I went to the optometrist, the optometrist is not desktop but handheld, novelty and comfortable, do not have to pestle neck for a long time. However, the feeling is not allowed, may I ask this device legal compliance? We are very happy to have someone ask questions about our products ~ owner you are talking about handheld vision detector, the country currently only have us, we are "Mafu glasses" ~

Like you said that the optical inaccuracy does not exist, the working principle of the hand-held optometrist and your common desktop equipment, that is, the class of China's Class II medical device optometrists are similar. Medical device optometry is similar, are the use of infrared light source and automatic fog vision device to achieve the purpose of relaxation of eye adjustment, the use of photoelectric technology and automatic control technology to check the refractive error.

And optometry can not replace the photographer optometry and lens correction technology, only to the manual optometry to provide reference.
