If the images you see are blurred, one or more of the following four conditions could be responsible.
If the images you see are blurred, myopia or nearsightedness could be responsible.
Technically known as hyperopia, people who are farsighted have blurred vision at all distances unless they make a constant effort to focus, which can lead to strain, headaches, and eye fatigue.
For people with astigmatism, all objects both near and far are distorted. Images are blurred because some of the light rays are focused and others are not.
Presbyopia is a natural occurrence in which the eye can no longer tightly focus up close. It commonly develops in people around age 40.
