Area of Science:

  • Ophthalmology
  • Optometry
  • Vision Science

Context:

  • Accurate near visual acuity assessment is crucial for daily tasks and professional suitability.
  • Existing methods may lack standardization for near vision examinations.
  • The need for reliable tools to evaluate visual function at close distances is recognized.

Purpose:

  • To present a standardized optotype model for near visual acuity testing.
  • To introduce a system for estimating near visual acuity for professional selection.
  • To facilitate the evaluation of individuals with varying visual acuity, including those with impairments.

Summary:

  • This research introduces a standardized optotype for near vision testing at 40 cm.
  • The model incorporates Jaeger notation (1-16) and a standardized point system (3-36).
  • It enables precise near visual acuity estimation for both normal and visually impaired individuals, aiding professional selection.

Impact:

  • Improved accuracy in diagnosing and managing visual acuity deficits.
  • Enhanced ability to determine occupational suitability for individuals with visual impairments.
  • Provides a validated tool for optometric and ophthalmologic practices globally.
