Blue block

To block blue light and provide maximum UV protection.

Blue cut lens

1、 To block blue rays and provide maximum UV protection.

2、 Blue-cut functions

a、 Block by monomer: UV powder absorbs the blue-ray

b、 Block by coating: Coating for specific spectrum reflexes the blue-ray

3、 Effective Blue-cut

a、 Lens-blue cut by monomer. usually with preset UV 420, but actually UV 410 -415, to avoid yellowish substrate color by increasing the powder.

b、 The spectrum of blue ray is between 400-500nm. UV420 blue-cut can absorb rays below 420nm completely. UV value higher than UV420 is not effective to cut, block or absorb.

c、 The spectrum of blue ray, truly heavy harmful one, is between UV415-UV450. Therefore, it’s hard to realize blue-cut precisely, and effectively.

d、 The advantage of blue-cut coating is, to make your eyes more comfortable and uneasily fatigable, as it can cut/block reflex specific spectrum, base on blue-cut by monomer

4、 Difference between Blue coating and blue-cut coating

a、 Normal blue coating

b、 Blue-cut coating

c、 Low-reflective blue-cut coating

d、 The function of normal blue coating is to penetrate, which goes against precise block as blue-cut coating.

e、 Normal blue coating is soft and reflecting dimly. Blue-cut coating, reflecting more blue-ray, looks brighter and showier. More brighter, more reflection and cut/block. The reflection rate is suggested less than 35%.

f、 Low-reflective blue-cut coating is further upgrade on regular blue-cut coating. The blue color looks pure but less-reflective bright, aim to penetrate and reflex more precisely. This one would be even more demanding on design and production.

5、 The point for reflective coating is to control the color under strict standard.
