盲人包括生活盲(视力不足0.02)和科学盲(视力光感为“0”)。盲人助视器是随着现代科学特别是电子科学的发展而出现的。它使盲人失去的视觉信息重新获得,故又称人工视觉。这种视觉是通过触觉、听觉乃至皮层植入器而产生的。目前纳入实用的盲人助视器有: 1.声纳眼镜。这是模拟蝙蝠夜间可发射并回收超声波而制成的。即在眼镜架
Blind people include blindness (less than 0.02 for eyesight) and blind for science (0 for sightight). The blind aids appear with the development of modern science, especially electronic science. It regains the visual information lost by blind people, so it is also called artificial vision. This vision is generated by tactile, audible and even corticotactic implants. Currently included in the practical blind aids are: 1. Sonar glasses. This is made by simulating bats emitting and recovering ultrasound at night. Namely in the glasses frame
