Common questions
How do photochromic lenses work?
The lenses darken when UV light reaches them and clear again indoors, usually within 10 to 30 seconds in each direction. Because car windshields filter UV, they stay mostly clear behind the wheel.
Which colours can I order?
4 colourways are available: Black, Gold, Rose Gold, Silver. All colourways share the same lens specification, so the choice is purely about how the frame looks on you.
How does the frame feel after a few hours?
This pair uses a metal front with spring-loaded temples, so it flexes slightly instead of pressing. The weight sits across the nose pads rather than the ears, which is what makes long sessions bearable.
How long does delivery take, and can I return the glasses?
Orders leave our warehouse with tracking, and shipping is free regardless of order value. Returns are accepted within 30 days of delivery, so you can try the frame at home before committing.
What is the best way to look after the lenses?
Use lukewarm water and a microfibre cloth rather than tissue, which can dull the anti-reflective layers over time. Store the glasses in the case provided so the lenses do not rub against a hard surface.
