Astigmatism

Author: Erich Shrefler

If you have blurred vision when looking at objects up close, far away, and in between, it may be astigmatism. Astigmatism causes blurry vision due to an irregularly shaped cornea. Most people have some slight astigmatism but not always enough to cause vision problems.

Your Cornea and Astigmatism

Astigmatism is a type of refractive error. Your cornea bends, or refracts, light as it enters your eye to focus it on the retina. In order to properly focus the light, your eye needs to be spherical in shape. With astigmatism, the cornea is oblong or oval shaped, more like a football. When the irregularly shaped cornea bends the light it creates two or more focal points, rather than one clear focal point, causing the image to be blurry.

Recognizing Astigmatism

Astigmatism can occur alone or in combination with nearsightedness (myopia) or farsightedness (hyperopia). Symptoms include:

  • Distortions in vision making it difficult to make out fine details up close, far away, and in between
  • Blurred vision
  • Eye strain
  • Headaches

Children can be born with astigmatism, or the condition can be caused by trauma to the eye due to an injury or surgery. Keratoconus is a disease of the eye that causes progressive thinning of the cornea and can cause astigmatism.

If you are experiencing the symptoms of astigmatism or any change in your vision, it is important to see your ophthalmologist right away. These can be symptoms of a more serious eye condition or health problem.

Astigmatism in One Eye

When vision is different between your two eyes, your brain chooses the better of the two images, ignoring the bad eye. The eyes do not work together properly and depth perception is affected.

In young children, whose brains are still developing, astigmatism in just one eye can cause lazy eye (amblyopia). Left untreated amblyopia can cause permanent vision loss in the affected eye.

Correcting Astigmatism

Eyeglasses or contact lenses are typically prescribed for people with astigmatism. In the past, soft contact lenses were not an option for astigmatism. Today there are soft contacts available for astigmatism, but they are more difficult to make and cost more than other soft lenses.

Corrective lenses improve your vision while you wear them, but they do not truly correct the astigmatism. Refractive surgery, such as LASIK or PRK, reshapes your cornea correcting the refractive error. If you are also nearsighted or farsighted, the surgery can correct that at the same time, giving you clear vision without the need for glasses or contacts.

    What can cause blurred vision in one eye?
    I sometimes (not any time recent) have blurred vision in a single part of a single eye. Usually the right eye and its usually only the upper right hand corner of that eye but its impossible to see anything in that section (about half the eye). I sometimes feel a slight headache with them, but not always and it goes away after about 10-30 min. I was just thinking about it and maybe someone out there knew what it was. It doesnt seem like a serious problem im just curious.

    Can sinus pressure cause blurred vision in one eye?
    I’ve had a bunch of sinus pressure lately. I’ve been having random sinus headaches in my left temple, and for the past two days those headaches have been accompanied by blurred vision in the same eye. I’ve had sinus issues most of my life and never experianced this before. Even after my headache goes away, the blurred vision remains.

    I don’t have any health insurance, so I’m mainly wanting to know if this is normal as a symptom of sinuses or not.

    what can cause blurred vision in one eye suddenly?
    Yesterday I had a migraine all day and all of a sudden my left eye went completely blurry and has been this way since. the headache went away as soon as my left eye went blurry.

    • Bolt says:

      You need to see a doctor, soon

      the pain and resulting blurriness in only one eye (especially if it releived the headache) could be a symptom of a serious problem that needs attention

    What Can Cause Blurred Vision in One Eye?
    I was cleaning and all of a sudden in the left corner of my left eye I started to see double & blurred. I sat down cleaned my eyes with water to see if it went away. I did’nt I can look straight ahead with no prob. But when I turn to my right I can not see clearly out of my left eye. As I layed down to see if it went away I started to get a migrance like headache above my right eye and feeling like vomiting.

    Really Need to hear some real answers since I have no type of health insurance and cant see a doctor…Is this serious or will it go away?
    Wow Thanks so much for all the info… I do to get numbness and tingling in my thumb on my right side… I am go to the doctor for this because this is not the 1st it has happened to me…thx

      Sounds like an optical migraine. I get those sometimes. I have to lay down in a dark room and just wait for it to go away. Sometimes it lasts for a few minutes and other times it takes hours.

    Can anxiety cause blurred vision in one eye?

    I am 16 yrs old and have 20/20 vision. But i’ve noticed that when only looking through one eye(my left) it is worse than my right eye vision. It seems more blurred in my left.

    • Britter says:

      No.

      This doesn’t sound like an anxiety issue either.

      What you need to understand is that your eye doctor (optometrist) gives you the beset possible vision you can have when you have BOTH EYES open. Because that is what you use 99% of the time! You don’t walk around using one eye, do you? So what does it matter that your left eye is “worse” than your right eye?

      As long as you are seeing 20/20 together with both eyes, that’s all that is important to you.

      This is the case for many people; this is normal.

      But if you are really really concerned about it, you can make an eye appointment with your eye doctor to get it checked out.
