OWNDAYS Siam Square One
2nd Floor Siam Square One No, SS2011-SS2012, 388 Rama I Rd, Pathumwan, Pathum Wan, Bangkok 10330
OWNDAYS Siam Square One is the most centrally located branch of the brand in Bangkok, sitting inside one of the Siam BTS station's primary connected malls. The all-in pricing means the number you see on the frame is the number you pay, lenses included, and the 20-minute service keeps the whole transaction frictionless. A strong pick for anyone already in the Siam-Pathumwan shopping corridor looking to sort out new glasses.
Step off the BTS at Siam station and Siam Square One is practically underfoot. The mall connects directly to the elevated walkway, which means you can go from train to optical shop on the second floor at units SS2011 to SS2012 without descending to street level once. For a city where midday heat can make any outdoor detour feel like a commitment, that matters.
OWNDAYS opened this Siam Square One branch in March 2025, adding a Pathum Wan address to a Thailand network that spans more than 76 stores. The format follows the chain's proven model: a clean, well-lit floor of over 1,500 eyeglass frames organized by style, material, and collection, with every price tag reflecting the complete cost of the finished pair.
The pricing system is straightforward. Select a frame, and the amount shown includes a pair of high-index aspheric lenses manufactured by leading international optical producers. Standard prescriptions incur no additional charge. Every lens comes with 99 percent UV protection and a dust-resistant coating. Starting at 1,990 baht, the range climbs through designer-adjacent frames, acetate shapes, lightweight titanium options, and seasonal collaboration pieces.
OWNDAYS processes most standard orders within 20 minutes, with the in-house lab handling cutting and fitting on site. This turnaround makes the Siam Square One branch particularly useful for travelers staying in the Pathum Wan area who want a quick prescription update or replacement pair.
Sunglasses with prescription lenses, lens replacements for existing frames, and walk-in adjustments are all available. The second-floor location inside Siam Square One puts you within the broader Rama I Road shopping belt that includes Siam Paragon and CentralWorld, both reachable via the same elevated walkway network from Siam BTS station.
