First, correct the misunderstanding. You can't judge what color film is good or bad by price. Because they have different functions.


Businesses must focus on making money. You must remember that no matter what industry it is, even if it is well done and decent, it is built on the basis of making money.


First of all, the purple film is actually the basic film layer. It has no great effect but to increase the beauty of the lens. Therefore, you can see that most glasses are blue purple or green purple.


The main differences between blue film and green film are as follows:


Difference 1: different light transmittance

In terms of light transmittance, the blue film lens is relatively weak. The light transmittance of the green film lens can reach 98.6%, while the blue film lens fabric can reach 96.8%.


Difference 2: different wear resistance

The wear resistance of blue film lens is much higher than that of green film lens. At the same time, blue film lens also has the function of preventing electromagnetic wave radiation such as computer, TV and mobile phone, which is more comprehensive in the performance of eye protection.


Difference 3: different security

Compared with the green film lens, the blue film lens can not filter harmful strong light, and the anti ultraviolet performance is relatively low. Green film lens can prevent 100% ultraviolet, infrared and a variety of harmful glare from damaging eyes. Therefore, in terms of safety performance, green film lens is better than blue film lens.


Same as the fourth: different comfort

When it comes to comfort, we naturally think of the problem of visual fatigue. The biggest advantage of green film lens is not only its high safety, but also its good comfort. This is because green is close to nature. Green light has the effect of massaging the eyes. Wearing it for a long time will not feel uncomfortable. It can relax eye fatigue and achieve the effect of nourishing and protecting the eyes. If the blue film lens is worn for a long time, it is easy to bow and cause eye fatigue, so the green film lens is more comfortable to wear than the blue film lens.


Summary:

Green film is a more advanced and complex film system than blue film. The antireflection passband is wider and flat, and the antireflection valley point is in the center of the visible spectrum (so it is green). The blue film has electromagnetic wave blocking, while the green film has some varieties and some varieties do not, but the green film has high antireflection effect and beautiful appearance. The blue film has radiation resistance and high wear resistance, but the light transmittance is poor, and the white paper will turn yellow slightly. The green film has high light transmittance, higher definition, low reflectivity and is more comfortable for the eyes (in fact, it also has anti radiation and may be more expensive).


So generally speaking, the green film has better anti reflection performance, while the blue film has better anti radiation performance. The transmittance of green film is high, up to 98.6%. The transmittance of blue film is lower than that of green film. The transmittance of blue film is 96.8%. This is a comparison of light transmittance. Secondly, the wear resistance of blue film is better than that of green film. Of course, choosing glasses should not be considered only from the color! I think the most important thing is whether the degree match is appropriate, and the accuracy of pupil measurement is more important!


Nowadays, in fact, we can't rely on color to distinguish who is good and who is bad, because there is no difference between who is good and who is bad. Now there are more than a dozen layers of glasses coating, as well as films of other colors. In contrast, the green film is the most balanced and safe. So you don't have to worry. The clerk must recommend the most suitable one for you according to your eyes and consumption ability. Just wear it well.
