Symptoms and Types of Cataracts

All About Cataracts

Aging is inevitable, as are many of the body changes that come with it. Many people will develop cataracts as they age, which can alter visual acuity. Different in everyone, there are several types of cataracts and a variety of symptoms that can signal to you and your physician you may need corrective lenses or surgery.

What is a Cataract?

Cataracts are simply the result of a cloudy lens. The lens is a clear structure that focuses light onto the retina. It’s largely made of proteins which, as you age, can coalesce.  As the lens thickens and darkens, it can impair vision.  If the cataract grows large enough or situated in a certain area, It reduces the amount of light that reaches the retina thus causing a decrease in vision.  Surgery is the best option to correct this problem.

Types of Cataracts

The three main types of cataracts are:

  • Nuclear Cataracts — Cataracts found in the center of the lens are called nuclear cataracts. These typically lead to nearsightedness, possibly boosting your ability to read small print. However, over time your vision will yellow and cloudiness will increase, making night vision difficult. 
  • Cortical Cataracts — Cortical cataracts are white-colored obstructions found along the outer edges of the lens. Eventually, this type of cataract spreads inward, increasing the disruption of light focused on the retina. Cortical cataracts are most often associated with symptoms such as glare.   
  • Subcapsular Cataracts — This type of cataract has symptoms such as decreased vision in bright light or reading ability as well as halos and glares in low-light conditions. It is found at the back of the lens, and is often noticed more quickly than other types of cataracts, as it is in a direct line to the retina. 

Signs and Symptoms of Cataracts

How do you know whether or not you have a cataract? Only an examination from a trained physician can tell you for sure. However, if you are experiencing changes in your vision that include blurriness, yellowed tint around the edges of your visual field, light halos, impaired night vision or increasingly cloudy sight it might indicate a cataract.
