WHAT CAUSES POOR EYESIGHT?

While many factors can affect your ability to see clearly, poor eyesight occurs most often when the retina (the part of your eye where images are focused) no longer works properly — resulting in blurred vision. Eye experts say that your likelihood of developing poor eyesight is typically hereditary (meaning it’s something that’s passed down to you from your parents). Luckily, poor eyesight is an easy thing to correct with glasses or contacts.
