Abstract: A device including an eye cup portion affixed to one end of an extendible tube portion, the other end of the tube portion is adapted for releasably attaching the tube portion to the nozzle of a spray-mist fluid dispenser. In combination, the device and mist dispenser are operable for controlling the delivery of a fluid to the eye. The device functions both as mask to confine the distribution of the spray mist ejected from the nozzle upon the eye and as a jig operable for adjusting the distance between the mist dispenser nozzle and the eye cup portion of the device. In operation, with the device affixed to a spray mist dispenser nozzle and the tube portion unextended (nozzle closest to the eye), a dense mist is delivered to the cornea and surrounding eye tissues when mist is dispensed. When the tube portion is extended, the spray mist dispenser nozzle is further from the eye cup thereby reducing the density of the spray mist impinging on the eye.
