OWNDAYS Siam Center
Unit M22., M Fl, M Fl, 979 979 Rama I Rd, Pathum Wan, Bangkok 10330
OWNDAYS works on one figure: frame plus standard lenses at any power, included from the start. The Siam Center branch sits on the Fashion Galleria floor and gets busy on weekends when BTS Siam foot traffic peaks. Go on a weekday if the queue matters to you, since the 20-minute turnaround is only useful when you are not spending it waiting.
BTS Siam Exit 1 deposits you inside the mall without a single outdoor step. OWNDAYS occupies Unit M22 on the M Floor, the level Siam Center designates as its Fashion Galleria tier. The 20-minute glasses promise — the same one the brand introduced to Thailand in 2015 when it opened its first local store at Mega Bangna — is what the branch is built around.
The pricing logic is straightforward. Every frame in the store, starting at THB 1,990, includes a pair of high-index aspheric lenses manufactured to Japanese standards: 99% UV protection and anti-dust coating come standard, not as paid add-ons. Optional upgrades exist — blue light filtering, progressive correction, polarized, transitions, anti-fog, myopia control — but the base transaction is genuinely all-in. CleverThai's editorial guide to Bangkok eyewear stores specifically calls out OWNDAYS' pricing model as the reason the brand draws repeat customers across the city.
The frame selection runs to approximately 1,500 styles. Beyond new glasses, the branch also handles lens replacement — bring frames from any other retailer and they will fit new lenses from THB 1,990. A remote eye test can be booked online before you visit, which trims time at the counter. Color contact lenses are stocked alongside prescription frames.
The store runs 10 AM to 10 PM daily, matching Siam Center's operating hours. Weekend afternoons get congested: BTS Siam is the main interchange for the Sukhumvit and Silom lines, and the foot traffic feeds directly into the mall. If the 20-minute turnaround is a priority rather than a coincidence, aim for a Tuesday or Wednesday morning. The staff works across multiple languages, which matters for prescription consultations where precision in communicating your correction matters.
