Abstract: Disclosed is a self-cleaning trial lens storage case comprising a rigid case body with a plurality of cylindrical lens receiving slots arranged in a dioptric sequence. Each slot comprises a microfiber wiping interface fixed along an inner wall and radially compressed against a trial lens during insertion and removal to wipe an optical surface of the trial lens. A magnet-receiving recess is formed beneath a base of each slot, and a permanent magnet is sealed within the recess below the received trial lens. A ferromagnetic rim interface on the trial lens aligns with the permanent magnet when the trial lens reaches the base. The microfiber wiping interface and the permanent magnet are integrated within the same slot so that the slot simultaneously performs passive wiping, magnetic centering, and positional retention during storage.
