Nearsightedness (difficulty seeing objects clearly at a distance)
Nearsightedness, or myopia, is an eye problem that causes objects at a distance to look blurry. Nearsighted people can see objects close to them clearly, but have a hard time focusing on objects that are far away. People with this eye problem often sit close to the television or bring books close to their eyes when reading.
In most cases, nearsightedness is inherited. However, some evidence suggests intense close-up activities, such as reading or playing video games for prolonged periods in early adulthood can induce myopia.
Myopia is treated with glasses, contact lenses or with laser procedures, such as LASIK. People with a low degree of nearsightedness may only need glasses for driving or watching a movie, while others with a high degree may only have clear vision a few inches from their nose.
