To develop a sensorial identity for Bausch + Lomb’s Biotrue, a guerrilla advertising project could leverage unexpected, visually-driven tactics in urban environments. Imagine street art murals depicting hyper-realistic eyes that seem to follow passersby, interactive projections that respond to movement and create surprising optical illusions, or pop-up installations in unexpected locations that offer miniature "eye spas" with soothing visuals and sounds. These tactics would aim to disrupt routine and capture attention, reinforcing the message that "the eye is stronger" – moving beyond analytical data and tapping into emotional connection. This approach creates a memorable, tangible experience, associating Biotrue with impactful sensory encounters and building a brand identity rooted in feeling, rather than just figures on a chart.
