farsighted with nearsighted astigmatism

Myopia and hyperopia

Is both myopia , and the length of consideration , common problems that affect the safety of eyesight, known as myopia not to a person 's ability to see distant objects clearly despite its ability to see objects nearby clearly And short-sightedness is one of the very common problems, as nearsightedness is estimated to be approximately 30% of the US population, and there are a number of different ways to treat this condition. Close objects are clearly visible while distant objects can be seen clearly, and the severity of farsightedness varies according to the eye's ability to focus On close objects, and in some severe cases, a person can only see objects clearly from very distant objects, and farsightedness can be treated in a number of different ways.

Symptoms of myopia and symptoms of farsightedness

Nearsightedness

Most cases of nearsightedness are diagnosed during childhood , between the first school years and adolescence , through some of the symptoms that may appear in children if they are nearsighted, such as increasing the tip of the eyes, sitting near the TV and in the front seats in the classroom, Not noticing distant objects, and constantly rubbing their eyes. As for other symptoms that may appear on people of different age groups and people with short sightedness, we mention the following:

Incidence of headaches as a result of eye strain.
Difficulty seeing while driving the car, especially at night.
The need to focus, or close part of the eyelids, to see clearly.
Blurred eye when looking at distant objects.

Farsightedness

Farsightedness is associated with a number of different symptoms, including the following:

Eye fatigue, pain in the eye or the surrounding area, and a burning feeling in the eye .
Seeing near objects in a blurry shape.
The need to focus to see objects clearly.
Having a headache, or feeling tired eyes when doing some tasks that require looking at nearby objects for a long time, such as reading, writing, drawing, and using a computer.

Complications of myopia and farsightedness

Short-sightedness or farsightedness may be associated with a number of different health and physical complications, including the following:

Eye strain: Untreated, short-sightedness or farsightedness may lead to the person's need to increase focus when looking, which may lead to headaches and eye strain.
Squint: Some children with farsightedness may suffer from strabismus , and it should be noted that this problem can be treated by wearing a special type of medical glasses.
Other vision problems: Severe nearsightedness may lead to some other vision problems, such as cataracts or cataracts, glaucoma or glaucoma , and retinal detachment .
Impact on the ability to do some activities: Shortness or farsightedness affects a person's ability to do some daily activities, and it may limit a person's ability to engage in some recreational activities.
Safety related damage: Eye problems may affect the safety of the person and the people around him, especially if he is driving a car or operating some types of vehicles and heavy machinery.
Financial burden: The incidence of a vision disease increases the financial burden due to the increase in the need for some vision tests, and the price of treatment such as glasses, lenses , and surgeries.

Treatment of myopia and farsightedness

Prescription lenses

Short-sightedness or farsightedness can be treated by prescribing the appropriate lenses for the patient's condition, as these lenses are based on correcting the excessive curvature of the cornea in the case of myopia, or the weak curvature of the cornea in the case of farsightedness, and among the types of medical lenses that can be used in the treatment of vision problems The following:

Medical glasses: It is one of the simple and safe ways to treat vision problems, and there are many different lenses that can be attached to medical glasses to correct vision problems .
Contact lenses: These lenses are placed directly on the eyes, and come in many different designs, and there are some negatives and positives of these lenses that can be discussed with the doctor to determine the possibility of using them according to the person's condition.

Vision correction operations

During these operations, a laser beam is used to correct the shape of the cornea, whether by increasing its curvature or weakening its curvature. For some of these operations:

Modifying the shape of the cornea using a laser: This process is called the term LASIK and Acronym LASIK, during this process and is used as a laser beam to correct the structural problem in the cornea, this process is characterized by fast recovery, and escorted side symptoms less than others Other vision correction procedures.
Eradication of the corneal epithelium under laser - assisted: and Acronym LASEK, and is in the process of correcting the outer layer of the cornea only after removing part of the epithelial layer of the cornea, and then is replaced by the epithelial layer intact layer.
Eradication of the cornea refractors light: and Acronym PRK, the similarity of this method is the way LASEK but in this case is removed the entire epithelial layer is then correct the cornea shape using a laser, but not in this process , replacing the epithelial layer a new layer , but are left To grow normally and adapt to the new shape of the cornea.
