I’d be surprised if you damaged your eyes with any LEDs in the visible spectrum. Walking around in midday sun exposes you to orders of magnitude more energy. Maybe if you had focusing lenses on them, and they were really high power, like the kind that needs heat sinks to operate safely. If you had say UV LEDs, all bets are off since it wouldn’t trigger the pupillary light reflex to close down the iris.

Some white LEDs are actually near-UV LEDs coated with a phosphor layer to emit visible wavelengths. Could be GP got LEDs with poor coating allowing UV through?

  The visible component would still cause your eye to narrow the pupil.
