with low vision often require text materials in large print and/or high contrast,
which makes the text easier to read. Strategies can include magnifying text so
that it's larger, to moving closer to the source of the text. Several products
can assist in typical class activities. Many useful Assistive Technology tools
can be found in local stores due to their Universal Design features (such as large
button calculators). There are also several excellent online Resources
of products designed for students with low vision.
The examples can be
used by students in the classroom for different activities.

Braille labels, which can be used in a variety of ways in the classroom. (APH
impaired students can learn to use their residual vision more efficiently by training
with APH's Light Box. Materials are used with it to promote basic visual skills,
eye-hand coordination and simple matching tasks (APH Photo)

Reading and writing activities are intricately related.
A child learns to write what he has read. Here are some low-tech Assistive Technology
solutions to support a child's visual ability.
Lighting can greatly impact a child's ability to see and participate
in classroom activities. Don't forget to address lighting and page glare (see
below) when setting up a learning environment for a student.
and lighting are often the key to improved reading. However, what works is very
individual. Some students find reading is easiest with very bright directional
light illuminating the page. Other students with an identical eye condition, however,
prefer low levels of diffused light. Students often prefer fluorescent lights.
Check with the child's Teacher of the Visually Impaired (TVI) for information.
Common white paper often reflects a significant glare, which can
make the reading process more difficult. Try covering the page with a transparent
colored plastic or an acetate sheet, available at stationary stores, to tone down
the brightness. Experiment to find the best color for a student.
Large text publications for no, minimal or commercial
cost can be found at several sites. You may be required to register; some offer
several format options.

students with low vision who benefit from large print, a video magnifier (sometimes
referred to as a CCTV,) may provide the best access to diagrams, graphs, maps,
math, forms and other print material not stored on a computer. Most are stand-alone
devices with a moveable table, a camera with a zoom lens, and a monitor. Material
is placed on the moveable table under the camera and the image is magnified and
displayed on the monitor. There are also portable models that use hand-held cameras
or cameras that can use a TV screen as the monitor. For individuals with low vision,
careful consideration should be given to providing a full color model as many
diagrams and maps incorporate color that impart information. On a black &
white model, that information may be lost.
Look for special features
of video magnifiers including:
- Magnification up to 60 times
contrast white on black or black on white
- Moveable line markers to help
keep reading position
- Full color
- Selectable foreground & background
- Split screen capability when computer monitor is used as the monitor
