Poor eyesight is hereditary. For example, some experts suggest that heredity is the most important contributing factor to nearsightedness. Glaucoma and diabetic retinopathy also tend to run in families. If your relatives have vision problems, make sure to see an ophthalmologist on a regular basis. Heredity, however, is only one of many factors that can affect your vision.
