Who makes Kirkland Signature Daily Disposable Contact Lenses (90-pack)?
As of July 11, 2026, the manufacturer of Kirkland Signature Daily Disposable Contact Lenses (90-pack) is CooperVision, per on-label, first-party, or executive statement evidence.
The common claim
What most answers say — and what the evidence supports
Top answers say Kirkland Signature daily disposables are rebranded CooperVision MyDay lenses — and the evidence supports it. Costco's own optical store page lists "Manufacturer: CooperVision" for the Kirkland lens and shows the same stenfilcon A material and 54% water content as MyDay, and major contact-lens retailers cross-list the two as the same lens ("Same as MyDay Daily Disposable").
Evidence & sources
Every source is graded on the six-tier rubric and archived, so the citation holds even if the original moves or paywalls. The tier badge grades the source; the status grades our confidence in the maker.
Tier 4
Costco's own contact-lens store page lists, in the product details for the Kirkland Signature Daily Disposable 90-pack: "Material: stenfilcon A ... Water Content: 54% ... Manufacturer: CooperVision" — Costco naming the manufacturer outright, with the same stenfilcon A material and 54% water content as CooperVision's MyDay daily disposables. (Snapshot of March 2026; costco.com properties block bots, so this is cited via an existing Wayback capture.)
Tier 4
Re-verification, July 2026: the live vendor-filtered listing shows the Kirkland Signature Daily Disposable 90-pack as the single 'Kirkland Signature' brand result under the CooperVision, Inc. vendor filter — the attribution still stands on Costco's own store. Fresh content-verified snapshot taken 2026-07-11.
Tier 6
Retailer catalog corroboration: Lens.com files the product under "Contact Lenses > CooperVision > Store Brands > Kirkland Signature Premium Daily Disposable (Same as MyDay Daily Disposable)". Other major lens retailers (1-800 Contacts, ContactsAmerica, JustLenses) cross-list the same equivalence. Graded tier 6 because retailer catalogs are not independent reporting; included as corroboration alongside the tier-4 Costco anchor.
