Best corrected visual acuity (BCVA): 20/20 or greater.<br><br> 4. Data from patients who have utilized or are utilizing red light therapy as part of<br> their myopia management strategy.<br><br>Exclusion Criteria:<br><br> 1. Ophthalmic diseases other than refractive errors, including but not limited to<br> strabismus and binocular vision abnormalities in either eye.<br><br> 2.
