Is being nearsighted a genetic disorder?

Me, my mother, my grandmother, my father, ect. all have eyesight problems. my father is the only one that is farsighted. I'm doing a report on genetic disorders and my mother says I should do it on nearsightedness. Is nearsightedness a genetic disorder?

I would not call myopia a genetic disorder. A genetic trait, perhaps, but not a disorder. Chromosomal defects are one example of a genetic disorder.

Yes, it is a genetic disorder just like diabetes, or ect.

It can be. I have it...mine's from astigmatism, my mom has it.

The evidence to prove that nearsightedness is PURELY genetic is conflicting. They say that myopia or nearsightedness is a Recessive Genetic Disorder, which means that to present it you would need two recessive defective alleles of the gene, one from your mom and one from your dad. However, the scientific community also believes that in addition to the genetic inheritance there are environmental factors that make it more prevalent. There is strong evidence to believe that rapid, environmental induced change increases the prevalence of myopia, this is associated with increased education and urbanization. That means that people who live in the big cities are more likely to have myopia. Anyway, I hope this helps with your report. I know the answer is complicated but you could definitely ignore one side of the argument and focus on the genetic part of it.
