How much percent of blue light does this lenses block?

Dear customer, our blue-light blocking lenses can effectively block 100 percent of harmful blue-light from electronic products, greatly relieve visual fatigue and provide sharper vision in front of a computer or other digital devices. The lenses also have a light brown/yellow basis, which will change the color of what you’re looking at, casting everything in a light yellow tint. Hope this is helpful. Thank you.
