Synopsis: This information reviews a range of computer screen magnifier software programs designed to enlarge on-screen content for people with low vision, including conditions such as macular degeneration and reduced visual acuity. The article explains that screen magnifiers interface with the computer's graphical output to present enlarged views, with magnification levels commonly ranging from 1x up to 16x, and notes that higher magnification reduces the visible portion of the original screen. It then profiles individual products including Magnifying Glass Pro, SeeIt Magnifier, ZoomText, BigShot Screen Magnifier, Supernova Reader-Magnifier, Lunar Screen Magnifier and The Magnifier, outlining their distinguishing features so visually impaired users, seniors, caregivers and assistive technology specialists can compare options when selecting magnification software.

At a Glance

Topic Definition: Computer Screen Magnifier

A computer screen magnifier is a category of assistive technology software that interfaces with a computer's graphical output to present an enlarged view of part or all of the display, supporting people with low vision conditions such as macular degeneration, reduced visual acuity and other forms of partial sight loss. Magnifiers typically offer adjustable zoom levels - commonly between 1x and 16x, with some products extending considerably higher - along with options such as lens, split screen or full screen viewing, color and contrast adjustment, cursor and focus highlighting, and tracking of keyboard and mouse activity. More advanced packages combine magnification with screen reading, speech output and Braille support to address a broader spectrum of visual impairment needs.

Introduction

Computer Screen Magnifiers Suitable for Visually Impaired

A screen magnifier is software that interfaces with a computer's graphical output to present enlarged screen content. It is a type of assistive technology suitable for visually impaired people with some functional vision such as macula degeneration or loss of acuteness. Ranges of 1- to 16 times magnification are common with screen magnifiers. The greater the magnification the smaller the proportion of the original screen content that can be viewed, so users will tend to use the lowest magnification they can manage.

Main Content

Magnifying Glass Pro

Magnifying Glass Pro is a very well presented package and achieves with ease what many other similar products fail to do. Well worth the small price asked for such an excellent product. (Disabled World is not affiliated with this product)

Specifications:

The Auto-switcher, which enables you to associate individual applications, windows, and screen elements with specific user-defined Profiles (group of Glass settings). As the "target" changes (e.g., you switch applications) the Auto-switcher applies the appropriate Glass settings automatically, based on the defined Profile association, with no interruption to your productivity.

No restrictions on how you can use Magnifying Glass Pro. You control the size and position of the Glass - it can occupy the entire screen, or a smaller, user-defined area. It can even extend beyond the edges of your screen to move to a second monitor. You can quickly and easily apply a myriad of effects to enhance your viewing experience and solve the sophisticated needs of any text or graphics-based project.

SeeIt Magnifier

Seeit is a new magnifier for the pc and is compatible with Windows XP and Vista. You can magnify anything on your screen by up to 32x, whether it be the whole screen or just an area of your choice.

You can zoom in for easier viewing of videos, E-mails or anyone of your favorite programs. It is controlled by an easy to use control panel which enables you to magnify by strip or lens anything on your screen. Enabling you to set a resolution that fits your needs.

Compared to other similar products it comes at a reasonable price.

Zoomtext

Zoomtext does not only zoom and enhance all that is on your screen, it can make you hear everything you are doing in all of your applications. It will read for you your documents, E-mails and web pages so that you do not have to force your eyes to do it yourself. Zoomtext will provide a high definition image of text at any magnification level making it easier then ever to recognize what you are reading. It also comes with built in productivity tools that will make everything quick and easy to find. All of this can also support dual monitors to further expand your view with two computer screens. You can use the second screen to share a magnified or unmagnified view of your desktop.

Features:

Just plug in the ZoomText USB drive and ZoomText automatically starts up. If ZoomText is not installed, the friendly setup program is launched and you'll be up and running in minutes.

Zoomtext is compatible with Windows XP - 2000 and Vista.

Insights, Analysis, and Developments

Editorial Note: Choosing the right screen magnifier is rarely a question of finding the highest magnification number on a feature list - it is about matching the tool to the way a person actually reads, works and navigates a computer. Some users will benefit most from a simple, inexpensive lens-style enlarger, while others need the integrated speech, Braille and document reading features found in full screen reader and magnifier combinations. Trying software in real working conditions, with the documents, websites and applications used every day, remains the most reliable way to decide which combination of magnification style, color handling and tracking behavior actually reduces fatigue and supports comfortable, sustained use.
