From February 20 to 22, 2025, a significant event in the eyewear industry took place: The SIOF was held in Shanghai, China, and featured participation from over 900 companies. Thondar unveiled its latest defocusing customized myopia control glasses. This release marked a significant expansion of its channels in optic shops.

Thondar Defocus customized glasses stand out from similar products as they are uniquely tailored to individual needs and are classified as non-standard items. A recent clinical study demonstrated that they provide the best myopia control effects over one year. Additionally, the company maintains strict control over pricing and sales channels, which has captured significant attention at exhibitions.
