Instructions for use

1. Wash your hands.

2. Open the bottle. Do not touch the tip after opening the bottle.

3. Lean your head back (Fig. 1).

4. Pull down your lower eyelid with your finger and hold the bottle in your other hand. Squeeze the bottle so that one drop falls into the eye (Fig. 2).

5. Close your eyes and press the tip of one finger against the corner of the eye for around 1-2 minutes. This will prevent the drop running through the tear duct into your throat and most of the drop will remain in the eye (Fig. 3). If necessary repeat steps 3 to 5 with your other eye.
