In this article, we will discuss the Medical Term For Farsightedness, Symptoms, Diagnosis, Treatment, and Prevention.
Medical Term For Farsightedness
Farsightedness or hyperopia is a close-up visual impairment. In hypermetropic people, distant objects are clearly visible, but close objects are not clear or blurry.
Infants and young children tend to experience hypermetropics, but the vision is not blurry. This condition is not to worry about, because the vision will be normal as the eye organs develop.
Hyperopia is different from presbyopia or old eyes, although these two types of eye refractive disorders cause the sufferer difficulty seeing close objects. Hyperopia occurs due to abnormal forms of the cornea and eye lenses, while presbyopia is caused by muscles around the lens becoming stiff due to aging factors.
Hyperopia can be classified based on its structure and function. Clinically, hypermetropia can be divided over simple hyperopia, where it is related to biological variation; pathological hypermetropia associated with abnormal curricular anatomy due to maldevelopment, curricular disease, or trauma; and functional hypermetropia due to paralysis of the accommodation.
Signs and symptoms
In the case of hypermetropics, the optics in the human eye are too weak, forcing your eye muscles to work harder for a clearer look. Patients with mild farsightedness may not experience any symptoms.
However, you can also experience farsighted features such as:
- Nearby objects appear to be blurry
- Pain around eyes or tired eyes
- Restlessness and fatigue
- Need to squint to see more clearly
- Headache or dizziness after reading
- Some children may experience strabismus (crossed eyes).
Most children who experience farsightedness do not feel symptoms such as blurred eye sight. As long as the farsightedness experience is not too severe, the child can still see objects far and near clearly.
Causes of Fartsightedness
The cause of farsightedness occurs through light entering the eye with no focus inside the retina, but focused on the back. This occurs because the cornea is too flat or less curved, the lens less thick and the eyeball short.
Some of the factors below that can cause farsightedness, including:
Farsightedness will often occur at the age of over 40.
Farsightedness is one of the diseases that can be inherited from parents or families.
The doctor can estimate farsightedness based on the symptoms complained about by the sufferer. A complete eye refractive examination can confirm hypermetropia. The doctor will also find out the size of the lens to correct your hypermetropia.
The refractive abnormality examination is carried out on one eye alternately, usually starting with the right eye then the left eye. This examination was carried out after a sharp examination of vision and it was known there was a refractive abnormality. Health workers also use certain screening tools to study what causes hypermetropia.
There are several things to overcome farsightedness, namely:
Glasses are used for people with farsightedness, in contrast to other glasses. Because farsightedness glasses have thicker ends, according to the severity experienced.
Contact lenses are used to treat farsightedness and have the same function as glasses.
Surgery is most reliable to overcome farsightedness, namely with laser surgery. Patients who have undergone laser surgery, there is no need to be hospitalized. But usually the sufferer should check himself back to the clinic or hospital.
Prevention of farsightedness
There are several ways you can prevent farsightedness, namely:
- Check your eyes regularly to the doctor.
- Pay attention to the lighting in reading, preferably the light from your back and top.
- Consumption of foods rich in nutrients, especially foods or beverages containing high vitamin A, such as green vegetables, carrots, fish, eggs, papayas, peppers, avocados, melons, peaches, apricots, mangoes, yams, milk, and so on.
- Use glasses with the right lenses according to the condition of each eye.
- Manage stress.
- Control blood pressure and blood sugar.
- Protect your eyes from direct sun exposure.
- Avoid smo**king and alco**hol consumption.
- Feel free to see a doctor if the condition does not improve or cause your discomfort.
