The process of eye washer categorization is continuous. After细分 (细分 needs clarification or replacement with a suitable term), the growth of eye washer categories to a certain scale will lead to further differentiation. For instance, the direction of differentiation for eye washers, or the eye washers searched for online could represent potential areas of differentiation. Each differentiation presents an excellent opportunity to create new types of eye washers. New eye washer brands can leverage the competition among traditional eye washer brands to sequentially enter consumer awareness.
(Note: The word "细分" in the original text requires more context for accurate translation, but it seems to refer to segmentation or classification. If so, it should be replaced with a more fitting term like "segmentation" or "classification".)
