Semi-finished 1.56 Photogrey UC/HC/HMC Lens

1. Photogrey/Photochromic Technology:
● Automatic UV Protection: Photogrey lenses darken in response to UV light, providing a built-in sunglass effect when outdoors. This helps protect your eyes from harmful UV rays, reducing the risk of eye strain and long-term damage.

● Convenience: You don’t need to carry separate pairs of glasses for indoor and outdoor use. The lenses adjust to the lighting conditions automatically, making them very convenient for people who are frequently moving between indoor and outdoor spaces.

2. 1.56 Index:
● Lightweight: Lenses with a 1.56 refractive index are thinner and lighter than standard lenses, especially for moderate prescriptions. This makes them more comfortable to wear for long periods.
● Good for Mild to Moderate Prescriptions: A 1.56 index strikes a balance between cost and performance, making it a great choice for those who don’t require extremely high prescriptions but want a lens that’s thinner than regular lenses.

3. Semifinished Lens:
● Customizable: A semifinished lens is one that is only partially completed, allowing an optician to further shape it to suit your exact prescription and frame style. This provides a more personalized and precise fit for your optical needs.
