Photochromic Blue Cut & Blcok Lens

Photochromic blue light blocking lenses are lenses that combine photochromic properties (darkening outdoors like sunglasses, becoming clear indoors) and blue light blocking (filtering harmful blue light from electronic screens). They effectively reduce eye strain and provide all-day protection against UV and blue light in various lighting environments, making them suitable for modern people who need to balance outdoor activities and electronic device use. Usage Scenarios:
Commuting/Outdoors: Provides clear blue light blocking glasses when working or engaging in indoor activities; automatically changes color to sunglasses outdoors to protect eyes from strong light and blue light damage.
Electronic Screen Use: Blocks harmful blue light in front of computers, mobile phones, and other devices, reducing symptoms such as dry eyes, eye strain, and eye fatigue.
