A new smartphone app accurately screens for myopia, providing a cost-effective and accessible tool for at-home vision assessment. This validated method offers reliable refractive error measurements, enhancing accessibility to eye care.

Area of Science:

  • Ophthalmology
  • Optometry
  • Biomedical Engineering

Background:

  • Subjective refraction is crucial for diagnosing refractive errors like myopia.
  • Traditional methods using phoropters are costly and require clinical settings.
  • Accessible at-home vision assessment tools are needed for early detection and management.

Purpose of the Study:

  • To validate a novel smartphone-based approach for subjective refraction, specifically for myopia screening.
  • To assess the feasibility of using smartphones as a cost-effective and accessible tool for at-home vision assessment.

Main Methods:

  • 230 healthy volunteers (7-40 years) with refractive errors underwent both conventional phoropter examination and smartphone-based subjective refraction.
  • Smartphone measurements involved moving the screen towards the eye until optotypes were clear.

  • Eye-to-smartphone screen distance was calculated using iris diameter, enabling computation of sphere, cylinder, and axis.

    • Main Results:

    • The smartphone method showed close agreement with the gold-standard phoropter examination.
    • Limits of Agreement (LOAs) for sphere, cylinder, and spherical equivalent refraction (SER) were within 1 diopter.
    • High Areas Under the Curve (AUCs) of 0.973 and 0.986 were achieved for myopia screening in specific SER ranges.

    Conclusions:

    • Smartphone-based vision screening is a valid and accurate method for refractive error assessment.
    • This technology offers a cost-effective and accessible solution for myopia screening, particularly for at-home use.
    • The approach is suitable for opportunistic and large-scale myopia screening programs, improving access to vision care.
