Myopia, astigmatism and hyperopia are very common eye diseases in the population, which are different from one another and can even occur at the same time, in the same person.
While myopia is characterized by difficulty in seeing objects from afar, hyperopia consists of difficulty in seeing them up close. Stigmatism causes objects to appear very blurry, causing headaches and eye fatigue.
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 can be cured, in most cases, through laser surgery, which can correct the degree completely, but which aims to reduce dependence on correction, whether with glasses or contact lenses. Find out everything about this disease.
2. Hyperopia
In hyperopia there is 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 certain object to form after the retina.
Generally, hyperopia appears from birth, but may not be diagnosed in childhood, which can cause learning difficulties. Therefore, it is important to have a vision exam before your child starts school. See how to know if it is hyperopia.
What to do
Hyperopia can be cured when surgery is indicated, 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 blurry, causing headaches and eye fatigue, especially when it is associated with other vision problems such as myopia.
Generally, astigmatism appears from birth, due to a malformation of the curvature of the cornea, which is round and not oval, causing light rays to focus on several locations on the retina instead of focusing on just one, making the image less clear. See how to identify astigmatism.
What to do
Astigmatism can be cured, and eye surgery can be performed, which is permitted from the age of 21 and which, normally, means that the person no longer wears glasses or contact lenses in order to see correctly.
