Semi-finished 1.56 Photogrey Progressive UC/HC/HMC Lens

1. Comfort & Convenience: You get a seamless transition between different vision distances, perfect for people with presbyopia or other vision needs requiring multiple prescriptions.
2. Photochromic: No need to carry around separate prescription sunglasses. The lenses adjust automatically to different lighting conditions.
3. Lightweight: Compared to higher-index lenses, 1.56 is a good balance of being thinner and lighter, making them more comfortable for all-day wear.
4. Customizable: Since they are semi-finished, the lens can be personalized to the user’s frame and prescription.
5. Aesthetic: No visible lines (like in bifocals), which looks more modern and stylish.
