Differences between myopia, astigmatism and hyperopia

Myopia, astigmatism, and farsightedness are eye diseases that are very common in the population, which are different from each other and can still happen at the same time in the same person.

While myopia is characterized by a difficulty in seeing objects from a distance, hyperopia consists of the difficulty of seeing them closely. Stigma makes objects very blurry, causing headaches and tired eyes.

1. Myopia

Myopia is an inherited disease that causes difficulty in seeing objects from far away, causing the person to present blurred vision. Generally, the degree of myopia increases until it stabilizes around age 30, regardless of the use of glasses or contact lenses, which only correct blurred vision and do not cure myopia.

What to do

The myopia has healing, in most cases, through laser surgery, which can correct the degree completely, but that aims to decrease the dependence of correction, either with glasses or contact lenses. Learn all about this disease.

2. Hyperopia

In hyperopia, there is a difficulty in seeing objects close up and it happens when the eye is shorter than normal or when the cornea does not have enough capacity, causing the image of a certain object to form after the retina.

Hyperopia usually arises from birth, but may not be diagnosed in childhood and may cause learning difficulties. It is therefore important to have a vision test before the child enters school. See how to tell if it is farsightedness.

What to do

Hyperopia is curable when there is a surgical indication, but the most common and effective treatment is the glasses and contact lenses to solve the problem.

3. Astigmatism

Astigmatism makes the vision of objects very blurry, causing headaches and eye fatigue, especially when it is associated with other vision problems such as myopia.

Astigmatism usually arises from birth, due to poorly formed cornea curvature, which is round rather than oval, causing light rays to focus on various sites of the retina instead of focusing on only one, the image less clear. See how to identify astigmatism.

What to do

Astigmatism is curable and eye surgery can be performed, which is allowed from the age of 21 and usually causes the person to stop wearing glasses or contact lenses to see correctly.
