BANGKOK—Last week’s military coup in Thailand has not interrupted ophthalmic lens production in that country, according to industry sources. Although the situation there was still unstable at press time, three of the lens makers who operate lens manufacturing plants in and around Bangkok— Vision-Ease Lens, Essilor and Hoya Vision Care—told VMail that it’s “business as usual” there.

“Day to day operations are not impacted by the political situation in Thailand. We are continuing to monitor the situation closely,” said Bill Krueger, vice president of worldwide marketing for Vision-Ease Lens.

A spokesperson for Essilor said the situation in the Thai capital, Bangkok, remains “calm,” and that all of Essilor’s manufacturing operations, which are located more than 50 km from the city’s center, are continuing to run.

“A curfew has been imposed between 10 p.m. and 5 a.m., but our staff has been exempted, including factory workers for the night shift. The international airport, which is also located outside city, continues operating. Concerning the security of all our employees—including Thai employees and family expats—we follow the recommendations from the different embassies, meaning essentially respecting the curfew.”

Gerry Bottero, CEO of Hoya Vision Care said “The coup has had absolutely no effect on our production facilities, transportation routes and export operations from the Bangkok Suvarnabhumi airport. We continuously monitor this situation and report to our stakeholders twice a day. Our relations and commercial flow with customers and suppliers in Thailand have remained normal since the protests began in November 2013.”
