At 0.99, Pearle Vision is the overwhelming anchor of Optometry's similarity graph — a gap of more than 0.10 separates it from every other neighbor in the top 10. That concentration defines the spike shape here: one neighbor pulls far ahead, and the rest form a secondary cluster.
Beyond Pearle Vision, the top 10 contains no other Optometry subcategory entries. What fills positions two through ten is a cross-kind mix: DSW (Designer Shoe Warehouse) at 0.88 (Footwear), The Men's Wearhouse at 0.86 (Mens Apparel), Pet Care & Services at 0.85 and Dogtopia at 0.85 (both Pet Care and Services), Music at 0.85 (Music retail), LOFT at 0.85 (Womens Apparel), Barnes and Noble at 0.85 (Bookstores), Panera Bread at 0.84 (Casual Dining), and Portillo's Restaurants at 0.83 (Casual Dining). Tallying the subcategories: Apparel accounts for three slots, Restaurants two, Pet Care two, and single entries for Music, Bookstores, and Footwear. No single non-optometry subcategory dominates — the secondary cluster is genuinely mixed across retail, dining, and services.
The overall picture is an audience shaped primarily by one structural twin in Pearle Vision, surrounded by a broad assortment of brick-and-mortar service and retail categories — suggesting the Optometry audience is defined less by a single lifestyle cluster than by a general pattern of in-person, franchise-adjacent consumer behavior.
