Embodiments describe an approach for smart lens-based transactions using eye contact. Embodiments comprise identifying a focus angle of a user wearing a smart lens, determining a smart lens-based transaction is occurring based on the focus angle including a second user or a point of sale sensor for a predetermined amount of time, and verifying the focus angle overlaps with a transacting focus angle of the second user or the point of sale sensor. Additionally, embodiments comprise authenticating the user based on biometric security measures on the smart lens, displaying an augmented reality prompt to the user on the smart lens, wherein the augmented reality prompt on the smart lens prompts the user to select a stored payment method and confirm an amount or file associated with the smart lens-based computing event, and executing the smart lens-based transaction based on the verified overlapping focus angles and the user confirmation.
