Manual keratometer BL-8002

tabletop

Since the corneal refractive power accounts for 2/3 of the total refractive power of the human eye, the curvature measurement of the cornea can understand the total refractive power of the human eye. At the same time, since most of the human eye astigmatism comes from the cornea, the corneal curvature readings are very good in terms of optometry and prescription analysis. important. In the computer optometry, the corneal curvature measurement has been mentioned Product Description In this section, we will introduce the optical keratometer and its application. The keratometer uses the reflection properties of the cornea to measure its radius of curvature. The features of the keratometer are as follows: ①The eyepiece can be adjusted so that the examiner's eyes can be focused clearly. ②The jaw rest and headrest can be adjusted so that the subject’s head position can be fixed during the inspection; the handle can be moved up and down to adjust the height of the instrument so that the subject’s eyes are on the same level. ③Two degree wheels can measure the curvature of the two principal meridians. ④) There is an axial scale, which can express the position of the two main meridians, and the entire barrel of the curvature meter can be rotated. ⑤The cursor is projected to the cornea of the examinee; the focus control handle can be moved back and forth to focus the cursor on the cornea of the examinee clearly.
