Nictavi makes ophthalmic medical devices and we carry a single one: a disposable device for nighttime eyelid closure, 15 to a pack. It is a narrow product with a specific audience, which is unusual on a shelf full of drops and masks.
Each device is used once and discarded, so a pack covers 15 nights. It sits on the skin around the lid rather than on the eye itself. Because the design is single use, there is nothing to clean, store or replace on a schedule.
Lid closure during sleep is something eye care professionals ask about, and some people find their lids do not fully meet overnight. If a clinician has raised that with you, this is the category they were pointing at. If nobody has, this is not the product to start with on your own: an eye exam is the right first step, since what looks like a nighttime issue can have several different explanations.
Nictavi sits near two other groups we carry. Sleep and moisture masks cover the eye area with fabric and are reusable. Heat masks are a daytime or evening routine item and serve a completely different purpose. The Nictavi device is narrower than either and is not a substitute for them, or for anything your eye doctor has already recommended.
Adhesives sit against skin, so anyone with sensitive skin, recent eye surgery, or an active lid condition should raise it with their eye care professional before adding a device like this to their night routine.
