Modification of common low vision devices for uncommon needs.
Journal of the American Optometric Association
|January 1, 1991
Summary
Creative modifications to low vision devices, including magnifiers, telescopes, and lenses, can address individual patient needs. These adaptable assistive technologies offer potential benefits for a wider range of visually impaired individuals.
Area of Science:
- Ophthalmology
- Vision Science
- Rehabilitation Engineering
Background:
- Individualized patient needs are paramount in low vision care.
- Standard low vision devices may require adaptation to meet specific user requirements.
Observation:
- Four categories of low vision devices were modified: hand magnifiers, stand magnifiers, telescopes, and absorptive lenses.
- Specific modifications included a +28 aspheric hand magnifier, a magnetized stand magnifier for stability, a focusable telescope on a gooseneck stand, and a flip-up frame for absorptive lenses.
Findings:
- The study details modifications to enhance the functionality and usability of common low vision aids.
- These adaptations were designed to address unique patient challenges and improve device performance.
Implications:
- The described modifications demonstrate a practical approach to customizing assistive devices for low vision patients.
- These innovative adaptations have the potential to benefit a broader patient population with visual impairments.
