Symptoms and Diagnosing Cataracts

Cataracts are a common eye condition in which the lens of the eye becomes cloudy, resulting in blurred vision. The condition typically develops gradually and may affect one or both eyes. In this article, we will discuss the symptoms of cataracts and how they are diagnosed.

Symptoms of Cataracts

The symptoms of cataracts can vary depending on the type of cataract and how advanced it is. Some common symptoms include:

  1. Blurred or hazy vision: This is often the first symptom of cataracts. As the lens becomes cloudier, vision becomes increasingly blurred or hazy, making it difficult to see clearly.
  2. Sensitivity to light: People with cataracts may become more sensitive to bright light, which can cause glare or halos around lights.
  3. Difficulty seeing at night: Cataracts can make it difficult to see in low light conditions, such as driving at night.
  4. Changes in color vision: Some people with cataracts may notice that colors appear less vivid or have a yellowish or brownish tint.
  5. Double vision: This can occur in one eye or both eyes and can sometimes be corrected by closing one eye.

Diagnosing Cataracts

Cataracts are usually diagnosed during a comprehensive eye exam. During the exam, your eye doctor will perform a series of tests to determine if you have cataracts and how severe they are.

  1. Visual acuity test: This measures how well you can see at different distances.
  2. Dilated eye exam: During this exam, your eye doctor will use eye drops to dilate your pupils, allowing them to see the back of your eye more clearly.
  3. Slit-lamp exam: This exam uses a special microscope to examine the front of your eye, including the lens.
  4. Tonometry: This test measures the pressure inside your eye.

If your eye doctor determines that you have cataracts, they may refer you to a specialist for further evaluation and treatment.

In summary, cataracts are a common eye condition that can cause blurry vision, sensitivity to light, difficulty seeing at night, changes in color vision, and double vision. They are typically diagnosed during a comprehensive eye exam that includes visual acuity testing, a dilated eye exam, a slit-lamp exam, and tonometry. If you suspect that you have cataracts, it is important to schedule an appointment with your eye doctor to receive an accurate diagnosis and appropriate treatment.
