自1859年Bowman发明了检影验光技术以来,经过100多年的发展已日臻完善。但检影验光技术难度较高,其读数不能做为验光处方,必须配合主觉验光,进行精确测定,再配合双眼平衡和融合功能测试,才能确定验光处方。 难点一:检影验光是用检影镜寻找验光师和患者眼之间的共轭焦点。找到中和点时在患者眼前添加的镜片光度,实际上包括了四个部分:患者屈光不正、患者的调节、验光师的屈光不正、验光师的调节。只有排除后面三部分才可能得出患者屈光不正。患者的调节可以通过散瞳排除,验光师最好是正视眼或其
Since 1859 Bowman invented the technology of retinoscopy, after 100 years of development has been improved. However, retinoscopy technology is more difficult, the reading can not be used as a prescription, must be with the main optometry, accurate determination, and then with the balance of eyes and fusion function test to determine optometry prescription. Difficulty one: retinoscopy optometry retinoscopy is to find the conjugate focus between optometrists and patients. The lens luminosity added in front of the patient when the neutralization point was found actually consisted of four parts: patient refractive error, patient adjustment, optometrist refraction, optometrist adjustment. Only by excluding the back of the three parts may come to patients with refractive errors. The patient’s conditioning can be ruled out by mydriasis, optometrists are the best face to face the eye or its
