"Simple myopia is more common than other types of myopia and is characterized by an eye that is too long for its optical power (which is determined by the cornea and crystalline lens) or optically too powerful for its axial length.[7] Both genetic and environmental factors, PARTICULARLY SIGNIFICANT AMOUNT OF NEAR WORK, are thought to contribute to the development of simple myopia.[7]"
