Study population: We enroll the clinical patients who was diagnosed with anisometropia (meaning that myopia exceeds 100 degree diopters during the refraction examination, and the difference between the other eye is more than 100 degree diopters). Age limit was 8 to 23 years old. The purpose and process were carefully addressed to the subjects and their guardians who signed an informed consent form before commencing this study.
Who may be able to join
- 8-23 years old children diagnosed with anisometropia and are willing to accept MiSight® 1 Day contact lens wearing treatment.
- No congenital eye diseases or eye diseases such as strabismus and amblyopia.
- Those who have been stated to be willing to participate in the program for at least 24 months and accept various evaluations.
Who cannot join
- Ocular surface disease( dry eye, keratoconus..)

What is being measured
The primary outcome is the main question the study is designed to answer.
Changes of the visual acuity in myopic children with different Misight 1 Day Contact Lens
The investigators measure the visual acuity of myopic children with different Misight 1 Day Contact Lens.
Measured: From the date of starting treatment, the visual acuity was measured 1 week, 1month and every 3 months up to 24 months.
Secondary outcomes (1)
Changes of axial length in myopic children with different Misight 1 Day Contact Lens
The investigators measure the axial length(mm) of eyeball of myopic children with different diopter of Misight 1 Day Contact Lens.
Measured: From the date of starting treatment, the axial length was measured, then repeat measure were performed every 6 months up to 24 months
