Myopia, astigmatism and hyperopia are very common eye diseases in the population, which are different between them and can still happen at the same time, in the same person.
While myopia is characterized by a difficulty in seeing objects from afar, hyperopia consists in the difficulty of seeing them up close. Stigmatism makes objects look very blurry, causing headaches and tired eyes.
1. Myopia
Myopia is a hereditary disease that causes difficulty in seeing objects from afar, causing the person to have blurred vision. Generally, the degree of myopia increases until it stabilizes around the age of 30, regardless of the use of glasses or contact lenses, which only correct blurred vision and do not cure myopia.
What to do
Myopia is curable, in most cases, through laser surgery, which can correct the degree completely, but which aims to reduce the dependence on correction, either with glasses or contact lenses. Find out everything about this disease.
2. Hyperopia
In hyperopia, there is a difficulty in seeing objects up close and it happens when the eye is shorter than normal or when the cornea does not have enough capacity, causing the image of a particular object to form after the retina.
Hyperopia usually arises from birth, but it may not be diagnosed in childhood and may cause learning difficulties. Therefore, it is important to have a vision exam before the child enters school. See how to know if it is hyperopia.
What to do
Hyperopia is curable when there is a surgical indication, but the most common and effective treatment is glasses and contact lenses to solve the problem.
3. Astigmatism
Astigmatism makes the vision of objects very blurred, causing headaches and eye strain, especially when it is associated with other vision problems such as myopia.
Generally, astigmatism arises from birth, due to a malformation of the corneal curvature, which is round and not oval, causing the rays of light to focus on several places in the retina instead of focusing on just one, making the least sharp image. 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 which normally causes the person to stop wearing glasses or contact lenses to be able to see correctly.
