What is astigmatism? Causes, symptoms and treatment

Astigmatism is a common vision problem caused as a result of corneal dysfunction. In the case of astigmatism, the cornea, or cornea, which is the next level of the eye, is an irregular rotation.

What is astigmatism?

The two main types of persistence are cornea and lens. Stigmatism of the cornea occurs when there is a defect or defect in the cornea. Lens stigma occurs when the lens is distorted.

Astigmatism is sometimes called irregular or irregular. Permanent stability occurs when the eye is not completely bent. Thus, instead of being round, it can be oval. This often leads to blurred and distorted vision.

Astigmatism is caused by improper rotation of the lens or cornea of ​​the eye that prevents light from focusing on the focus of the retina. The result is blurred vision or blurred vision. The example of Alyssa Kiefer.


What is the reason for the astigmatism?

It is not known what causes tyranny, but genetics is an important factor. It usually exists at birth but can develop later in life. It can be the result of an eye injury or even after eye surgery. Astigmatism is usually accompanied by myopia or myopia.

Sometimes, however, a rare condition called keratoconus causes astigmatism. This eye disease affects the cornea, causing the transparent tissue on the cornea to thin and swell. It causes blurring or dimming and sensitivity to bright light. The cause of keratoconus is also unknown, but it is also considered hereditary.

Although low light reading can make it difficult to focus the eyes, it does not impair your vision nor cause astigmatism. However, if you already have stability and are reading in low light, you may notice an increase in blur.


What are refractive errors?

Astigmatism is a type of anxiety disorder. These are common eye diseases that make it difficult to see clearly. The shape of the eye is unable to bend light properly, and as a result, vision may be blurred, blurred, or skewed.

Myopia: Myopia (myopia) is a type of refractive error that causes distant objects to fade or deteriorate. Other symptoms may include headache, eye strain and crooked eyes. Myopia occurs when the eye covering is too long, or the cornea is too curved.

Farsightedness: Hyperopia, on the other hand, is not able to focus on close objects - but you are able to see distant objects clearly. This vision problem occurs when the eyeballs are too short, or the cornea is not curved enough.


Who is at risk for perseverance?

  1. Astigmatism can occur in children and adults. If you have one of the following, you may be at higher risk of developing perseverance.
  2. Family history of astigmatism or other eye diseases, such as keratoconus (corneal degeneration)
  3. Corneal staining or thinning.
  4. Excessive myopia, which causes blurring of distance.
  5. Excessive foresight, which creates blurring.
  6. History of certain types of eye surgeries, such as cataract surgery


What are the symptoms of astigmatism?

Signs of perseverance can vary from person to person. Some people have no symptoms. The main symptoms of astigmatism include:

  • Blurred, distorted or blurred vision at all distances (near and far)
  • Difficulty seeing at night
  • Eye fatigue
  • Dizziness
  • Eye irritation
  • Headache

See a doctor if you have asthma symptoms. Some symptoms may be due to other health problems or vision problems.


How is astigmatism diagnosed?

An optometrist or ophthalmologist diagnoses asthma through a thorough eye examination.

An optometrist is a doctor who diagnoses vision problems and eye diseases.

An ophthalmologist is a specialist who gives clinical and careful treatment to vision issues and eye illnesses.

An ophthalmologist is a doctor who provides medical and surgical treatment for vision problems and eye diseases.

There are a number of tests that optometrists and ophthalmologists can use during eye exams to diagnose this.


Visual acuity test.

During a visual acid test, your doctor will ask you to read the letters in the table at a certain distance to see how far you can see the letters.

Refractive test A refractive test uses a device called an optical refractor. The device has a number of corrective glass lenses of varying intensity.

The doctor will ask you to read a chart by looking at the lens at a different intensity on the optical refractor. Eventually they will get a lens that fixes your Contact accordingly.

The only part of the optical version that has to do with stability is the cylinder and the spindle. The cylindrical part of the prescription measures the degree or degree of irregularity. Doctors use axial measurements to determine the position of the eye on the cornea.


How to treat consistently?

A mild case does not require treatment. Your doctor may cause vision problems in one of the following methods.

Repair glasses: Glasses and corrective contact lenses are the most common and least invasive treatment prescribed by a doctor.

Orthokeratology (Ortho-K): Orthokeratology (Ortho-K) is a treatment that uses a rigid contact lens to temporarily correct the irregular rotation of the cornea. You will wear tight contact lenses for a limited time.

Refractive surgery: If you have a serious problem, your doctor may recommend fracture surgery. This type of surgery involves the use of lasers or small knives to reshape the cornea. This will permanently correct the astigmatism.
