I went to the eye doector today and he said I was seeing -3.75 in my left eye which is a severe difference from my right eye and from my check up last year. I am only sixteen years old and he said that it is very uncommon for kids my age to have this. He is going to have me wear corrective lenses for two weeks and see if it gets any better. What could this be?

Thanks For all Serious Answers.

PS. He was acting all serious (opthomologist) and asking me when my last MRI was. (Last year and clean) Could this be important?
