China Photochromic Blue Cut Factories – Monomer Blue Block Photochromic Single Vision – YOLI Detail:
Why We Need Blue Block Photochromic Lens?
UV light and blue light are not the same thing. Normal photochromic lens can only protect our eyes from sun UV light. But blue light from natural sunlight and digital screens can still be harmful to our eyes. All invisible and partially visible light can have negative side effects to your eye health.
Blue block photochromic lenses protect against the highest energy level on the light spectrum, which means they also protect against blue light and are great for computer use.

What Situations Our Eyes Are Facing?

We are all exposed to UV (Ultraviolet) and HEV light (High Energy Visible, or blue light) with sun exposure. Overexposure to HEV light can cause headache, tired eyes and immediate and permanent blurred vision.
Extended mobile screen time at night makes it harder to go to sleep. As millennials gradually depend on their mobile devices, the generation that follows can suffer more.
