Z Clear Lens Cleaner Properties

Z Clear is one formula in three formats. This page sets out what the formula actually does, what is deliberately left out of it, and what you can reasonably expect from a single application.

What the formula does

• Anti-fog — Z Clear does not repel moisture. It spreads condensation into a film so thin and even that light passes straight through it, so instead of a white haze you get a lens you can still see through. This is why it keeps working in a humid kitchen or a cold-to-warm doorway, where a water-repellent coating simply beads.
• Oleophobic — reduces the fingerprints, skin oil and smudges that build up from ordinary handling, and makes the next clean easier.
• Anti-static — leaves the surface less inclined to attract dust and lint, which is most of what settles on a lens between cleans.
• Fills fine surface scratches — the wax-like base of the Paste settles into shallow scratches so light passes cleanly rather than scattering at the edges. It fills, it does not repair: a deep gouge needs a new lens, and the effect is renewed each time you reapply.

What is not in it

Most of what makes Z Clear safe is what it leaves out. The formula is free of:

• Alcohol — the usual active ingredient in cheap lens sprays. It cleans well and quietly strips anti-reflective and factory anti-fog layers over months of use.
• Ammonia — the active ingredient in blue household glass cleaners. It crazes acrylic and polycarbonate, leaving a permanent web of fine cracks.
• Abrasives — nothing in the formula cuts or polishes the lens surface.
• Silicone

It is pH-neutral and hypoallergenic, which is why it is used in clinical and cleanroom settings as well as on eyewear.

Coatings it is safe on

Z Clear is safe on every lens coating we have tested, including anti-reflective treatments such as Crizal, ZEISS DuraVision and Hoya HiVision, plus polarized, mirrored, photochromic and blue-light filtering lenses. It is also safe on acrylic and polycarbonate — aircraft canopies, motorcycle windshields, face shields and safety goggles. See the AR-coating safety guide for detail.

How long one application lasts

Up to 72 hours per application. We recommend re-treating daily.

The 72 hours is what a single application can hold, not how often you should apply it. Humidity, temperature swings, exertion and how often you handle the lens all shorten it. A fresh pass each morning is the habit most daily wearers land on, and repeated use builds the film up rather than wearing it down.

All three formats share the same active formula, so all three hold for the same length of time. What differs is the carrier: the Paste lays down a thicker, more durable film and travels without leaking, while the sprays cover large surfaces faster.

How to apply it

Z Clear goes on the lens, not on the cloth. Your fingertip spreads it. The cloth only comes out once it is dry.

1. Apply a small amount directly to the lens — a pea-sized pinch of Paste, or one or two sprays.
2. Spread it across the surface with a clean fingertip until it turns dry, usually five to ten seconds.
3. Once dry, buff it clear with a microfiber cloth.

Buffing while the product is still wet lifts it straight back off the lens. That single mistake is the most common reason people conclude it did not work. Full walkthrough: How to Use Z Clear.
