A recent article in the Ophthalmology magazine introduced a case of magnetic implants for the treatment of the nystagmus, the first report of an implant to control the eye movement. Researchers from University of London and University of Oxford implanted a magnetic device into the eye and successfully cured a more than 40 year old nystagmus patient. The specific method is to implant the magnet on the bottom of the orbit and to suture another magnet to the extraocular muscles that control the movement of the eyeball. Because the force of the magnet is just good, the magnet can control the movement of the eyeball involuntarily, and it will not overly affect the normal movement of the eyeball.

As a magnet buyer, you may have purchased many times and do not know how to distinguish the quality of the magnet. Xiaobian today stands on a neutral point of view about how general magnets identify quality. In terms of size, check the tolerances required for the size, some of the outer diameter and the thickness of the negative tolerance are more serious, and from the appearance surface treatment, if the surface color is very poor, even the edge collapse angle that needs to be careful, and then the surface, if there are a lot of small edge missing angle, also need to be paid attention to.
