Causes of Blurry Vision

Blurry Vision

Do you every worry about going blind?  Do you wonder if your decreased vision is due to a serious eye disease?  Blurry vision is a loss of sharpness or foggy vision.  Your vision difficulties may be in one eye or both eyes.  It may fluctuate or be constant.

Blurry vision may not always be due to an eye condition.  A migraine headache can sometimes cause blurry vision.  It can also be due to a stroke or mini stroke (TIA).  Also, certain oral medications can sometimes contribute.

Dr. Stanley Grandon, Dr. Cindy Wang and I can perform a thorough eye examination to determine the cause of you blurry vision and offer solutions to improve the quality of your vision.

Causes of Blurry VisionBlurry vision

  • Refractive errors (need for glasses or contacts)
  • Cataracts
  • Dry eyes
  • Macular Degeneration (ARMD)
  • Late stages of glaucoma
  • Diseases of the cornea
  • Diabetes
  • Floaters
  • Eye drops

Sometimes your visual complaints can be corrected with glasses or contact lenses.  The first part of a comprehensive eye examination is checking to see how much the vision can be improved with glasses.  Your vision may be blurry if your are near sighted (myopic), far sighted (hyperopic), or need glasses for near activities (presbyopic).   If you prefer not to wear glasses, Dr. Stanley Grandon and I can perform an evaluation to see if you are a candidate for LASIK or EPI-LASEK.

Cataracts usually cause gradual decreased vision in one or both eyes.  Most people develop cataracts with age.  Cataracts can be removed with surgery if they are interfering with your vision in your day to day activities.  We perform cataract surgery at the Dearborn Surgical Center.

Dry Eyes usually causing fluctuating vision.  If your vision improves with blinking or with insertion of a lubricant eye drop, you may be suffering from dry eyes.  Dry eyes may cause worse vision later in the day.  There are many treatments that Dr. Stanley Grandon, Dr. Cindy Wang and I can offer to treat your dry eyes.

Macular Degeneration (ARMD) can can the central vision to blur.  This can be diagnosed with a dilated eye examination.  Macular degeneration becomes more common with age.  There are two broad categories of macular degeneration, dry and wet.

Glaucoma does not usually cause blurry vision or any vision symptoms at the early stages.  Glaucoma affects your peripheral vision and at the late stages can affect your central vision.  Since glaucoma often has no symptoms, it is important to maintain regular eye examinations especially as you age.

Diabetes can cause fluctuating vision when the sugars fluctuate to high levels.  The often occurs if your blood sugar is poorly controlled.  Over time, diabetes can cause the vision to blur due to damage it causes to the eyes.

A floater can cause a moving blurry spot in the eye.  It is caused when the eye ages and the jelly like substance that fills the back of the eye (vitreous) liquifies.   The vitreous may clump together and you notice a floater moving around in your vision.  If you think you have a new floater it is important to have a dilated eye examination to ensure there is no tear or detached retina.

There are many causes of blurry vision.  It is important to have a thorough, dilated eye examination to determine the cause of your complaints.
