A: As to the topic, we should know the importance of measuring OC firstly. And here is a quick way to find an optical center on a single vision lens,  if your foci meter happens to blow a bulb and you do not have a spare.

Position the lens in your hand and appearance through it through the room for a dark thin straight line, move the lens between the two horizontally before you see no movement, and draw a compact 1 inch line.

Now turn the lens 90 degrees and do the same principle, and hang up a dot on the line that you see no more movement, there may be your optical center, close enough to all intents and purposes.
