[OWNDAYS] 10% off photochromic lenses! 28-day limited campaign!

OWNDAYS will be holding a 10% discount campaign on photochromic lenses for 28 days only from Monday, September 2nd to Sunday, September 29th, 2024!

Photochromic lenses change colour according to the amount of UV rays received.
The lens color will darken outdoors where UV rays are strong, and will change to a clearer color indoors where UV rays are weak.

These lenses are convenient because they serve two purposes: as glasses indoors and as sunglasses outdoors!


This lens is recommended for you!

- People who want to use the same pair of glasses for both everyday use and as sunglasses
- People who find it troublesome to put on and take off glasses and sunglasses when going out or traveling.
- People who want to reduce their baggage when camping or going outdoors

At OWNDAYS, we recommend lenses that are tailored to each individual customer's concerns.
Please come and try it out at our store.
