What Causes Farsightedness?

Farsightedness, also known as hyperopia, is a common vision condition in adults which allows you to see distant objects clearly, but nearby objects are blurry. With over three million cases per year, it’s appropriate to ask the question of what causes farsightedness and how can it be treated? Understanding the difference between hyperopia and the normal eye is easy, and in this blog, we’ll explain both.

Signs of Farsightedness

Individuals with hyperopia have to squint to see nearby objects and it makes reading, writing and a long amount of time on the computer tough and can cause headaches and eye strain. Keep in mind, this vision problem can be serious and requires a medical diagnosis. Farsightedness or hyperopia is typically developed at birth and more times than not is within the family. Each farsighted case is different as it depends on your focusing ability. If you are having trouble seeing objects clearly, it may be time for an eye exam.

What Causes Farsightedness or Hyperopia?

So, you may be wondering, which condition may cause farsightedness? Farsightedness occurs when light rays entering the eye focus behind the retina, rather than directly on it. The eyeball of a farsighted person is shorter than normal. Often times, children who are born farsighted outgrow the eye condition. Now, not to get confused with nearsightedness as this is the opposite. When one is nearsighted, seeing objects up close is no problem, it’s focusing on images at a distance where blurred vision is taken into effect. Take a look at the differences of hyperopia and the normal eye below to see farsightedness causes.

Eyes without hyperopia not only have a larger eyeball, but images are focused on the retina. When images are focused on the retina, there is no blurred vision. As a result, light rays are focused on the retina vs. passed it.
