About this trial
The aim of this study is evaluate and compare the mobility performance of children in daily activities while wearing single vision spectacle lenses (control) versus myopia control spectacle lenses (test).
Eligibility criteria
This trial accepts healthy volunteersQualifiers
Are between the ages of 6 and 12 years of age (inclusive) at the time of informed consent/assent.
Can achieve a corrected visual acuity of 20/20 best-corrected (or equivalent logMAR).
Have undergone a self-reported oculo-visual examination within the past two years.
Have no active ocular disease.
Disqualifiers
Have any systemic disease that affects ocular health.
Are currently using or have used, within the past 7 days, any systemic or topical medications that may impact ocular health.
Are currently using or have used any topical ophthalmic agents with anti-muscarinic properties within 7 days prior to enrollment or at any point during the study. This includes, but is not limited to, atropine, scopolamine, pirenzepine, tropicamide, cyclopentolate, and homatropine.
Have used any oral agents with anti-muscarinic properties for a chronic period (2 months or more) or short-term (within 7 days prior to enrollment). This includes, but is not limited to, gastrointestinal anti-spasmodic medications containing atropine, hyoscyamine, and dicyclomine.

Trial outcomes
Primary outcomes
Reaction time: the time elapsed between the appearance or activation of a visual stimulus and the initiation of the participant's physical response
Movement time: the time taken to complete the motor response after it has been initiated.
Response accuracy: the correctness of the participant's response to each visual stimulus, measured by the number or percentage of correctly identified or responded-to stimuli.
Secondary outcomes
Gait cycle events, such as initial foot contact with the ground and toe-off. It will be used to assess whether the type of eyewear affects natural gait patterns or mobility during peripheral vision tasks.
