1.74 Blue cut lens is high-index, ultra-thin lenses designed primarily for people with strong prescriptions (high myopia), improving appearance. Enhances contrast and may reduce glare, leading to a more comfortable viewing experience. The key feature is the blue light filtering technology. It selectively blocks a portion of harmful high-energy blue light emitted from digital screens (computers, phones, tablets) and LED lighting, while allowing beneficial light to pass through.
