<Precautions for use>
1. Inserting/removing the lenses
(1) Lens handling precautions
•Keep your fingernails short and smooth.
•Wash your hands with soap before handling lenses.
•Do not dig your nail into the lenses or touch your eyes directly while inserting/removing the
lenses.
(2) Removing the lenses from the packaging
•Pull up the plastic cap to peel off the aluminum cap.
•Be careful to avoid cutting your hands or fingers on the aluminum cap while opening the
container.
•Remove the rubber stopper and turn the vial upside down to empty the lens together with
the storage solution into your palm.
•Check to determine the inside and outside of the lenses. The lenses should be free of any
deformation. If you use the lenses in both eyes, also confirm which lens is for the left eye
and which lens is for the right eye.
(3) Inserting the lens
1) Place the lens onto your index finger. Then, pull down on your lower eyelid with the
middle finger of the same hand, and pull up on the upper eyelid with the index finger of
the opposite hand. Placing your fingers on your eyelash line helps you open your eye
wider.
2) Look in the mirror so that the cornea comes into the center of the eye. Slowly bring the
lens close to your eye and put it gently in place while looking in the mirror. If you glance
upward in this time, you cannot center the lens on the cornea correctly.
3) When you have placed the lens properly on the cornea, slowly release your index finger
and then release the fingers holding the eyelids in the order of the lower eyelid and upper
eyelid. If you release the fingers quickly or blink, the lens may move or fall out.
4) Confirm that the lens is in front of the cornea. Check in the mirror, or cover the opposite
eye with your hand to check your sight in your right and left eyes.
5) If you use the lenses in both eyes, follow the same procedure to fit the lens in the other
eye.
(4) Removing the lens

Inside out

1) Check the position of the lens in the mirror.
2) Facing front, raise the mirror and look at your eye in the mirror.
3) Gently pull down on the lower lid with the middle finger and slide the lens down with the
index finger of the same hand.
4) In this position, gently take hold of the bottom of the lens to remove the lens with the
pads of the thumb and index finger.
