    A low-cost, head-mounted illuminator provides focused light for reading, benefiting individuals with low vision. This device offers a practical solution for improved reading accessibility for the visually impaired.

    Area of Science:

    • Ophthalmology
    • Assistive Technology
    • Biomedical Engineering

    Background:

    • Reading difficulties are common among individuals with low vision.
    • Existing assistive devices may be expensive or cumbersome.
    • The need for accessible and affordable reading aids is significant.

    Observation:

    • A novel head-borne device was developed to illuminate reading materials.
    • The device delivers a bright, focused light directly onto the text.
    • It functions effectively even at very close reading distances (1-2 cm).

    Findings:

    • The head-borne illuminator is inexpensive to produce.
    • It has been successfully used by a visually impaired individual for two years.
    • The device significantly enhances the visibility of reading material.
