・Instructions on handling lenses
1. Keep your fingernails short and smooth to avoid scratching your eye or your lenses.
2. Always wash your hands with soap and rinse carefully before handling your lenses. Lenses may become
contaminated if you do not wash your hands properly.
3. Always handle your lenses somewhere that is well-lit, clean and sterile.
4. Your contact lenses may become damaged depending on how you handle them.
・Checking the lenses and blister packaging
1. Check which lenses are for the right eye and which lenses are for the left eye.
2. Check if there is anything wrong with the lenses and blister packaging before opening. If there is anything
wrong, for example, if there is any damage or leakage, do not open and contact the point of purchase.
・Removing the lenses from the blister packaging
1. Break off the blister packaging by folding down the sides.
2. Remove the label, keeping a firm hold on the blister packaging and the label. When doing this, be careful not
to cut your hand on the blister packaging or label. Also note that the lens storage solution inside the blister
packaging may splash upon removal of the label.
3. Remove the lens from the blister packaging by sticking the lens to the pad of your index finger. Alternatively,
turn the blister packaging upside down and empty the lens together with the storage solution into the palm
of your hand. Take care, because if you dig your nail into the lens or scrape the lens on the rim of the blister
packaging on removal, the lens may be damaged.
・Checking the lenses
1. Hold the edges of the lens from the side and gently move up and down to remove the liquid.
2. Put the concave surface on the index finger of your dominant hand and check which the right and wrong sides
of the lens are. A lens has a right side and a wrong side.
Ensure that the lens is not inside out. Place the lens on your right index finger and verify the shape. (fig. 1
and 2)

3. Check if there is anything wrong with the lens, for example, deformation, discolouration, foreign matter,
damage, scratches and dirt, and do not wear the lens if there is anything wrong with it.
・Inserting lenses
1. Put the lens onto your finger, and, with the middle finger of the same hand, pull down your lower eyelid. With
the index finger of your other hand, pull up your top eyelid. If you put your finger on your eyelash line, you
can open your eyes wide.
2. Look in the mirror so that your cornea comes into the center of your eye. Slowly bring the lens close to your
eye and put it gently in place, still looking in the mirror. If you glance upwards when doing this, the lens will
not be properly centered on your cornea.
3. When you have placed the lens properly on the cornea, slowly remove your index finger and then remove your
fingers which had been holding your eyelids, starting with the bottom lid first and then the top lid. If you
remove your fingers quickly and blink your eye shut, the lens may change position or fall out.
4. Check in the mirror that the lens is on top of your cornea and, covering the opposite eye with your hand, check
your sight in your right and left eyes.
5. Follow the same procedure to fit the lens in your other eye.
・Removing the lenses
1. Check the position of the lens in the mirror.
2. Looking straight in the mirror, hold the mirror upward and look at the eye reflected in the mirror.
3. With your middle finger, slowly pull your lower lid down, and with the index finger of the same hand, move
the lens down from the cornea.
4. In this position, use the pads of your thumb and index finger to gently take hold of the bottom of the lens.
To avoid scratching your eye, take care not to touch your eye directly with the tips of your fingers or your
fingernails.
If you are unable to remove the lens, blink several times and then try again.
・Lens care
1. Since protein and lipids present in your tears will become attached to the surface of your contact lenses as
you wear them, it is important to follow the lens care regimen for washing, rinsing, disinfecting and storing
your lenses. Failure to follow the lens care regimen will result in lenses becoming dirty and may result in
serious eye disorders or eye infections.
2. Use lens care products suitable for soft contact lenses. You can use a chemical disinfection system.
3. Use lens care products according to their Instructions for Use.
4. The extent to which lenses become dirty varies from person to person. If your lenses tend to become dirty,
try rubbing your lenses with a cleaning solution or using a protein removal liquid. If the dirt will not come
off, even if you have not worn the lens for a full two weeks, replace it with a new one.
5. When following the lens care regimen, use a plug or contact lens sink mat to prevent the lenses from being
washed away.
6. Empty and clean contact lens cases with digital rubbing using fresh, sterile disinfecting solutions/contact
lens cleaner (never use water), followed by rinsing with fresh, sterile disinfecting solutions (never use water)
and wiping the lens cases with fresh, clean tissue is recommended.
7. Replace your lens case roughly every one or two months. Prolonged use will result in a proliferation of
bacteria due to the build-up of dirt, rendering disinfection inadequate and leading to eye disorders or
infections.
8. Do not change the contact lens care system without consulting an eye care professional.
