When did it happen?
The breach date in the public record is August 1, 2026. The record was added to the catalogue on August 9, 2026 and last updated there on August 9, 2026.
What information was reported as exposed?
- Email addresses
- Names
- Phone numbers
- Physical addresses
These are incident-level categories. The record does not prove that every category was exposed for every affected person.
Who may be affected?
This record may be relevant to people who had an account or other relationship with Alcon or used alcon.com around August 1, 2026. A catalogue entry does not establish that every customer was affected or that every listed data category applied to each person. Compare the record with an official notice addressed to you.
What should you do?
Compare the organization, dates, and information categories with any notice you received. Use contact details you independently confirm.
Review your credit reports and consider a free credit freeze if identity information could support new-account fraud.
Treat unexpected breach follow-ups with caution. Do not use links or phone numbers in a suspicious message; contact the organization directly.
Choose actions that match the information involved. If you find signs that someone is using your identity, the Federal Trade Commission provides a personal recovery plan at IdentityTheft.gov.
