Sỹ Hoàng has three stores in Vung Tau. For a pretty good frame and lenses plus eye exam, I paid just $80.54 [2 million đồng], and they were super fast too. Walking in off the street, I was out of there in about 20 minutes. The guy told me I wasn't just near sighted but astigmatic. Leaving, I couldn't help but tell them, "Everything is immediately clearer!" My previous glasses I got in Busan, South Korea 2 1/2 years ago.
