China Polycarbonate Sunglass Lens Companies – 1.59 PC Blue Block Photochromic Single Vision – YOLI

Why Polycarbonate Lenses?

Thinner and lighter than plastic, polycarbonate (impact-resistant) lenses are shatter-proof and provide 100% UV protection, making them the optimal choice for kids and active adults. They’re also ideal for strong prescriptions since they do not add thickness when correcting vision, minimizing any distortion.

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.

With a standard optimal lens, both UV and HEV lights can reach your eye. Not only do Photochromic Blue Blockers block harmful HEV blue light, they also darken in the sunlight, and return clear inside. Everything you need in one pair!

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.

Three Main Strengths of Blue Block Photochromic Lens

Blue Light Fliter
Just like our regular blue light lenses, our blue block photochromic lenses are also engrained with a blue light element in its raw material.

Rapid Transitioning
Our blue block photochromic lenses change from light to dark when exposed to daylight. Regular blue light lenses when you’re indoors, then straight to sun lenses when you step outside.

100% UV Protection
Our lenses come with UV-A and UV-B filters which block 100% of UV rays from the sun, so you can concentrate on important things.
