Product Features
1.What is the cause of fogging?
There are two reasons for the fogging: one is the liquefied phenomenon caused by the hot gas in the lens meeting the cold lens; The second is the evaporation of moisture on the surface of the skin sealed by the glasses and condensation of gas on the lens, which is also the main reason that the spray reagent does not work. An anti-fog glasses designed on the principle of electromagnet (see picture) is controlled by an electronic timing button that can adjust the frequency of demisting and the demisting strip is controlled by electromagnet. It can be used for swimming, skiing, mountaineering, diving, medical care (the anti-fogging problem of eye mask during SARS brought a lot of inconvenience to medical workers), labor protection, scientific research and biochemistry, helmet, space suit, optical instruments and meters, etc.
2.What are the advantages of anti-fog lens?
①Can block ultraviolet rays: almost completely block ultraviolet rays with wavelength below 350mm, the effect is far better than glass lens.
②Strong anti-fog effect: because the thermal conductivity of the resin lens is lower than the glass, it is not easy to produce fuzzy phenomenon due to steam and hot water gas, even if the fuzzy will soon disappear.
③Manage sudden environmental changes:Individuals going from air conditioning inside to hot, muggy conditions outside, and those going from cold outside temperatures to a heated indoor environment must contend with anti-fog lens.
④Decrease fogging frustrations:Fogged lens not only reduces a worker’s efficiency, but it also exists as a constant frustration. This frustration leads many individuals to opt out of wearing safety eyewear at all. The resulting non-compliance exposes eyes to a host of safety hazards.
⑤ Enhance vision by increasing visibility:Obviously, lens clear of fog result in clearer vision. Tasks requiring quick reactions increases a person’s need for clear visibility and reliable protection.
⑥Improve performance and efficiency:This reason for choosing anti-fog lens combines the five above reasons. Reducing fogging issues significantly increase employee performance and effectiveness. Workers stop removing their eyewear in frustration, and safety compliance increases dramatically.
3.What are the advantages of anti - blue light lenses？
Blue cut lenses feature a special coating that reflects harmful blue light and restricts it from passing through the lenses of your eyeglasses. Blue light is emitted from computer and mobile screens and long term exposure to this type of light increases the chances of retinal damage. Wearing eyeglasses having blue cut lenses while working on digital devices is a must as it may help in reducing the risk of developing eye related problems.
4. Coating Choice?
As anti-fog blue cut lens, super hydrophobic coating is the only coating choice for it.
Super hydrophobic coating also name crazil coating, can make the lenses waterproof, antistatic, anti slip and oil resistance.
Generally speaking , super hydrophobic coating can exist 6~12 months.
