Hypermetropia means longsightedness. The person suffering from hypermetropia can see distant objects clearly but the near objects appear blurry ( reading newspaper or a book). This is generally caused by two factors:

i. Decrease in the size of the eye ball

ii. Decrease in the power of the eye lens
