A jammed finger is characterized by pain and swelling usually due to an impact injury. It tends to be excruciatingly painful and instant treatment will help the joint heal faster. A majority of jammed fingers heal quickly, if there is no fracture.
Hypermetropia is also known as 'long-sight'. This means that a child who is 'long-sighted' is more likely to see better at 'long' distance than 'short'. Often children with Hypermetropia can see clearly when watching the television or the blackboard but may find reading a book difficult.
Myopia, also known as nearsightedness, is a common type of refractive error where close objects appear clearly, but distant objects appear blurry. Myopia often progesses throughout the teenage years when the body (including the eye) is growing rapidly.
