When purposefully using a lens to view the world in a certain way, always remember that there are more lenses you can use to see the world. Each new way of looking at things is useful in its way, but it is limited. These limits can only be overcome by using other lenses. The more lenses you use to see things, the less chance you'll have a blind spot.
abstract ideas, lenses, and mental models are all different views of the same concept. This is because all three of these are abstract ideas used to explain another idea.
