Can they replace my prescription glasses?

No. The designs in this selection are sold without prescription lenses and do not replace corrective eyewear. If you need correction, ask an eye-care professional about frame compatibility before considering replacement lenses; a prescription service is not included here.

Do all of them darken outdoors?

No. That feature belongs to models identified as photochromic, not to Blue Block filtering itself. Check the chosen pair and do not assume every lens changes tint with the same intensity or speed.

Will colours look exactly the same?

Identical colour perception cannot be guaranteed. The filter, tint and state of a photochromic lens can influence the view. For photography, design or colour-critical work, check suitability before using them to make colour decisions.

What is Blue Light technology?

Blue light (HEV) is emitted both by the sun and by LED screens and digital devices. Studies have shown that it can suppress melatonin — the hormone that regulates our sleep cycles — and is linked to symptoms such as eye strain, blurred vision and dry eyes. Our Blue Block technology works as a filter against this high-energy light.

Features:

UV Protection: UV400 (100% UVA and UVB) with integrated Blue Block filter.
Eye Fatigue: Reduces visual fatigue and strain during prolonged screen exposure.
Side Effects: Helps improve sleep quality and may reduce headaches.
Indoor Use: Lens designed for indoor environments or low-light conditions.

But when we go out, we go all in. Is the sun bothering you? We neutralise it.
You don’t need to change to go out, your photochromic frames and lenses already did it for you.

So do yourself a favour and never say no to a sunny plan.

What do photochromic lenses and frames offer?

Photochromic lenses and frames are made from special materials that react to ultraviolet (UV) light. When exposed to the sun, UV rays trigger a chemical reaction on the lens surface, causing them to automatically darken. This way, your eyes stay protected without the need to switch glasses.
