装置。[Scope of Claim for Utility Model Registration] 1. A short-range optometry device, which is held within at least a certain distance by the subject during the eye exam,
Further, in a type having a large number of optometry fields through which light is transmitted, a short-distance optometry apparatus is characterized in that a fluorescent lamp 5 is provided as a light source for transmitting light through the optometry fields 3a to 3e. 2 Optometry fields 3a to 3e are provided on both the front and back sides of the near-field optometry device 1,
In addition, in order to simultaneously illuminate the optometry fields 3a to 3e on the front side and the back side, a fluorescent lamp 5 is inserted between them.
2. The short-distance optometry device according to claim 1, further comprising: a. 3. In order to illuminate the optometry fields on the front side and the back side equally, the tip portions 6a and 7a are equipped with fluorescent lamps 5, respectively.
3. The short-distance ophthalmoscopy device according to claim 2, characterized in that two V-shaped reflecting mirrors (6, 7) facing toward are provided on the sides of the fluorescent lamp (5). 4 The front and back optometry fields are arranged on rotatable disks 3 and 4, respectively,
Also, in order to replace the fluorescent lamp 5, 1 of disks 3 and 4
4. A near-field ophthalmoscopy device according to claim 2 or 3, characterized in that one of the two clamps is removably attached to the pivot shaft (8) by means of spring-loaded clamps (12a, 12b).
