Boonteng Optical
593 11-12 Soi Sukhumvit 33/1, Khlong Tan Nuea, Watthana, Bangkok 10110
For expats who need a reliable prescription fill without navigating a mall optical chain, this is the clearest choice on Sukhumvit. The heritage is real, not decorative, and the English-language service is a genuine advantage. Personally, a shop that helped build the country's optical industry earns more trust than a franchise that opened last year.
Optical care in Bangkok in 1931 meant finding one of a handful of practitioners in a city without a formal optometry industry, let alone professional standards or a trade body. That is the environment Mr. Boonteng Lopansri entered when he co-founded what was then called Prachak Optical on Sukhumvit Soi 33/1. He and his partner Dr. Prachak split the practice deliberately: one managed the optical fitting and retail, the other the medical side. Mr. Boonteng went on to become the founding president of the Thai Optical Association and was the first optometrist in the country to introduce Essilor Varilux progressive lenses, a technology that at the time represented a significant shift away from bifocal correction. That combination of institutional leadership and product innovation set the shop apart from contemporaries that simply sold frames.\n\nThe offer today covers the full range you would expect from a serious independent: eye examinations, prescription lenses, contact lenses, and a curated selection of brand-name frames and sunglasses. Progressive lens fitting remains a specialty.\n\nThe shop sits directly opposite Benjasiri Park on the corner of Sukhumvit Soi 33/1. BTS Phrom Phong is a short walk. Sunday is closed; Monday through Saturday runs 9:30AM to 6PM.\n\nOne practical note: the review count is small for a 90-year-old business, which likely reflects that regulars don't feel the need to post. The prescription slip is in English, the price is in baht, and lenses are ready within a week.
