Exam to determine: Myopia can occur from the eye being "large" or long. This is referred to as axial myopia-the most common form. It can also occur from a high index of refraction in the lens, as with cataracts, or a very steep cornea, as with keratoconus. You need an exam to determine these factors.

Eye exam will tell.: Axial myopia: eye length is too long for distance light rays to be focused on retina. Other common cause of this is a cornea that is too curved + over focuses the rays short of the retina. Pseudo myopia likely refers to a spasm of the inner lens over focusing the rays - detectable with drops that paralyze focusing muscle. No limit to level of myopia.
