No conflict. They are two different brands. "Damingfu Glasses" is a brand name, referring to a series of glasses products developed by a certain glasses company; while "Daming Glasses" is another brand name, coming from the products of another glasses company. Since the registration and use of a brand or trademark requires legal intellectual property protection, there may be differences between the two brands, which need to be distinguished at the level of trademarks, brands and related laws.
