Largely a Myth.
If you are genetically pre-disposed to be nearsighted it can make your sight worsen quicker. However, it will not have an effect on someone that does not have the genes for Myopia.
Some interesting tidbits about Genetics and Myopia....
Less than 1% of Africans are nearsighted, but almost 60% of Chinese and Japanese are. It has to do with selective pressures in the past. Nearsighted Africans likely did not survive long on the plains, while nearsighted Asian's were the scholars and passed on their genes.
Northern Europeans are actually more likely to be nearsighted as well.
