The science, made simple

Warm moisture.
Cool lenses.
That familiar mist.

Glasses fog when moisture in the air condenses on a cooler lens surface. Tiny water droplets scatter light, creating the cloudy layer that interrupts your view.

Some anti-fog treatments help moisture spread into a more even, transparent film instead of collecting as visible droplets. How a solution works—and how you maintain it—depends on the product.

Anti-fog is designed to reduce fogging. Performance varies with conditions, lens compatibility and correct use.

Sound familiar?

Three moments when
fog likes to show up.

Tell us when your lenses tend to fog. It helps us guide you toward a suitable option for your daily routine.

Your coffee break.
Or your next recipe.

Steam from a hot drink or cooking can meet cooler lenses and create condensation. Give steam some space and ask about a compatible anti-fog solution.

When you’re
wearing a mask.

Warm exhaled air reaching your lenses can cause misting. A well-fitting mask can help limit upward airflow; anti-fog care may also help reduce condensation.

From the cold
into somewhere cosy.

Cold lenses can fog as you enter warmer, humid air. Letting your glasses adjust to the temperature can help as the condensation clears.

Make the right choice for your lenses

A little guidance.
A better lens routine.

Start with compatibility

Tell us your lens type, existing coatings and when fogging happens. We’ll help you check suitable options before you order.

Follow the specific instructions

Some systems need a special cloth or activator. Other treatments need reapplication. Use the care instructions supplied with your chosen product.

Keep the routine gentle

Use lens-safe cleaning products and the recommended cloth. Avoid household cleaners or improvised anti-fog remedies unless your lens manufacturer approves them.

Know your lens features

Fog, reflections or fingerprints?

They can all interrupt your view, but they need different solutions. One feature does not automatically include the others.

Feature What it targets What to know
Anti-fog Condensation that creates a misty lens surface Compatibility and ongoing care depend on the treatment.
Anti-reflective Reflections from the lens surface Also called anti-glare or AR coating. It is not automatically anti-fog.
Anti-smudge Oily marks and easier cleaning Helps with fingerprints; it does not guarantee fog-free lenses.

Before you choose: confirm current availability, compatibility and any additional cost for your selected lens package. Anti-fog is not assumed to be included with every replacement lens.

Why do my glasses fog up?

Moisture condenses when warm, humid air meets a cooler lens surface. Common examples include entering a warm building from the cold, wearing a mask, or being near steam.

Will anti-fog lenses never fog?

No solution should be treated as a guarantee in every environment. Results depend on the treatment, conditions, compatibility and following its care instructions.

Is anti-fog the same as anti-glare coating?

No. Anti-fog addresses condensation. Anti-glare, also called anti-reflective coating, reduces reflections from the lens surface. Check the features of your selected lens package.

Can I use anti-fog spray on my current glasses?

Only use a product confirmed as compatible with your lens material and coatings. Contact us with your lens details before using a new treatment, especially if you are unsure of the existing coatings.

How long does an anti-fog treatment last?

There is no single duration for every product. Some require repeated application or a specific activation routine. Follow the instructions for the exact solution you choose.

Can I keep my frames when replacing my lenses?
