“In Costa Rica, the eye doctor apologized that a six-month supply of contacts would cost me USD 30 since I wasn’t on the national health insurance. It was the same brand I buy in the States for about USD 50 per month — with good insurance paying most of the cost. He said that if I were a resident, they would have been free; ‘So sorry you have to pay the high out-of-pocket cost.'”
“I had lost my glasses in the ocean on the first day of visiting relatives for a few months in Costa Rica. They called the local optometrist and got me in the same day (since I’m super blind). We were on the West Coast, and the glasses had to be shipped from the capital, which would take a few days, but the doctor said I could buy contacts off the shelf from them right then.”
