Myopia, Hyperopia and Astigmatism Explained

The names of eye conditions can sometimes be confusing, not to mention completely baffling when it comes to understanding what each conditions means. When it comes to nearsightedness, farsightedness and astigmatism, tons of people aren’t quite sure of the differences between the conditions. If you’re confused about what each one does, you are not alone.

To make the explanations simpler, there is a video that you can watch that not only explains the differences, but also gives a short demonstration of each condition side by side with perfect vision. The video is pretty informative, but seeing the demonstration of each eye problem next to perfect vision image is a an eye opening experience!


Emmetropia is a word you may have never even heard before. It is the name for perfect vision. A person who has it can see clearly up close and at a distance. In the video, a person’s vision with emmetropia is displayed next to myopia, hyperopia and astigmatism at the end of each segment.


The doctors call it myopia, but there is a good chance that you call it nearsightedness. Myopia usually occurs because the eye is slightly elongated. This causes the light that enters the eye to fall on the wrong part of the eye. The light should focus on the retina, but instead it comes to a focus in front of the retina, causing the image to be blurred.

People who suffer from myopia can develop it from genetics and eyestrain. It is often discovered in childhood, but it can develop any time. For many sufferers, it levels off and their eyesight maintains a relatively stable amount of distortion. Others will see a continuing decline in their condition.

Myopia usually causes blurred vision. Someone who is nearsighted can typically see things clearly up close, but have trouble with objects that are at a distance. For instance, a person with myopia might have trouble reading the scoreboard at a football game when they are sitting in the bleachers and the scoreboard is in the end zone.

To correct myopia, most doctors recommend vision correction through the use of prescription glasses, contacts or vision correction surgery. But, here at Rebuild Your Vision, we say that’s hogwash! There are natural vision improvement methods which include a better diet and eye vitamins.

Hyperopia is also known as farsightedness and it usually occurs when the eye is shorter or smaller than normal. It causes the light which enters the eye to focus behind the retina instead of on the retina. This leads to the image appearing blurred. People who suffer from hyperopia have a hard time seeing objects up close. This means reading, computer usage and texting are more difficult tasks. People with hyperopia can usually see objects at a distance clearly.

The symptoms of hyperopia include blurry vision, discomfort, eyestrain and rubbing the eyes. To correct hyperopia, again, most doctors prescribe contact lenses or glasses. Sometimes these vision correction aids only have to be worn if the sufferer is doing close work like reading or working on a computer. They also suggest vision correction surgery. But, just like myopia, there are natural methods to prevent and treat farsightedness, including changing your diet and incorporating eye exercises into your daily routine.


Astigmatism is the term used by both doctors and the public for this eye condition that is the result of the cornea or the lens having an irregular shape. This irregular shape causes the light that enters the eye to focus on two separate points. A person with perfect vision has a single focus point which lands directly on the retina. Having two separate focal points results in blurry vision.

The symptoms for astigmatism are similar to other eye conditions. It causes headaches, eyestrain and mild blurring if there is a small amount of astigmatism. If there is a large amount of astigmatism, then there is significantly distorted vision. There is no definitive evidence as to what causes astigmatism, but there does seem to be a component of heredity to it. It often occurs along with either hyperopia or myopia. Astigmatism can get better over time or it can get worse; there are many variables to the condition.

Astigmatism is usually addressed by prescribing glasses to correct the vision. The glasses are not only intended to correct vision, but relieve the eyestrain, visual fatigue and headaches caused by eyestrain. Just like myopia and hyperopia, you can take steps to prevent or diminish the effects of astigmatism. Naturally vision therapy is also useful in the treatment. Eye exercises and diet are the keys to this type of therapy.

Natural Vision Therapy

Myopia, hyperopia and astigmatism can all be treated through natural vision therapy or training. As mentioned above, it generally consists of eating a healthy diet and doing regular eye exercises.
