I’m Irene, a Taiwanese pharmacist working in a Japanese drugstore. After checking maps, train times and photos all day, you may find yourself looking at the “PC” box on the eye-drop shelf. Before choosing it, check your lenses, not just the big letters. Digi Eye Contact is not suitable for every type of contact lens.
Match the full name, not just “PC”
The full product name is ロートデジアイコンタクト, a Japanese Class 3 OTC medicine. The barcode is 4987241165377. The large “PC” lettering is a useful shelf clue, but the word コンタクト is the important product check. Digi Eye a and other eye drops are different products; do not transfer these directions to them.
Rohto says Digi Eye Contact has had a package redesign without a change to its formulation. Old and new packaging may therefore look different. Match the full name and follow the directions supplied with the bottle you buy.
Can you use it with your lenses in?
Ordinary soft, hard, oxygen-permeable and disposable contact lenses: the official product information allows use while wearing them. It can also be used without lenses.
Colored contact lenses are excluded. Do not assume cosmetic or circle lenses are covered just because they are soft or disposable. If you cannot identify your lens type, show the lens package to the pharmacist first.
These drops are intended for eye fatigue, discomfort while wearing soft or hard contact lenses, itchy eyes and blurred vision such as that associated with excess discharge. The listed indications also include inflammation caused by ultraviolet or other light, and prevention of eye disease after swimming or when dust or sweat enters the eyes. They are not a contact-lens cleaning solution.
Screen use can be a reason you notice tired eyes, but it is not a diagnosis. Do not treat severe pain or persistent blurred vision as ordinary “screen fatigue.” This medicine is not a blue-light filter, and we are not claiming it prevents permanent screen-related eye damage.
Use the right amount, without touching the tip
5–6 times a day. Use only as an eye drop and follow the package directions. Do not increase the amount or frequency because your eyes still feel tired.
Keep the bottle tip away from the eye, eyelids and eyelashes. Contact can contaminate the contents. Do not use cloudy liquid. Children must use it under an adult’s supervision.
If you use prescription eye drops or another eye medicine, ask your doctor or pharmacist how to combine them. The Contact insert does not supply a universal interval for all other eye drops; an interval given for another product should not be copied here.
Close tightly and store in a cool place away from direct sunlight. Do not leave it in a car or near a heater at 40°C or above. Keep it away from children.
Do not share the bottle, transfer it to another container or put other substances into it. Do not use it after the printed expiry date. Even within that date, the Contact insert gives 2–3 months after opening as a guide, provided its storage instructions are followed. This does not make cloudy or contaminated drops safe to keep using.
When to ask first, stop, or get help
Ask before use if you are under a doctor’s care, have previously had an allergic reaction to medicines or other substances, have severe eye pain, or have been diagnosed with glaucoma.
Stop immediately and seek advice if you develop a skin rash, redness or itching, or eye redness, itching, swelling, or stinging pain. These may be adverse reactions. Take the box to a doctor, pharmacist or registered OTC medicine seller.
Stop and consult if blurred vision does not improve, or symptoms have not improved after 5–6 days. Do not wait for that time limit if a possible adverse reaction occurs.
What is in it?
The six active ingredients are zinc sulfate hydrate 0.1%, vitamin B6 0.1%, taurine 1%, neostigmine methylsulfate 0.001%, d-α-tocopherol acetate 0.01%, and sodium chondroitin sulfate 0.5%. The formula includes ingredients used for inflammation, focusing-muscle fatigue and corneal protection. More ingredients or a stronger cooling sensation do not prove it is the right medicine for your symptoms.
Additives include sesame oil and cooling ingredients such as menthol. If you have an ingredient allergy, check the complete list on the box with a pharmacist rather than relying only on the active-ingredient summary above.
A quick pharmacy check
「ロートデジアイコンタクトを考えています。このコンタクトレンズをつけたまま使えますか？」
“I’m considering Rohto Digi Eye Contact. Can I use it while wearing these lenses?”
Show your lens package and any other eye medicines. This is more useful than asking only for “the PC eye drops.”
