| titleOfInvention | Automatic refracto-keratometer |
| abstract | An auto refracto-keratometer not only produces a black-and-white image for observing the alignment of eyes to be examined using an infrared illumination light but also has a color observation optical system for observing a condition of eyes to be examined using color-illumination light. The auto refracto-keratometer comprises an infrared optical system for examining an alignment and corneal curvature of eyes to be examined; a fogging optical system for relaxing accommodation of the eyes; a measuring optical system for measuring refractive power of the eyes; and a color observation optical system having a visible light source for emitting at least one visible light to the eyes and a 2-dimensional imaging device for detecting image of visible light reflected by the eyes. |
