I got new long-distance (ie non-reading) specs a year ago at Bangkok Vision Center, Wattana (near Benjakiti Park). Couldn't be better.
Up steep stairs, small, friendly, spoke English, tested my eyes, discussion, laughed at my jokes, chose my frames (Essilor) from limited samples, glasses ready later that day, careful fitting, 7000฿.
One year later couldn't be happier with them.
