Wearing Behavior and Eye Length Changes in Children With Myopia Wearing Myopia Control Spectacle Lenses

The goal of this clinical trial is to learn how children with myopia aged 8 to 15 years move their eyes and heads during near-vision tasks while wearing different spectacle lenses, and if wearing myopia control spectacle lenses for one month is related to change in eye length (axial length). The main questions it aims to answer are:

1. How do eye gaze position and head movement patterns change when children wear the commercially available myopia control spectacle lenses compared with single-vision spectacle lenses? 2. Does wearing myopia control spectacle lenses for one month lead to short-term changes in axial length?

This study compares commercially available myopia control spectacle lenses with single-vision spectacle lenses to evaluate differences in eye gaze position, head movement patterns, and axial length.

Participants will:

* Attend three study visits at the Singapore Polytechnic Optometry Centre. * Wear the assigned study spectacles while performing near-vision tasks. * Have video recordings of their face collected, to evaluate eye and head movements, during the near-vision tasks.

  • No amblyopia
  • No tropia
  • No known/reported ocular pathology
  • Myopes with spherical equivalent refraction of -0.50 D to -6.00 D
  • Astigmatism of less than -4.00 D
  • Anisometropia of less than -1.50D
  • Best corrected monocular VA better than 0.10 logMAR in both eyes
  • Able to follow the protocol
  • Wearing habitual correction

  • Myopes who do not have a pair of habitual glasses

Treatment and study plan

Single Vision Lens (SVL)

Device

Standard, commercially available single vision spectacle lenses worn on-site during near vision task assessment at Visit 2 and Visit 3.

Myopia Control Lens (MCL)

Device

Commercially available Stellest® spectacle lenses worn on-site during near vision task assessment at Visit 2 and Visit 3, and worn continuously for approximately 1 month between Visit 2 and Visit 3.

Primary outcomes

  1. Change in eye gaze position

    Time frame: Visit 1 (Baseline), Visit 2 (1-2 weeks), Visit 3 (1-month)

    Eye gaze positions are derived from post-processed video recordings of participants performing near-vision tasks while wearing the study spectacles.

  2. Change in axial length

    Time frame: Visit 2 (Baseline), Visit 3 (1-month)

Other outcomes

  1. Change in head movement pattens

    Time frame: Visit 1 (Baseline), Visit 2 (1-2 weeks), Visit 3 (1-month)

    Head movement patterns are derived from post-processed video recordings of participants performing near-vision tasks while wearing the study spectacles.

  2. Change in scores of the Pediatric Refractive Error Profile (PREP) version 2 questionnaire

    Time frame: Visit 2 (Baseline), Visit 3 (1-month)

    Child-reported scores ranging from 0 to 100, with higher scores indicate better vision-related quality of life. Parent-reported scores ranging from 1-10, with higher scores indicate better vision-related quality of life.
