Assessment of DOT Spectacles in Chinese Children

Clinical Assessment of DOT Spectacle Lenses in Chinese Children

This is a randomized, controlled, evaluator-blinded, multicenter, two-arm parallel group clinical trial to evaluate the continued safety and efficacy of Diffusion Optics Technology (DOT) spectacle lenses by comparing to single vision, impact-resistant spectacle lenses in reducing the progression of myopia in children of Chinese origin.

Inclusion Criteria:

1. Children 6-13 years of age
2. SER error between -0.75D and -5.00D
3. Willingness to wear study spectacles and participate in the trial for 12 months without contact lens wear

Exclusion Criteria:

1. Prior usage of atropine, multifocal contact lenses, or orthokeratology (ortho-K)
2. Astigmatism worse than -1.50 DC (by manifest refraction) in either eye
3. Anisometropia (SER manifest refraction) greater than 1.00 D
