Astigmatism is a Condition
Astigmatism is a Condition
not a disease and is more common than one might think.
A Brazilian study encounter that just about 24% of their students in one city had an Eye Astigmatism.
Astigmatism In Children in the United States, is about 3 out of 10 children have it. In Bangladesh, roughly 1 in every 3 adults older than the age of 30 had it, which counts for roughly 32.4% of the population.
Astigmatism is a condition where the eye, or rather the front of the eye also known as the Cornea, is oddly shaped. A natural cornea should be shaped like a sphere or the shape should be generally round.
People who have this condition have their corneas shaped a little more out or a little more inward, like the shape of a football or the back of a spoon. This in turn brings in more light points for the eye to focus on and it therefore confuses it. This causes Blurry Vision and due to the inability to see things clearly, can start to cause headaches and even migraines.
To correct, fix, or Treat Astigmatism it greatly depends on whether there are other signs of Eyesight Problems and what degree the condition is at.
If the person does not show any signs of any other Vision Problems like Myopia also known as nearsightedness or short sightedness vision, or Hyperopia also known as farsightedness or long sightedness vision, then there is no need to go through corrective measures when the person has very slight astigmatism.
Prescription Glasses and Contact Lenses are often given to adults who are experiencing symptoms such as headaches (as mentioned above), vision distortions, any eyestrain, and if adults constantly find the need to Squint or tilt their head to read signs or books.
The lenses that sharpen vision and make them clear again are often called Toric Lens. These Toric Lenses for Astigmatism have an extra power element to help bring all the scattered light that the original eye is processing into one solid direction.
This greatly helps Protect Your Eyesight and restores it to its natural state. These lenses are often very comfortable to wear and come in soft lenses. Not too long ago they were only available as very strict gas permeable form and could not be worn for long periods of time.
Laser-Eye-Surgery is also a valid option for completely Treating Astigmatism.
There are various surgical methods a person can undergo depending on how advanced their astigmatism is, the most popular of these include Laser-Assisted In Situ Keratomileusis (LASIK) and Photo-Refractive Keratectomy (PRK).
LASIK uses a laser to cut through the surface of the cornea and discards any dead or alive tissue from its underside. In removing this tissue, it greatly allows for better light to be transmitted through the eye, which results in the patient being able to see a more crystal clear image. The PRK surgery involves almost the same methods. PRK uses a laser to also remove tissue, but this laser removes it from the very front of the cornea.
This helps shape the cornea to be more round instead of football shaped and helps bring in the correct amount of light into the eye. Now you know that astigmatism is a condition.
