What Is The Main Cause Of Cataract

Do you know what causes cataracts? Were you even aware that there's more than one type of cataract? Well, my dear readers, today we will delve into this topic together and explore the fascinating world of cataracts!

Cataract: The Basics

Let's start with the basics. Cataracts are a clouding of the natural lens in the eye that affects vision. They are a common condition, especially in older adults. But did you know that there are three different types of cataracts? That's right, we've got cortical, nuclear, and posterior subcapsular cataracts. Each type has a slightly different cause and appearance.

Cortical Cataracts

Cortical cataracts occur when the outer layer of the lens becomes cloudy. This type of cataract looks like spokes on a wheel, with the opacity moving in towards the center of the lens. As the cataract progresses, it can cause vision loss and glare.

Nuclear Cataracts

Nuclear cataracts occur in the center of the lens and are usually associated with aging. This type of cataract causes a yellowing of the lens and can lead to nearsightedness.

Posterior Subcapsular Cataracts

Posterior subcapsular cataracts occur at the back of the lens and can form more quickly than the other types. This type of cataract is associated with prescription steroid use and can cause difficulty seeing in bright light or a halo effect around lights.

The Cause of Cataracts

So, what causes cataracts? There are a number of factors that can contribute to the development of cataracts. Age, genetics, and smoking are all risk factors. Exposure to sunlight and UV rays can also be a factor, so don't forget to wear your sunglasses, even on cloudy days! Medical conditions such as diabetes and high blood pressure can also increase the risk of cataracts. And last but not least, certain medications such as steroids can cause cataracts to form more quickly.

Treatment for Cataracts

So, what do you do if you develop a cataract? Fortunately, cataracts can be treated with surgery. During cataract surgery, the cloudy lens is removed and replaced with an artificial lens. This surgery is usually very successful and has a high rate of patient satisfaction.
