I'm a postgraduate student in Beijing,China. I major in computer science and a lot of my work is programming. I am born with low sight, I need to use magnifying tools to see fonts on screen clearly. I use microsoft's mgnify tools on windows and use compiz's magnify plug in if on linux. I usally set the tool to magnify as three times many as the original font size. For me maginify tools is ok, the main problem is the speed,I have to move mouse to keep cursors follow the text I'm looking at, microsoft's magnify provides a option of "auto follow the text edit points",that set me from continuously mouse movement when editting or coding. But it doesn't always works because of the edit software or IDE may not support that. Magnifying tools on linux are hard to use. The KMag come with KDE has a terrible refresh rate which make my eyes unconfortable, compiz's magnifying plugs which I'm using now is OK,but has no function of auto focus(focus auto following). iOS provides quite perfect solution for me with full screen magnifying, especially on ipad's 9.7 inches screen. there auto focus is not necessary because I hardly use them to code or do other edit stuff. Android provides very little accessibility functions, only like shake feedback, which is useless for me. there is no any kind of good magnifying tools on android , not to mention advance function like full screen magnify on iOS. I used to study Qt, want to build a useful magnify tools on linux, even on android. But hardly have some progress.

许多程序员使用Emacspeak:

Emacspeak—完整的音频桌面

Hanselman最近与一位盲人开发人员进行了一次非常有趣的播客。

发明一种设备，你插入usb端口，它基本上是一块“橡胶”，它会自我修改，显示你的代码，让盲人阅读而不是听到它，怎么样?

一个开始的地方是linux项目:

该项目描述了如何获得Emacspeak(文本到语音的编辑器)，并提供了许多其他资源。

我曾经和一个人一起工作，他的视力几乎阻止了他们使用显示器——他们用屏幕阅读器软件做得很好，花了很多时间使用基于文本的应用程序和shell。

维基百科的屏幕阅读器包列表是另一个开始的地方:http://en.wikipedia.org/wiki/List_of_screen_readers

请记住，“失明”是一系列的情况——有一些人在法律上是盲人，他们可以阅读一个非常大的显示器或在放大设备的帮助下，还有一些人根本没有视力。我记得大学时的一个同学有一种可以放大书本的特殊设备，还有一种可以放大屏幕一部分的特殊软件。她正在努力完成大学学业，因为她的视力越来越差，几乎要完全消失了。

编程也有一系列的需求——有些人擅长写出大量的代码，有些人更擅长看大局和架构。我可以想象，考虑到屏幕界面所施加的难度，失明可能会增强你获得大局的能力……
