Astigmatism is a common refractive error in which light is not focused properly on the retina, resulting in vision problems. It affects about one in three people in the U.S. and can affect both children and adults. If you have this condition, both near and far objects may appear blurred or distorted.
Digital eye strain, also known as computer vision syndrome, has been a recognized health problem for over 20 years. It involves a wide range of eye and vision-related conditions resulting from excessive exposure to digital devices.
