有关低视力和辅助技术的常见问题

了解低视力

根据 世界卫生组织(世卫组织) 和美国视光协会(AOA)的定义,低视力是指无法通过标准眼镜、隐形眼镜、药物或手术完全矫正的严重视觉障碍。低视力患者的视力会下降(在最佳矫正情况下,视力较好的那只眼睛的视力通常为 20/70 或更差)和/或视野严重缺损。不过,他们仍能保留一些可用的视力。低视力并非完全失明。低视力者在阅读、辨认面孔、看电视或安全导航等日常工作中可能会遇到困难,因此低视力辅助设备和辅助技术是保持独立的重要工具。.

视力为 20/200 是一种临床测量方法,意思是视力正常(20/20)的人在 200 英尺外就能看清东西,而视力为 20/200 的人需要在 20 英尺近的地方才能看清东西。在包括美国在内的许多国家,这一视力水平是被归类为法定失明的通用基准。.

低视力通常是由不可逆转的眼部疾病或损伤造成的。了解病因是找到正确帮助的第一步。导致低视力的常见眼疾包括

  • 老年性黄斑变性(AMD):导致中心视力出现盲点或变形。.
  • 糖尿病视网膜病变:糖尿病导致视网膜血管受损。.
  • 青光眼:导致逐渐丧失周边视力。.
  • 视网膜色素变性:一种导致夜盲症和隧道视力的遗传性疾病。.
  • 白内障(未经治疗或手术后视力不佳):晶状体混浊导致视力模糊。.
  • 视神经萎缩:视神经受损导致失明。.

这些常见的低视力原因是人们寻求低视力辅助设备和电子视频放大镜的主要原因。Zoomax 设备旨在帮助用户在这些情况下处理日常事务。.

是的、, 老年黄斑变性 是导致老年人视力低下的主要原因之一。它损害了负责中心视力的黄斑区,导致中心视力模糊或失真,影响阅读、辨认人脸和日常活动。为了应对与老年黄斑部退化症有关的低视力问题,为老年黄斑部退化症患者设计了专门的电子放大镜(如 Zoomax Snow 12它们通过可调节的放大率和对比度优化来增强中心视力细节。文字转语音(TTS)和高对比度色彩模式等功能可进一步减轻使用专为黄斑变性定制的低视力辅助设备的 AMD 患者的视觉疲劳。.

电子视频放大镜如何提供帮助

一个 电子视频放大镜 是一款功能强大的低视力辅助设备。它使用高清摄像头和屏幕,采用先进的辅助技术来放大和提高视觉清晰度。需要注意的是,它不能治愈或治疗眼疾。它的主要优点是

  • 高倍率:与传统光学放大镜相比,它的放大倍数更大、更灵活,是阅读小字体(药瓶、书籍)的理想之选。.
  • 查看模式和对比度增强:可调节对比度设置(如黑底白字、黑底黄字)大大提高了阅读舒适度,尤其适合黄斑变性患者。.
  • 远观和近观:许多型号(如 Zoomax Acesight VR 和 Snow 系列)可作为一体化低视力助视器,用于远距离任务(看电视、看白板)和近距离任务(阅读、业余爱好)。.
  • 便携性和连接性: 便携式电子放大镜 它们是购物或旅行的理想选择;有些还可以连接到电视或显示器,实现屏幕共享。.

供个人探索如何提高低视力者的生活质量、, 选择合适的电子视频放大镜 是至关重要的一步。.

Students require portable, versatile, and high-performance tools to succeed in educational environments. We recommend the 雪 12 with 雪眼雪垫.

  • 雪 12 is ideal for reading textbooks, writing assignments,and viewing distance whiteboards(when connecting with Snow Eye) thanks to its detachable foldable stand and excellent image quality.
  • 雪垫 offers a tablet-like experience and high portability, making it perfect for students who need to carry their assistive tech between classrooms while continuing the use of their personal tablets. The split-screen feature (near/distance viewing simultaneously) is deeply loved by students in the class.

For senior users, we prioritize ease of use, intuitive physical buttons, and visual comfort. The 露娜 6 和 月神 8 are our top recommendations. These devices feature have complex menus. The Luna 6 is incredibly lightweight for pocket-sized tasks like reading labels or menus, while the Luna 8 provides a larger viewing area for comfortable, long-term reading of newspapers and books without eye strain.

Professionals often need to manage high volumes of documents and integrate their assistive devices with modern office setups. We recommend the 雪垫 and our Wearable Series (such as Acesight VR Glasses).

  • 雪垫serves as a powerful workstation tool, allowing for efficient document scanning and multitasking. It can even mirror the powerpoint or any content when the professionals giving a presentation.
  • Zoomax Acesight VR glasses provide a hands-free experience, which is essential for tasks like computer work, attending meetings, or navigating office spaces while maintaining a natural posture and professional appearance. 

If you prefer listening to printed text rather than reading it, the 雪 12 和 雪垫 are our premier devices featuring advanced Optical Character Recognition (OCR) and Text-to-Speech (TTS) capabilities.

  • These devices can scan full pages of text and read them aloud in multiple languages with high accuracy.
  • Users can adjust the reading speed and volume, making these tools indispensable for enjoying long-form content like novels or complex professional reports without visual strain.
