Most of us have probably heard of the condition “cataracts”, but do we actually know what that means? Let’s talk all about cataracts!

What are Cataracts?

Cataracts are a condition that usually occur gradually as we age and leave our eyesight blurry or dimmed.  Normally, the lenses of our eyes allow a clear and focused image to pass through them.  However, a cloudy area may form on the inside lens of our eyes; this is a cataract. It usually happens when the protein in our lens moves or clumps together, affecting the clarity of our vision.

Types of Cataracts

There are three common types of cataracts you may possibly experience as you age.

  • Cortical.Cortical cataracts affect the clarity of outside of the lens. If you have cortical cataracts, your vision will become blurry or dimmed.
  • Posterior Subcapsular. The “halo” effect that some people experience, as well as the light and glare sensitivity is caused by this type of cataract.  Posterior Subcapsular cataracts happen when a cloudy area forms on the back surface of the lens.
  • Nuclear Sclerotic. This is the most common type of cataract and happens gradually over time.  It is identified by the hardening and yellowing of the lens.  The protein fibers in the lens clump together and cause the light coming through the eye to scatter instead of pass through clearly.  A filmy sensation in vision or diminished contrast may occur as a nuclear sclerotic cataract forms and worsens.


Symptoms of Cataracts

You may be wondering just exactly what to watch for if you suspect you have cataracts.  Here are some of the most common symptoms associated with cataracts:

  • Experiencing clouded, dimmed, or blurred vision
  • Seeing “halos” around lights
  • Double vision in one eye
  • Having frequent prescription changes
  • Noticing fading colors in your vision
  • Extra sensitivity to glare and light

Because cataracts worsen gradually, most people don’t really notice they have them until their vision has been significantly altered, affecting the functions of everyday life, like reading or driving – especially at night. If you notice your vision changing in the above mentioned ways, call or come in and let Dr. Smith take a look at your eyes to properly evaluate and diagnose the issue.  We want you seeing your clearest! 435.359.2020
