Tokyo, Oct. 1 -- UMIN Clinical Trials Registry (UMIN-CTR) received information related to the study (UMIN000063023) titled 'Short-term clinical study to evaluate changes in ocular reaction under various visual conditions' on Oct. 1.

Study Type: Interventional

Study Design: Basic Design - Single arm Randomization - Non-randomized Blinding - Open -no one is blinded Control - Self control

Primary Sponsor: Institute - The University of Osaka

Condition: Condition - Myopia and myopic astigmatism Classification by malignancy - Others Genomic information - NO

Objective: Narrative objectives1 - To investigate the relationship between Quality of Vision (QOV) and myopia control efficacy by evaluating choroidal thickness and accommodation under different visual conditions. Basic objectives2 - Others

Intervention: Interventions/Control_1 - Study Day 1: Participants will view an unprocessed, clear video image. Study Day 2 (on a different day from Day 1): Participants will view a video image processed with a blur equivalent to +1.00 diopter defocus.

Eligibility: Age-lower limit - 7 years-old

Gender - Male and Female Key inclusion criteria - Individuals who have provided written informed consent to participate in the study. Key exclusion criteria - - having any ocular diseases requiring treatment other than for refractive errors (e.g., dry eye disease, allergic eye diseases). - having the history of any ocular surgeries that may affect visual acuity (e.g., corneal transplantation, corneal refractive surgery, retinal detachment surgery). - having corneal diseases associated with irregular astigmatism that may affect visual acuity (e.g., keratoconus). - having the history of any myopia control treatment within the past 12 months (e.g., orthokeratology, atropine eye drops, multifocal spectacles, multifocal contact lenses, dietary supplements). - having a best-corrected visual acuity of less than 0.8 (decimal). - cylindrical power of subjective refraction is greater than -1.50 D. - spherical power of subjective refraction is outside the range of +2.00 D to -6.00 D. - anisometropia greater than 1.50 D. - having the history of participating another clinical study that may affect visual acuity within the past 30 days. Target Size - 30
