One pair, two looks. The Rongchy ED0008-BS uses photochromic lenses that stay crystal clear indoors and shift to a smoke grey tint in sunlight — an oval acetate frame that works as everyday glasses and sunglasses in one.
- Photochromic lenses — clear indoors, darken to smoke grey outdoors, fade back when you step inside
- Smooth oval silhouette — a retro rounded shape with subtle cat-eye lift at the temples
- Four curated colorways — Black, translucent Brown, translucent Grey and classic Tortoise
- Built for daily wear — reinforced hinges, 3D nose pads and non-slip curved temples
- Unisex fit — 142mm total frame width with 46mm oval lenses

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, Brown, Grey, Tortoise. All colourways share the same lens specification, so the choice is purely about how the frame looks on you.
Is the Acetate frame comfortable for all-day wear?
The acetate frame keeps total weight low, and the nose pads sit flat instead of pinching. Wearers who spend hours at a screen or in a book usually notice the difference on the bridge of the nose first.
Does Rongchy ship free, and what about returns?
Every order ships free worldwide with tracked delivery and no minimum spend. If the fit or the strength is not right, you can return the pair within 30 days of delivery for a refund or exchange.
How should I clean and store the lenses?
Rinse under lukewarm water, dry with a soft microfibre cloth, and skip paper towels or clothing, which leave micro-scratches in the coating. Keep the pair in its case when it is not being worn.
