Mid-index lenses are slimmer and lighter than standard plastic types. Slightly stronger prescriptions for farsightedness typically require a thicker lens. Mid-index lenses minimize thickness in these prescriptions and are generally more affordable than high-index plastic materials.
High-index lenses are typically more expensive than standard plastic and mid-index varieties, but offer a wider choice of frames for people with stronger prescriptions, since the lenses are not bulky. Wearers benefit from a crisp, clear field of vision and comfort, even during prolonged use. When treated with a no-glare coating, high-index lenses sharpen sight considerably—especially at night.
