Low Vision Devices

At the center, we prescribe and dispense a number of low vision aids in addition to the professional skills training. Our inventory of low vision devices includes magnifiers, telescopes, spectacle microscopes, non-optical devices, illumination sources, contrast enhancement aids, and electronic video magnifiers.

Magnifiers are commonly prescribed for moderate vision loss. Hand-held and stand types (illuminated and non-illuminated) are relatively inexpensive, portable, and are sufficient for short and moderate length reading needs. The disadvantage is a narrower field of view compared to ordinary spectacles. However the benefit of improved reading outweighs that disadvantage.

Telescopes are generally used for enhancing distance visual tasks (watching TV, concerts, sporting events, etc.). Occasionally, telescopes can assist near vision tasks. Telescopes can be monocular (one eye) or binocular (both eyes) and can be hand-held or spectacle mounted. A recent addition to the telescope line is one that has auto-focusing capability, providing hands-free use.

Electronic Video Magnifiers provide the user with a wide range of magnification and contrast enhancement in one easy-to-use unit. Closed Circuit Television has been the mainstay in this category. Newer systems allowing portability and wearability have only recently become available.

Computer Software for the Visually Impaired allows the computer user to enhance the visibility of computer applications by enlarging the size of the screen contents. Other capabilities include synthesized speech for the profoundly impaired or blind.

Additional Resources and Referrals include local and state agencies servicing the needs of the visually impaired. These agencies provide in-home evaluation and training for activities of daily living or assistance with education and employment opportunities. We provide each patient a resource package supplying information on large print sources, books on tape, support groups, local and national organizations.
