80% harmful light filtration, UCN i-Blackboard gets eye protection certificate

With the development of education information, smart educational devices have stepped into more and more classes. Eyesight safety caused media’s and parents’ concerns. According to a report, recently a parent wrote a letter to school and suggest reduce using projectors in classes because he is worrying the bad contrast of projector, unclear display will cause children’s bad eyesight.

Does projector really affect eyesight? Is there a smart blackboard which can protects eyesight? Is traditional blackboard safe? With above questions, we can analysis and discuss in a scientific way.

The projector really affects eyesight.
 

In the classroom of using projectors, the images students see is the reflected light of projection. And the teachers need to draw window blind to reduce environment light of the classroom, which will reduce the brightness of the desktops. Constant switch of dark desktop and bright screen will easily lead to eye strain. And after some time usage, the aging of panel, camera dust accumulation will cause blurring of projection. If this situation keeps for a long time, it will bad for eyesights.

UCN i-Blackboard can filter 80% harmful light

Since the projector has some bad effect to students’ eye-sights, is there a product which contains its function but protect eye-sight at the same time? Recent years, UCN i-Blackboard has stepped into many schools in Beijing, Shanghai, Nanjing, Suzhou, and are well received. For the reasons, it is not only because the strong function of the blackboard, but also because it can protect eyesight. We learn from TMC that UCN i-Blackboard has officially got product certificate of eyesight protection. Through testing, it can effectively filter harmful light, including 79.89% ultraviolet ray, and 81.07% infrared ray. It is anti-dazzling and anti-reflection.

UCN i-Blackboard is a smart interactive teaching equipment. It puts touch foil under tempered glass. Combined touch foil, lcd display, computer host together and contains all the functions of projectors and other functions like touch interactions, chalk-writing which projectors and infrared white board cannot realize. The tempered glass of blackboard surface applies nano compound plating technology. It is not only easy for writing but also has two technology advantages of highlight filtration and anti-dazzling.

Highlight filtration technology will filter harmful light which is bad for eyesight, making images softer. Anti-dazzling technology will make blackboard surface unable to form reflection image and will not affect image effect. Applying LED backlight screen and HD 1080P display makes all the students in the classroom see clearly. 

Serious dust and reflective blind area for traditional blackboard

Many people think that traditional blackboard will not affect eyesight. But through our research, we find there are blind area for traditional blackboard. If the classroom is too dark and the teaching time is too long or writing too intensive, it will also affect eyesight. Meanwhile, the dust of traditional blackboard is very serious and has inevitable influence to teachers’ and students’ health. It has many disadvantages like not support multi-media, boring teaching contents and will inevitably be replaced eventually. 

The survey shows that in our country there is about 5 hundred million myopia, in which the teenagers take a big part of it. For primary students, the myopia rate is above 30%, for middle school students above 70%, for college students above 90%. It is imperative to eliminate the teaching equipments which affect students’ eyesight and make students own bright eyes with new technology products.
