Learn how to achieve a full coverage look with 17mm Tokyo N Green sclera lenses, including application steps, care tips, and design insights.

Quick Answer

For a full coverage look, the 17mm Tokyo N Green sclera lens covers the entire visible eye area, so you need to apply it with care and follow a proper insertion routine to avoid air bubbles and discomfort.

What Makes 17mm Sclera Lenses Different

Unlike standard contact lenses that sit on the cornea, sclera lenses are larger and rest on the white part of the eye (the sclera). A 17mm diameter covers nearly the entire visible eye, creating a dramatic, full coverage effect essential for cosplay and special effects.

The 17mm Tokyo N Green lens features a green design that covers the whole eye, giving an alien or anime-inspired look. Because of its size, it requires more careful handling than smaller lenses, and you need to allow extra time for insertion and removal.

Important Trade-Offs to Consider

The large diameter provides full coverage but also means the lens covers more of the eye surface, which can reduce oxygen flow. The Tokyo N Green has a water content of 40% and is made of hydrogel, so it's suitable for short wear periods, not for overnight use.

Also, because the lens is larger, it may feel more noticeable at first. You should start with short wearing times and gradually increase them to let your eyes adjust. If you experience persistent discomfort, remove the lens immediately and consult an eye care professional.

Step-by-Step Application Guide

Step 1: Prepare Your Workspace: Wash your hands thoroughly with soap and water, then dry them with a lint-free towel. Clean your workspace and have a mirror, lens case, and fresh solution ready. Never use tap water on the lenses. Check that your solution is fresh and not expired before starting.
Step 2: Inspect the Lens: Remove the lens from its blister pack and inspect it for any tears or debris. Place it on your fingertip and check that it forms a nice bowl shape, not folded or flipped inside out. If the edges flare out, it's inside out. If the lens looks damaged, do not wear it; use a new pair.
Step 3: Position the Lens: Hold the lens on the tip of your index finger, making sure it's well-balanced. Use your other hand to hold your upper eyelid open and your middle finger to pull down your lower eyelid. Look straight ahead or slightly up. Keep your eyes wide open to avoid blinking during insertion.
Step 4: Insert the Lens: Gently place the lens onto your eye. Since it's a sclera lens, it will cover more of the eye surface. Press lightly and hold for a second to let it adhere. Blink slowly to help it settle. If you feel a bubble or the lens shifts, remove and reinsert it.
Step 5: Check Alignment: Look in the mirror to ensure the lens is centered and the design is positioned as desired. The green pattern should cover your iris completely. If it's off-center, gently move it with a clean fingertip. If the lens is uncomfortable or blurry, remove and reinsert it.
Step 6: Remove and Clean: After wearing, wash your hands again. Use your fingertips to slide the lens downward onto the white of your eye, then pinch it gently to remove. Clean the lens with fresh solution and store it in its case with fresh solution. Never reuse old solution; always use fresh solution for storage.
