These days, as society develops, modern technological devices and machines take up most of the time in life, work and study. Accompanying the development and modernization of machinery and equipment is the decline in eye health from everyone from children to adults. Among them, astigmatism is one of the eye diseases that is trending towards rejuvenation and is a top concern today. To correct it effectively, first of all, everyone should know what astigmatism is?
What is astigmatism?
The eyes are considered the “windows to the soul” of each person. This helps us see and observe things and events visually with images and colors. Eye diseases or problems are therefore always of great concern to everyone. Among them, eye refractive errors today tend to increase in almost all target groups.
Astigmatism is a fairly common eye refractive error, also known as Astigmatism syndrome. When the eye is disordered, the cornea has an abnormal shape, causing images entering the eye to not be focused on the retina, causing the resulting image to be distorted and blurred.
There are 2 types of astigmatism:
- Cornea astigmatism is a condition in which the cornea is misaligned
- Lens astigmatism is a condition in which the lens is misaligned
People with astigmatism cannot recover on their own, but can change the severity of the astigmatism over time if they know how to properly protect, care for, and treat.
Causes of eye astigmatism
The cause of eye disorders is the deformation of the cornea. The cornea has a curved shape like an air balloon, and light rays entering the eye converge at different points (possibly before or behind the retina), causing this condition.
In addition, some of the following factors are also causes of eye disorder:
- Due to genetics: family history of having relatives with astigmatism, especially in families where both parents have the disease, the risk of astigmatism is very high.
- Eye damage due to corneal scarring or eye trauma
- Premature children are also at high risk of developing astigmatism
- Age. Elderly people have a higher risk of astigmatism than young people.
Symptoms of astigmatism
If the eyes have the following abnormal signs, people should have their eyes checked and examined at a medical clinic. Reputable clinics/hospitals:
- Blurred vision, blurred, blurred or distorted images
- Difficulty seeing at any distance.
- Double vision, seeing an object with two or three blurred shadows.
- In addition, there are some accompanying signs that may occur such as eye strain, watery eyes, headache, neck pain, shoulder pain,… aligncenter”>
Symptoms of astigmatic eyes Diagnosis and treatment of astigmatic eyes
Diagnosis
To determine whether or not your eyes have a disorder, you should check and visit reputable, specialized hospitals/clinics to ensure safety and have a solution. suitable treatment. Diagnosing astigmatism requires several tests:
- Vision test
- Refraction test
- Checking corneal curvature
- Check the ability to focus light
Diagnosis of astigmatic eyes Treatment
Treatment of astigmatism helps reduce the severity or dangerous complications that may occur. Measurespopular treatment:
- Using prescription glasses: this is the most popular method and is chosen by most people. The method has many advantages suitable for most subjects: simple, highly effective, leaving few complications. Patients should not wear glasses on their own but should see a doctor to choose the right type of glasses for their level. The astigmatic lens is designed in a spherical shape to help the collected light rays gather at 1 point, improving the patient’s vision level.
- Cornea surgery: this method is often applied to severe cases or when using glasses is not effective. This is a method that uses a laser or microsurgical knife to permanently reshape the cornea. Most common: corneal stroma shaping refractive changes (Lasik), epithelial keratectomy refractive changes (PRK), subepithelial flap keratoplasty refractive changes (LESEK).
- Ortho-K (Orthokeratology): This is a treatment using specially designed, rigid contact lenses to help correct the shape of the cornea. These glasses are used to wear at night to improve good vision the next day.
Prevent eye astigmatism
For hereditary astigmatism, it cannot be prevented. However, the severity can still be reduced and those who have not been affected should avoid it by:
- Avoid possible eye damage
- Working, studying, especially when using electronic devices, should be in well-lit places
- Avoid unfavorable light sources, too strong and dazzling light sources
- Take time for your eyes to rest and relax
- Early treat eye diseases (if any), avoid complications of astigmatism
- Check and examine your eyes regularly
- Supplement nutrition and nutrients that are good for the eyes through food and appropriate nutrition. Some nutrients that are good for the eyes are omega 3 (fish, fish oil, vegetable oil, nuts,…), vitamin A (gac, carrots, tomatoes,…)
Prevention of eye astigmatism Here, everyone hascan grasp the information to answer “What is astigmatism?” We hope that everyone realizes the importance of eyes to keep bright and healthy eyes, prevent eye refractive errors, and stay away from astigmatism. It is important that people find the address of the clinic, a reputable address for examination and treatment to ensure safety for the health of the “window to the soul.”
