What Is A Stigmatism In Your Eye? Eye Vision Problems


Do you know what is a stigmatism in your eye? Are you feeling you have eye vision problem? Go through this guide of symptoms of vision problem and its causes behind. The two most common vision problems are nearsightedness and farsightedness. While there are also other two which are astigmatism and presbyopia.

These are Refractive errors which occur when the shape of the eye prevents light from focusing directly on the retina. Refractive errors can be caused due to the change happen in length of the eyeball, changes in the shape of the cornea, or aging of the lens. These causes are very common which can be found in most of the cases.

How do we define Refraction?

Refraction can be defined as a light ray when bends at an specific angle while entering from one medium to another. In eyes, when light ray refract from an angle and it pass through cornea and lens, vision occurs. Then that light ray reaches retina where it delivers the message that are sent to brain through optic nerve. Once the message is sent to brain, the image is formed in brain and we can see the object.

what’s an astigmatism

Here are some common eye vision problems’ symptoms and causes.


When a person faces a vision problem in focusing on far objects: far objects appear blurred. However the near objects are clear to see so this vision problem is categorized as nearsightedness. Near sightedness problem is caused in eyes when focus images in front of the retina instead of on the retina consequently blurred vision develops. The reason behind is that the size of eyeball increases and become long therefore it stops incoming light to focus directly on the retina. The abnormal shape of the cornea or lens is also reasons of this vision error.

 signs and symptoms 

  • Headaches
  • Eyestrain
  • Squinting
  • Difficulty seeing distant objects, such as highway signs



Just an opposite of nearsightedness, when the far objects are clear but the close objects get blurred. If the person is not able to see near objects clearly then he must be facing refractive error known as farsightedness. Some people have different case as at young age specially they doesn’t face any issue of vision. Farsightedness however when gets significant, vision can be blurry for objects at any distance, near or far. When focus images behind the retina instead of on the retina it results in farsightedness hence eye can develop blurred vision of object.  It happens when the eyeball becomes too short and it prevents incoming light from focusing directly on the retina. Also by an abnormal shape of the cornea or lens, farsightedness can be caused.

Signs and symptoms

  • Headaches
  • Eyestrain
  • Squinting
  • Blurry vision, especially for close objects
  • Blurred vision


what is a stigmatism in your eye? It is another common problem of eye comes under refractive error. When a person’s eye does not focus light evenly onto the retina, the light-sensitive tissue at the back of the eye then he suffers from astigmatism.

When light is not bent adequately rather differently depending on where it strikes the cornea and passes through the eyeball. Normally a perfect eye has cornea with a shape like basket ball that means from all sides of cornea the roundness is same however the eye suffering from astigmatism has a cornea that is curved more like a football that has some steeper or more rounded areas than others. This results in images to appear blurry and stretched out.

Signs and symptoms

  • Headaches
  • Eyestrain
  • Squinting
  • Distorted or blurred vision at all distances
  • Difficulty driving at night


It is a common type of vision disorder that occurs as you age. It is often referred to as the aging eye condition. Presbyopia results in the inability to focus up close, a problem associated with refraction in the eye.

Presbyopia is a common problem of eye vision which happens naturally with the growing age. The eye gets weak and it is not capable enough to focus light directly on to the retina because the natural lens of eye gets hard. Muscle fibers around the lens become harder due to aging and therefore it becomes difficult for the eye to focus on up close objects. The light focuses behind the retina which results poor vision for objects that are up close thus it means the lens of eye has become ineffective.

At young age, the lens of the eye is soft and flexible therefore the tiny muscles inside the eye can easily reshape the lens to focus on close and distant objects but the aging effect this natural process of vision.

Signs and symptoms

  • Hard time reading small print
  • Having to hold reading material farther than arm’s distance
  • Problems seeing objects that are close to you
  • Headaches
  • Eye strain
