DESCRIPTION

Kokushibo's red-and-gold Upper Rank One eyes, with a clear central opening. This open-pupil version leaves a small unprinted circle at the center of each lens. The circle interrupts the black character artwork; it is a visible part of this design, not a printing defect. The red outer ring, golden iris field and black markings give a graphic finish for Demon Slayer cosplay, Upper Moon group shoots and character close-ups.

Choose the pair composition first, then select one Power. Every option includes one pair (two lenses), both in the same selected power. The full character pair has an Upper Rank design for the left eye and a One design for the right eye. Same-design pairs are also available for costume styling. The examples show how the artwork sits on the eye; the appearance varies with natural iris color, fit and lighting, including on dark brown eyes.

Pair option Two lenses included
Mismatched Pair 1 Upper Rank (left-eye design) + 1 One (right-eye design)
Left Eye Pair 2 identical Upper Rank designs
Right Eye Pair 2 identical One designs

Specifications: 6-month replacement · Lens diameter 14.5 mm · Base curve 8.5 mm · Water content 40%. Available in plano (0.00) and the prescription powers shown in the Power menu. Follow the replacement and care instructions supplied with the lenses. Wash and dry hands before handling, use fresh contact-lens solution, never share lenses, and never sleep in them.

FAQ

How is this different from the original full-print version?

This version has an unprinted central optical area. The original full-print version carries the artwork across the center and can limit vision. An open center does not guarantee unrestricted vision or confirm that the lens fits your eyes.

Can I buy two identical designs?

Yes. Left Eye Pair includes two Upper Rank designs. Right Eye Pair includes two One designs. Mismatched Pair includes one of each. Every option is sold as a pair, not as a single lens.

Do I select the power once or twice?

Select it once. Both lenses in your pair use that power. If you need different powers in your two eyes, contact Mojosee before purchasing; this menu does not create a mixed-power pair.

Is this a yearly lens?

No. This open-pupil product is the 6-month replacement version. It is separate from the existing full-print listing.

Do these lenses create all six eyes?

No. One pair is worn on your two natural eyes. Create the four additional eyes with skin-safe makeup or costume details outside the eye.

U.S. customers need a valid contact-lens prescription, including for plano decorative contacts. See the prescription verification process. Compare more Demon Slayer contact lenses.

WEAR & CARE

Wear & Care

How to put in, remove and clean colored contact lenses — step by step illustrated guide
Before anything

Wash and dry your hands first — every single time.

Putting lenses in
  1. 1Rinse the lens with fresh lens solution.
  2. 2Check it's not inside out — the edge should curve up like a bowl, not flare out.
  3. 3Hold your upper and lower eyelids open with your fingers.
  4. 4Place the lens gently on your eye, look around, and blink slowly.
Removing lenses
  1. 1Look up and pull down your lower eyelid.
  2. 2Gently pinch the bottom edge of the lens between your finger and thumb.
  3. 3Place the lens straight into its case — never leave it dry.
Cleaning & storage
  1. 1Put a few drops of solution on your palm and place the lens on it.
  2. 2Rub the lens gently back and forth with your fingertip.
  3. 3Rinse, then store it in a clean case filled with fresh solution.
  4. 4Replace the solution every day, and keep L / R caps the right way up.

Never share lenses, never sleep or shower in them, and stick to the stated replacement cycle. Discomfort or redness? Take them out and give your eyes a rest.

SHOPPING TIPS
  • Each order unit is 1 pair (2 lenses) of the same power. If your eyes need different powers: within 0.50, one pair at the weaker power is usually fine; if the gap is larger, add one pair per power to your cart.
  • Normal vision? Choose 0.00 (plano). In the U.S., plano colored contacts still require a valid prescription.
  • Double-check your shipping address, phone and email before checkout — international parcels cannot be redirected once dispatched.
  • Need to change or cancel? Use the support option in your order confirmation as soon as possible, before your order is dispatched.
  • Free standard shipping applies to U.S. orders over $49 and UK, Australia and Canada orders over $49. Below these thresholds, standard shipping is $10.99. Standard delivery takes 14–20 days door to door (7–15 days after your tracking number is issued) — ordering for an event? Count backwards from your date.
ASTIGMATISM & POWER
  • Can I wear these lenses if I have astigmatism?
  • No—these are spherical, non-toric lenses. They have no CYL or AXIS option and do not correct astigmatism. If your eye-care professional has approved a spherical-equivalent power, use the calculator only as an SPH-only reference and only choose a value shown in this product’s Power menu. Vision can remain softer than with a properly fitted toric lens.

  • How to work out your contact lens power
  • Step 1 — vertex distance. Glasses sit about 12 mm in front of the eye, contact lenses sit on it, so strong prescriptions need less power in a contact lens. Below −4.00 no change is needed. −4.00 to −5.75 reduce by 0.25; −6.00 to −7.75 reduce by 0.50; −8.00 to −9.75 reduce by 0.75; −10.00 to −11.75 reduce by 1.00.

    Step 2 — spherical-equivalent reference. Only if approved by your eye-care professional, add half of CYL to estimate an SPH-only reference. This does not reproduce CYL/AXIS correction or correct astigmatism.

    Step 3 — rounding. If that power is not stocked, choose the next weaker step, never the stronger one.

    Example: SPH −4.50 with CYL −1.00 → −4.25 after vertex → −4.25 + (−0.50) = −4.75.

  • Work out your power
  • Power calculator

    This is an SPH-only spherical-equivalent reference—not toric correction. Use it only if your eye-care professional has approved a spherical lens for you. It cannot reproduce CYL/AXIS or correct astigmatism, and it only returns a power actually stocked for this product.

    One pair = 2 lenses of the same SPH power. This calculator does not reproduce CYL/AXIS and does not correct astigmatism; vision may remain softer than with a properly fitted toric lens. It is not a prescription. In the U.S. every contact lens, including 0.00, needs a valid prescription and fitting from an eye-care professional. Full conversion chart & FAQ →

  • My two eyes need different powers — what do I order?
  • One order unit is 1 pair (2 lenses) of the same power, so there is no separate left/right selection.

    If the two eyes are close (about 0.50 apart or less), the simplest option is one pair at the weaker of the two powers. Slight under-correction is far more comfortable than over-correction.

    If the gap is larger, order two pairs — one at each power — and use one lens from each. The spare lens of each pair stays sealed as a backup.

  • Before you order
  • Only your eye care professional can confirm the right power, base curve and diameter for your eyes. In the U.S. every contact lens, including 0.00 (plano), requires a valid prescription and a fitting. Use this chart as a guide, not as a prescription.
