Presbyopia: what it is, symptoms, causes and treatment
More and more people are becoming aware of the importance of taking care of their eyes; and particularly not only the eyes, but above all at the time of taking care of the vision. And we must not forget that the eyes are very sensitive and delicate organs, so that any serious injury in them can even lead to loss of vision.
Over the years it is common for some common vision disorders to appear, such as cataracts (blurred or dull vision) or myopia (progressive but slowed vision loss).
In the case of presbyopia we are facing another of the most common vision disorders, which usually appears especially after 40 years of age.
What is presbyopia and what does it consist of?
It is characterized by being a disorder directly related to age; in fact, we can literally translate presbyopia as aged eye. It consists of an ocular condition, which appears after 40 years of age, when the lens tends to become more rigid.
It is an alteration of vision that we could call mechanical, since the crystalline lens can not change shape as easily as before, becoming more rigid. Hence, it is considered as a normal condition.
Symptoms of presbyopia
The most common symptom is difficulty reading or seeing things at close range. As a result of straining the eyes may appear other signs and symptoms, such as eyestrain, feeling tired when carrying out an activity that requires close up, and headache.
Causes of presbyopia
Medical experts believe that, as we get older, changes in the lens proteins make it more rigid and less flexible, while the muscles around it also lose elasticity.
Therefore as the years go by, and as the lens becomes less flexible, the eye has a greater difficulty to focus on nearby objects.
How is presbyopia diagnosed?
The ophthalmologist can diagnose presbyopia easily during a complete eye examination, and can determine the degree of presbyopia through a standard vision test.
This standard test consists in asking the person to read the letters in a table placed at the other end of the room, then evaluating the near vision.
Treatment of presbyopia
Since presbyopia is a normal condition that appears over the years, reading glasses (also known as reading glasses) can be very useful in easily correcting the symptoms of presbyopia.
The most common is that these glasses are only used during those activities in which it is required to see up close. They can be purchased in pharmacies and stores, although it is also possible to opt for glasses prescribed by the doctor, which are of higher quality.
