Is it the same level as Mohsen?

It's different. Kuna and Mosen are both glasses brands under Xiamen Ruiya Optical Co., Ltd., both of which belong to the same company, with similar manufacturing processes but different positioning. Mosen's grade belongs to the middle range, and most products are priced between 500 and 800 yuan, while Mona's grade belongs to the public, and the price is more affordable.
