Material: High-Index Plastic
Index of Refraction: 1.67 (Thinner than 1.61 and polycarbonate)
Density: Lightweight but slightly heavier than polycarbonate
Photochromic Technology: Lenses darken outdoors when exposed to UV light and return to clear indoors.
Ultra-Thin & Lightweight: Up to 40% thinner than standard plastic (CR-39), making it ideal for strong prescriptions.
Aesthetic Appeal: Reduces edge thickness, preventing the "bulky" look in higher prescriptions.
Superior Optical Clarity: Provides sharper vision with minimal distortion compared to polycarbonate.
Anti-Reflective Coating Recommended: Due to its high refractive index, an AR coating is strongly recommended to reduce glare and reflections for better clarity.
Delivery Time: Shipping times for lenses vary depending on the retailer or optical store. Typically, lenses can take from 5-10 business days to ship, especially if they're customized or require specific coatings.
Packaging: Lenses are typically shipped in protective cases or boxes to avoid damage during transit.
