Some attendees of the Bored Ape Yacht Club's (BAYC) ApeFest event in Hong Kong have reported experiencing eye problems, including temporary blindness and blurred vision. The problems are believed to have been caused by flashing lights that were used during the event. The BAYC has apologized for the incident and said that it is investigating the matter. The company has also said that it will take steps to prevent similar incidents from happening in the future. The incident has raised concerns about the potential health risks of flashing lights at events. Some experts have said that flashing lights can trigger seizures in people with epilepsy, and that they can also cause eye damage in people who are not epileptic.
