy lenses is over. At Ottica IT, we select technological materials that refract light with less thickness, providing you with incredibly thin, lightweight, and aesthetically perfect lenses, regardless of your prescription.
Understanding Refractive Indices
The refractive index indicates the material's ability to "bend" light. The higher the index, the less material is needed to correct your visual defect. Here is how to choose the right one for you:
- 1.6 Index (Thin Lenses): Up to 20% thinner than standard lenses. Ideal for medium prescriptions, they offer excellent durability (perfect for rimless or semi-rimless frames) and exceptional clarity.
- 1.67 Index (Ultra-Thin Lenses): Up to 35% thinner. They are the standard choice for high myopia. They drastically reduce the eye magnification effect (for far-sighted users) or the minification effect (for near-sighted users).
- 1.74 Index (Super-Thin Lenses): The pinnacle of technology. Up to 50% thinner than base lenses. It is the definitive solution for those seeking the best possible aesthetic result with very high prescriptions, making the lens almost flat.
The Craftsmanship Precision of Ottica IT
Choosing a high index is only half the battle; the mounting process does the rest. In our laboratory, we optimize every aspect of your lens:
- Pre-mounting thickness calculation: even before cutting the lens, our technicians analyze the shape of your chosen frame to calibrate the final thickness. This allows us to guarantee the most harmonious result possible.
- Hard coatings included: high-index lenses are technologically advanced but require protection. Every thin lens we offer includes premium anti-scratch treatments as standard to preserve its durability over time.
- Asphericity for natural vision: our thin lenses are often "aspheric," meaning they are flatter. This eliminates peripheral visual distortions and reduces the unappealing eye deformation effect seen from the outside.
The Advantages of Choosing Thin Lenses
Choosing high-index lenses offers benefits that go beyond simple aesthetics:
- Unbeatable Lightness: less material means less weight. A 1.74 lens weighs a fraction of a standard lens, eliminating annoying nose marks and the continuous sliding of the glasses.
- Superior Aesthetics: high-index lenses do not "bulge" out from the edge of the frame. This allows you to choose thin metal frames or elegant designs that were previously off-limits for those with strong prescriptions.
- Total UV Protection: all high-index materials (1.6, 1.67, 1.74) naturally block 100% of UVA and UVB rays, protecting your eye health without the need for additional treatments.
