Good eyesight light feeding instrument, a sharp weapon for myopia prevention and control

At present (202 1 10 25), there are three generations of optical feeding instruments with Class II medical device certificates on the market: Aierxing, Long Da and Yishiliang.

Which is the safest: The above four brands all have national Class II medical device licenses, and there is little difference in safety.

Which is the most effective: the basic principles of the four brands are the same, and they are all effective in theory. However, due to the individual differences of children, some children will have unsatisfactory results. The reasons for the unsatisfactory are closely related to the child's development, genes, the intensity of eye habits, and whether the equipment is used correctly.

3. Difference: There are only popular products that everyone is familiar with:

Yi Shiliang: The brand inventor is Professor Jiang Shunfu and Professor Zhu Ping, one of the founders of laser medicine in China. The advantage of this optical feeder is that internal and external lasers are used alternately. The theory is that when the internal laser has controlled the axial line, the external laser can be used for prevention and treatment, and can be used alternately, and Chinese and western medicine interact.

A new generation of easy-to-see light, on the basis of the original, has added three laser intensity adjustments, which is equal to the red light intensity of all optical feeders in the market.
