The 1.591 PC Polycarbonate Photo Grey/Brown Blue Cut UV420 Single Vision Lens integrates photochromic technology with advanced blue light filtering, offering all-day eye protection in both indoor and outdoor environments. This multifunctional design makes it especially suitable for users who frequently transition between screens and sunlight.

The lens automatically darkens to grey or brown under UV exposure while remaining clear indoors. At the same time, it blocks harmful blue light up to 420nm, helping alleviate digital eye strain and visual discomfort. The polycarbonate material ensures high impact resistance, making the lens safe and durable for everyday wear.
