A simple test for your level of myopia is to hold a ruler up to your eye, and measure how far away you can still read text without [[blur]]. If you measure this distance in centimetres, this is your "cm measurement". The ideal precise measurement is from the surface of your eyeball, but this is obviously not safe, so measure from some facial structure near your eye. Consistency is more important than accuracy, you want to be able to track your small changes over the course of a day, and larger changes over time. | A simple test for your level of myopia is to hold a ruler up to your eye, and measure how far away you can still read text without [[blur]].
