1.70 High Index Glass Lenses are eyeglass lenses made from glass with a refractive index of 1.70, which is a material engineered to bend light more effectively, resulting in thinner lenses than standard glass. They are a good option for people with strong prescriptions for nearsightedness, farsightedness, or astigmatism, as the increased index of refraction allows for a more compact lens design, leading to improved comfort and aesthetics.
Key characteristics of 1.70 high index glass lenses:
- For strong prescriptions: The 1.70 High Index Glass Lenses are especially beneficial for people with high refractive errors, typically those with prescriptions stronger than +/- 6.00, to reduce the "coke bottle" effect of thick lenses.
- More reflective: Being a glass material with a high index, these lenses are more reflective than standard lenses, so an anti-reflective (AR) coating is highly recommended to reduce glare and improve clarity.
- Comfortable: The 1.70 High Index Glass Lenses reduced weight makes them more comfortable to wear, especially for extended periods, and helps prevent them from sliding down the nose.
- Aesthetics: 1.70 High Index Glass Lenses provide a more natural look by minimizing the magnification or minification of the eyes and sitting closer to the face.
