Blue Light

Our blue light glasses use CR39 lenses – a high-quality lens material known for its durability, clarity, and lightweight comfort.

They are designed to filter out the blue light from screens (computers, phones, TVs), which can cause tired eyes, headaches, and poor sleep.

With our blue light filter lenses you get:

Protection from harmful blue light
Reduced eye strain and fatigue
Better sleep quality
Scratch-resistant, durable surface
Lightweight comfort for everyday use
