Yuga Labs Confirms UVA-A Emitting Lights Cause of ApeFest Eye Issues
Numerous participants exhibited signs of photokeratitis, an ailment resulting from ultraviolet (UV) light exposure, after last weekend's event.

Yuga Labs confirmed that UV-A emitting lights installed in one corner of the event was "likely the cause" of a series of eye-related medical emergencies that took place at the company's Ape Fest event in Hong Kong over the weekend.
Attendees of ApeFest reported blurred vision and burning eyes after attending the event last weekend. One attendee claimed they had eye issues for more than 30 hours following the event.
in an X post on Thursday, the company said it initiated a detailed investigation after reports came out, which comprised of an exhaustive examination of inventory records, material logs, and specification sheets, surrounding the instillation of its exhibits at ApeFest.
"This comprehensive investigation, undertaken in collaboration with Jack Morton Worldwide, the global brand experience agency that produced ApeFest 2023, has determined that UV-A emitting lights installed in one corner of the event was likely the cause of the reported issues related to attendees’ eyes and skin," the post read.

Prices of the popular Bored Apes Yacht Club slumped from 30 ether (ETH) to 28 ETH following the event and have since reversed declines.

The hardware hurdle: Cysic and Cardano clash over the future of decentralized compute

At Consensus Hong Kong 2026, Leo Fan questioned Midnight’s use of Google Cloud and Azure, as Charles Hoskinson justifies hyperscaler partnerships.
What to know:
- At Consensus Hong Kong 2026, Cysic founder Leo Fan warned that blockchain projects relying heavily on hyperscalers like Google Cloud and Microsoft Azure risk recreating single points of failure that undermine crypto’s decentralization ethos.
- Cardano founder Charles Hoskinson defended partnerships with major cloud providers for the Midnight privacy-focused network, arguing that global, privacy-preserving systems require hyperscaler-level compute while cryptography and confidential computing protect underlying data.
- The debate between Hoskinson and Fan centers on how to define decentralization, with Hoskinson prioritizing cryptographic neutrality over hardware ownership and Fan urging a hybrid model that limits reliance on Big Tech and extends decentralization to the compute layer itself.
