For your problem, I can say that lazy eye is not genetic. Lazy eye refers to the best corrected visual acuity is less than 0.9. It can be caused by obvious organic lesion formation or no obvious organic lesion. We know that good vision is not innate obtained, when the baby is born, the vision acuity is less than 1% of the normal people. With age growing, the binocular cells are constantly developing and improving. 1 to 5 years old is an important period of visual development, and visual development can be extended to 6 to 8 years old. If in this period, your vision can not have a normal development, visual cells have not normal stimulation, visual function remains in a lower level, and can not be corrected, and then it may make you have lazy eyes.
