Cataracts: Understanding Early Signs


Has your vision been declining and you are wondering if you need a stronger pair of prescription eyeglasses? Weakening vision could be an early sign that a cataract is forming. While cataracts are a common eye issue affecting older adults, they can sometimes affect younger individuals. The good news? Cataracts can be effectively treated with a fairly routine surgery. Let’s explore the initial symptoms of cataracts and the crucial role optometrists play in their detection and management.

What are Cataracts?

Cataracts refer to the clouding of the eye’s natural lens, which affects vision clarity. This condition typically develops slowly and can occur in one or both eyes. While cataracts are often associated with aging, they can also result from factors like eye injury, genetics, prolonged exposure to UV light or certain medical conditions.

Types of Cataracts: There are several types of cataracts, including:

  • Age-related cataracts: Develop gradually over time and are the most common type.
  • Congenital cataracts: Present at birth or develop during childhood due to genetic factors or maternal infections during pregnancy.
  • Traumatic cataracts: Result from eye injuries or trauma to the eye.
  • Secondary cataracts: Develop as a result of other medical conditions or treatments, such as diabetes or prolonged use of corticosteroids.

Symptoms of Cataracts: At first, you may not notice that you have a cataract. But over time, cataracts can cause some of the following symptoms:

  • Blurred or cloudy vision
  • Increased sensitivity to glare, particularly in bright light
  • Difficulty seeing at night
  • Fading or yellowing of colors
  • Double vision in one eye

How Optometrists Can Help with Cataracts:

Optometrists play a crucial role in the detection, management, and referral of cataracts. Here’s how they contribute:

  • Detection and Diagnosis: Optometrists look for early signs of cataracts at every eye exam using their specialized tools.
  • Monitoring Progression: Cataracts are not necessarily surgically removed when they first appear. Optometrists may monitor changes in vision and cataract development over time, determining the appropriate timing for surgery for each individual.
  • Education and Counseling: Optometrists educate patients about cataracts, explain available treatment options, and provide counseling on lifestyle modifications.
  • Referral for Treatment: When necessary, an optometrist will make a referral to an ophthalmologist for surgical removal of the cataract. The surgery to remove cataracts might also reduce a patient’s dependency on eyeglasses after the operation.
  • Post-operative Care: Optometrists provide post-operative care, including follow-up appointments to monitor healing and visual recovery after cataract surgery.

See the Difference: Visit an Optometrist

If you or your loved ones experience any of these symptoms or haven’t had a dilated eye exam lately, it’s essential to schedule an appointment with an optometrist for a comprehensive eye exam. Optometrists are trained to detect cataracts and other eye conditions early, allowing for proactive management and treatment.
