一般人成年后正常视力为1.01.5,我国科学家的一项研究表明,成年人的视觉神经系统仍有相当的可塑性,经过仪器矫正和科学训练后,可获得2.0及以上的“超视力”。该项研究是由中国科大中科院脑功能与脑疾病重点实验室周逸峰小组与成都光电所张雨东小组合作完成的,他们创造性地将视知觉学习与人眼自适应光学技术相结合。他们做了这样的对比实验:两组被试者进行同样对比度检测任务的知觉学习,其中一组做了人眼高阶像差的矫正,有较理想的人眼光学系统,另一组没做高阶像差的矫正,是普通人眼光学系统。结果发现,矫正过的小 Normal adult visual acuity after 1.01.5, a study by our scientists shows that the adult visual nervous system is still considerable plasticity, after instrumental correction and scientific training, you can get 2.0 and above . The study was conducted by Zhou Yifeng, a key laboratory of brain function and brain disease at the Chinese University of Science and Technology (CAS), and Zhang Yudong, a team at Chengdu Optoelectronics Research Institute. They creatively combined visual acuity learning and human ophthalmic adaptive optics. They did such a comparison experiment: two groups of subjects to perform the same contrast testing task of perceptual learning, one of them to do high-order human eye aberration correction, there is a better system of human ophthalmology, and the other did not do High-order aberration correction, is the ordinary human optics. The results showed that the corrected small
