Visual impairment (or vision impairment) is vision loss (of a person) to such a degree as to qualify as an additional support need through a significant limitation of visual capability resulting from either disease, trauma, or congenital or degenerative conditions that cannot be corrected by conventional means, such as refractive correction, medication, or surgery. [via Wikipedia].
Some browsers have been developed especially for people with such disabilities. Features include optical character recognition, screen magnifier, screen readers, voice recognition, speech synthesisers, etc. Below I mentioned top 10 web browsers for visually impaired users.

MozBraille is a browser but an extension to transform Mozilla or Firefox to a stand alone accessible Internet browser designed for blind or partially sighted users. So with mozBraille you don’t need a third part program like a screenreader. MozBraille offers its users three displays or outputs : A Braille output on a braille terminal, a text to speech output, and a big characters view.
MozBraille is a part of the VICKIE project. The main goal of this project is to create an electronic school bag for visually impaired children. So the main output is the Braille and the less important is the text to speech because students have to listen their teacher.
Note: MozBraille is a beta version, so there are lot of features to add. At the moment, blind or a partially sighted users can’t use this software alone.
pwWebSpeak is an Internet browser designed for users who wish to access the Internet in a non-visual or combined auditory and visual way. This includes blind or partially sighted users, people with dyslexia or learning difficulties, and users who are learning new languages.
pwWebSpeak is designed to interact directly with the information on a web page, and to translate it into speech, as well as providing a magnified visual display. The user may navigate through the structure of a document based on its contents: links, headings and paragraphs, rather than having to deal with scrolling and interpreting a complex screen lay-out. The basic format used on the Web is called HTML. The intelligence built into pwWebSpeak understands the HTML constructs and automatically presents them in a logical sequence, greatly simplifying navigation of even complex documents.
Emacspeak is a speech interface that allows visually impaired users to interact independently and efficiently with the computer. Audio formatting –a technique pioneered by AsTeR– and full support for W3C’s Aural CSS (ACSS) allows Emacspeak to produce rich aural presentations of electronic information.
By seamlessly blending all aspects of the Internet such as Web-surfing and messaging, Emacspeak speech-enables local and remote information via a consistent and well-integrated user interface. When combined with Linux running on low-cost PC hardware, Emacspeak/Linux provides a reliable, stable speech-friendly solution that opens up the Internet to visually impaired users around the world.

Some techniques such as re-constructing the HTML structure, summarizing the content and filtering Ads, etc will be used. Some accessibility problem is taken into account (see Accessibility for more detail).
