Advanced Color Drops

Still Wearing Colored Contacts for Hours?

Colored contacts can feel dry, uncomfortable, and high-maintenance after hours of wear. Timilk® IrisShift offers a contact-free way to change your eye-color appearance — with visible color development in about 2 hours and temporary results lasting up to 5–7 days. No daily lens insertion, removal, or visible lens edges — just a natural-looking iris tone that fits easily into your routine.

Skip the Lenses. Keep the Color.
Both can change the way your eyes look — but the daily routine is completely different. IrisShift gives you a simple, contact-free option for exploring a new eye-color appearance without wearing, cleaning, and replacing colored lenses every day.

At the heart of IrisShift is NAG Iris Color Technology, developed to support a gradual change in visible iris-color appearance rather than covering the eye with an artificial colored lens. The result is designed to blend with your natural iris pattern for a softer, more natural-looking temporary color effect.

Visible Eye Color Development in About 2 Hours

Timilk® IrisShift is designed to create a visible shift in eye-color appearance in about 2 hours, with temporary results lasting up to 5–7 days. Powered by NAG Iris Color Technology, the formula is designed to work with the appearance of your natural iris rather than covering it with a colored lens.
The result is a softer, more natural-looking color effect that blends with your existing iris pattern — without the daily routine of inserting and removing colored contacts.

Designed for a Softer, More Natural-Looking Color Effect
Unlike colored lenses that sit on top of the eye, IrisShift is designed to support a gradual visible change in iris-color appearance. The result is a softer, more blended look without visible lens edges.

Real Stories From Customers Who Changed Their Look With IrisShift

“I’ve always wanted lighter blue-grey eyes, but I hated wearing colored contacts all day. With IrisShift, the change looked much softer and more natural than I expected. I could still see the detail in my own iris — just with a completely different tone.” — Mia R. ⭐⭐⭐⭐⭐

“My natural eyes are very dark brown, so I honestly wasn’t sure if I would notice much of a difference. The hazel-green tone came through gradually and looked surprisingly blended — not like I had a colored lens sitting over my eye.” — Sophie L. ⭐⭐⭐⭐⭐

“I’ve always loved violet eyes but never liked how purple contacts looked on me. IrisShift gave my eyes a cooler violet tone while still keeping the natural pattern underneath. It feels much more like my eyes — just different.” — Olivia M. ⭐⭐⭐⭐⭐
