Myopia ( Shortsightedness )
Vision is clear for near objcts and blurry for distant ones. Myopia can occur at any age but often begins during the teenage years.
When it occur at a very young age, visual development is not usually hindered as the child can do close tasks happily and much of their interest is in objects nearby. It is often not until school blackboards need to be read that blurred distance vision becomes a problem. Once a driving licence is sought significant myopia must be corrected. Spectacles, contact lenses or reflective surgery may correct myopia.
Even the cause is not confirmed, to many cases, an early detection with proper prescription can make life easier. And there is a special lens called myopia-control lens can help to hold the progress, too.
