Interestingly in some lesser known parts of Asia I was able to get a prescription using a machine that looked into my eyes and dynamically adjusted focus a number of times and then printed out the result in a few seconds (without me saying anything). This was followed by a quick scan of my eyes to look for abnormalities and a cheap pair of glasses was ready the same day.
The same prescription result was gained by a UK optician a couple of years later requiring half an hour of me trying to work out just which image I could see clearer.
I was also able to get lenses for frameless glassess in several asian countries (not in big cities) that were impossible to be replaced in the UK at any optician. When they asked where they had last been replaced they were surprised when I told them a small back street optician in Cambodia.
