Smart glasses for air purification

With the escalation of global air quality concerns, the intersection of wellness and wearable design has emerged as a critical innovation space. The second wearable air purifier by Klara, creates a clean breathing zone through negative ion emission, in the format of glasses. This version has a bigger lens, to create a deeper zone of purification near your nose.

Bold is currently in the final stages of scientific validation with university partners, ensuring certified performance upon release on market.

Form — Driven by fluid dynamics. By increasing the lens offset and surface area, we engineered a larger stagnation zone for clean air accumulation. The transition from the thick, structural temples to the floating lens gives the object an avant-garde look.

UX — The design balances the rigorous ergonomic standards of premium eyewear with the volumetric constraints of the ionization stack. Activation is intuitive and discreet: a tactile button located on the underside of the temple allows for immediate power control without disrupting the frame's lines.

Process — Managed the complete design-to-validation pipeline. Delivered fully functional pre-production units and conducted targeted usability studies with key users to ensure market readiness.
