If you are finding that what you are looking at is blurred, one or more of the following four conditions could be responsible.
For a shortsighted person, close objects are clear, but distant objects are blurred and difficult to distinguish.
Technically known as hyperopia, people who are longsighted have difficulty seeing close objects; distant objects may be clear but up close objects appear blurry.
For people with astigmatism, all objects both near and far are distorted.
Presbyopia is a natural occurrence in which the eye can no longer focus near objects. It commonly develops in people around the age of 40.
