See how streetscape exposure might influence kids’ vision and perceptions

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Researchers will use a virtual simulation of street environments to study how exposure to different streetscapes influences visual perception and psychological perception in children with myopia and in emmetropic peers. The study uses eye-tracking to measure attention and visual processing while children view simulated streetscapes. Participants include 6-18 year-olds with myopia or emmetropia, with specific inclusion and exclusion criteria to ensure safety and valid measurements. The aim is to identify streetscape features linked to perceptual changes, informing potential environmental strategies for eye health and urban planning. This is an observational study focusing on perception rather than a clinical intervention for treatment.

Who can join: the full rules

Inclusion Criteria:

\- 1: Myopia group: (1) informed consent obtained; (2) children aged 6-18 years; (3) no contraindications for wearing the eye-tracker (e.g., high astigmatism, head/neck injury); (4) myopia already present in at least one eye (spherical equivalent ≤ -0.50 D).

2: Emmetropia group: (1) informed consent obtained; (2) children aged 6-18 years; (3) no contraindications for wearing the eye-tracker (e.g., high astigmatism, head/neck injury).

Exclusion Criteria:

\- 1: Myopia group: (1) high myopia in either eye (spherical equivalent ≤ -6.00 D); (2) any ocular pathology other than myopia (strabismus, amblyopia, congenital cataract, juvenile glaucoma, retinal disease, etc.); (3) systemic disorders that may affect vision or visual development (e.g., diabetes); (4) anisometropia \> 1.00 D or astigmatism \> 2.00 D in either eye.

2: Emmetropia group: (1) myopia or hyperopia in either eye (spherical equivalent ≤ -0.50 D or ≥ +0.50 D); (2) any ocular pathology (strabismus, amblyopia, congenital cataract, juvenile glaucoma, retinal disease, etc.); (3) systemic disorders that may affect vision or visual development (e.g., diabetes); (4) anisometropia \> 1.00 D or astigmatism \> 2.00 D in either eye.
