The primary objective of this study is to evaluate the visual acuity, wearability, and quality of vision with two novel multifocal glasses designs in habitual myopia control glasses wearers, in a non-dispensing study after short-term wear.

Inclusion Criteria:

1. 8 - 15 years of age, inclusive.
2. Ability of the child to assent, and for one parent to provide permission to participate.
3. Had an eye examination within the past year.
4. Distance visual acuity of 20/25 (logMAR +0.10) or better in each eye with best corrected with sph/cyl subjective refraction.
5. Habitual glasses wearer of either MiYOSMART or Stellest for at least 2 months. (Can also be a contact lens wearer but needs to wear either MiYOSMART or Stellest spectacles for a minimum of 6 hours on a typical day.)
6. No history of binocular function anomaly (e.g., no history of strabismus), and no apparent strabismus.
7. Good general health (defined by medication use that has not changed within the last month and the absence of medical conditions or treatments that are deemed confounding to the data, as determined by the investigator).

Exclusion Criteria:

1. Current report of active ocular inflammation or infection.
2. Astigmatism > 1.00 D in either eye
3. History of previous eye surgery
