Background
In medical diagnosis, a doctor often needs to enlarge his field of view by means of a medical binocular magnifier to perform various examinations, operations, or diagnosis of related conditions for a patient, etc. In order to be suitable for different users, the medical binocular magnifier on the current market mainly adopts two modes of embedded binocular magnifier and combination of myopia and magnifier.
For embedded binocular magnifier, it is necessary to redesign the optical system according to the optometry parameters of each user to suit the specific user. However, for users with different vision, it is necessary to redesign the binocular loupe optical system at the same working distance. Furthermore, for the embedded binocular magnifier, the cylindrical lens correction cannot be realized, so that the visual comfort of a user is reduced. In addition, if the vision of the user changes, the magnifying glass needs to be replaced according to the vision condition, and the existing embedded binocular magnifying glass is difficult to replace once the magnification of the magnifying glass is determined because the magnifying lens barrel is directly adhered to the spectacle lens.
For the binocular magnifier combining the near vision mirror and the magnifier, as the correcting lens is external (positioned between the cornea and the ocular lens), the distance between the correcting lens and the face of a user is too short, so that the correcting lens is easy to be polluted and fogged to cause unclear visual field, and the using effect is affected. In addition, similar to the embedded binocular magnifier, it has a defect that the magnifier is difficult to replace once the magnification is determined.
