Spending money on eye care, but no effect of eye care behavior!



In the changing times, the popularity of electronic products has a great impact on us, more and more people because of excessive dependence on electronic products, the use of eye time increases; The eyes produce a variety of discomfort symptoms, serious cause a variety of eye diseases, and the demand for anti-blue light gradually becomes larger.


But everyone always wondered that after the use of anti-blue light is always unsatisfactory, and before it is not prevented, the eyes will still be uncomfortable, and finally classified as anti-blue light concept is deceptive! The fact is that some of the merchant products are conceptual products or use detection tricks to deceive consumers.

Today we share the most easy to step on the pit of anti-blue light measurement scam!

Light scam
For people who use electronic products for a long time, blue energy retention in the eye, will cause certain damage to the eyes, with a good pair of anti-blue glasses is indeed necessary, anti-blue eye protection is a good concept, this is beyond doubt!

When going to the optometry shop to match glasses, the staff will recommend anti-blue glasses to protect the eyes, and the anti-blue test card and laser pointer will be tested on the spot to say that the lens has anti-blue light effect. The staff will put the anti-blue light test card on the horizontal table, open the laser pointer, and shine the two samples of ordinary lenses and anti-blue lenses placed on the test card. The ordinary lens covers the test card area from white to blue purple, and the anti-blue lens can always remain white, so the business says that the anti-blue lens blocks the blue light emitted by the laser, and no blue light reaches the test card, so the test card will not change color.



In fact, the laser pointer emitted is not blue light, but the wavelength range of 405±10nm of light, is the band of ultraviolet and violet light, but also the blue light of natural light, but not the blue light of the electronic screen (430-500nm). The laser pointer emits violet light, the lens can be blocked, the anti-blue light test card does not change color, can only prove that the lens has anti-ultraviolet/violet light, or anti-natural light blue light function, and can not steal the concept that the lens can also block the electronic screen blue light (430-480nm).


There are many detection methods similar to laser Pointers and anti-blue light test cards, such as the test pen test, anti-blue light tester, and even a test mold that highly simulates the structure of the human eye, they are also tested with violet light, even if the test can not prove that the lens can prevent blue light, do not believe these unreliable detection methods.


Unreliable anti-blue detection methods are prevalent, making more fake anti-blue glasses can be mixed, which aggravates the chaos of the anti-blue light market, resulting in a lack of optical knowledge more difficult to choose from the true anti-blue light glasses, can really block the electronic screen anti-blue light glasses.
