Solotica Hidrocor Quartzo lenses create a dramatic transformation, turning deep brown eyes into a bright blue-green shade with subtle grey undertones. With no limbal ring, these lenses blend seamlessly for a soft yet striking, natural effect. The inner pupil ring has a slight yellow tint, adding a multi-dimensional look that changes in different lighting.
If you love the bright, icy effect of Quartzo but want a slightly darker, more natural alternative, check out Otaku Lover Cloud. Lover Cloud offers a deeper green-blue shade with the same high-opacity coverage, giving you a more wearable, toned-down version of this iconic color.
Made from breathable, moisture-retaining material, these lenses provide all-day comfort. Designed for up to 1 year of use, they are lightweight, easy to wear, and come with a contact lens case for safe storage.

Frequently Asked Questions
Is Solotica Hidrocor Quartzo good for dark brown eyes?
Yes. Hidrocor Quartzo has strong coverage and fully changes dark eyes into a light blue-green shade. The color shows up clearly without your natural eye color peeking through.
What's the difference between Solotica Hidrocor Quartzo and Natural Colors Quartzo?
Hidrocor Quartzo has no limbal ring (no dark outer edge), so it looks softer and more natural. Natural Colors Quartzo has a slight limbal ring, which gives the eye more definition and a sharper, more styled look. Both are the same shade, but the finish is different. If you're wanting something a little more subtle you can opt in for Otaku Lover Cloud.
How long do Solotica Hidrocor lenses last?
They are yearly lenses, made to last up to 12 months with proper care. They come in glass vials, sealed for safety and freshness, and are made in Brazil.
Is there a more subtle or natural-looking version of Hidrocor Quartzo?
Yes. If Hidrocor Quartzo feels too bold or bright, you might like:
- Otaku Lover Cloud - Still blue-green, but softer and less icy. More blended for everyday wear.
-
Otaku Inspire Emerald - More green with a soft blue tint. Great if you want a natural green-blue look instead of full aqua.
Are these lenses comfortable for long wear?
Solotica lenses are durable and thick, which some people like. But if you prefer a lighter lens that's easier to wear all day, many find Otaku lenses more breathable and comfortable.

All our Otaku lenses are made with a patented Plusierus Technology, our advanced "sandwich" design. This method seals the color inside the lens, between two clear layers, so the pigment never touches your eyes. Only the smooth outer surface touches your cornea. This protects your eyes, reduces irritation, and keeps them feeling fresh during long wear.

We also use an advanced 3-curve edge design, which creates a thinner, softer, smoother edge around the lens. In simple terms, it feels lighter on your eyes and helps reduce rubbing and dryness.

Otaku lenses are CE certified, ISO13485 compliant, and protected by Invention Patent.
