Myopia, also known as near-sightedness and short-sightedness, is a condition of the eye where the light that comes in does not directly focus on the retina but in front of it, causing the image that one sees when looking at a distant object to be out of focus, but in focus when looking at a close object.

When used colloquially, 'myopia' can also refer to a view on or way of thinking about something which is—by extension of the medical definition—hyper-focused and fails to include a larger context beyond the focus.
