    Background:

    • Dark adaptation is crucial for vision, and its defects are linked to vitamin A deficiency, liver disease, and retinal degeneration.
    • Existing dark adaptation testing instruments are often impractical, costly, and inaccessible.

    Purpose of the Study:

    • To develop a practical, simple, and inexpensive test for evaluating dark adaptation.
    • To address the limitations of current standard dark adaptation testing methods.

    Main Methods:

    • A novel dark adaptation test was designed based on established standards for macular dark adaptation.
    • The test and associated equipment were developed for ease of use and accessibility.

    Main Results:
