Patented Technology of Evolve®

Evolve® has been designed to combine the benefits of single-use preservative-free eyedrops with the convenience of a multi-dose bottle. At the heart of this innovation is its patented Pure-Flow Membrane Technology, designed to keep every drop safe and sterile.

The system features a one-way valve paired together with a silicone membrane that filters returning air. After each drop is dispensed, this mechanism prevents contaminated air or liquid from flowing back into the bottle, maintaining the sterility of the solution without the need for preservatives.

The result? Long-lasting sterility for up to 90 days after opening, something conventional multi-dose eye drops cannot achieve, even with preservatives. Evolve® delivers the safety of single-use vials with the practicality of everyday use.

Thoughtfully designed for patient ease and comfort, the bottle also features a blue tip for more precise instillation, while its low-squeeze design ensures a calibrated, consistent drop every time.
