Cataracts are caused by a variety of factors. There are numerous reasons of Cataract and why a person may develop them. We’ve included some of the most common factors in this post, along with a quick explanation. Learn about them so you can recognise and delay the progression of Cataract in your eye lens, if not completely avoid it.

What is a Cataract?

A cataract is a hazy patch that forms in the eye’s lens. These spots usually grow larger over time, causing impaired, cloudy vision and, in extreme cases, blindness.

When we’re young, our lenses are usually clear like glass, allowing us to see perfectly through them. As we become older, they get frosted and blurry, like foggy bathroom glass or a fogged-up window, and they begin to impair our eyesight.

Cataracts usually attack both eyes at the same time. They might not emerge in each eye at the same time or in the same way. They’re more common in elderly individuals, and they can make it difficult to do things like drive, read, watch television, or stare up in the distance. Cataracts can also damage the eyes of children and newborns.

Symptoms of Cataract 

In either one or both eyes, a person with a cataract may begin to feel the following symptoms:


  • 1. The vision that is hazy or dull
  • 2. Sensitivity to light or glare
  • 3. Blindness at Nigh
  • 4. double vision
  • 5. Changes in Eyepower are frequent
  • 6. Colours fading or yellowing
  • 7. More light is required for daily tasks
  • 8. Light has halo effects.

There may be a small development of the foggy patch at the beginning of the growth of a cataract in your eye lens, and you may be unaware of any vision alterations. The cataract will grow larger over time, and the hazy white patch will cover most of your lens, causing vision loss and distortion of light travelling through the lens. The symptoms may be more obvious at this point. 

Causes of Cataract 

There are a lot of reasons of Cataract development in a person’s eye. The lens in your eyes works similarly to the lens of a camera. Both of these techniques allow us to see things up close and far away simply shifting the focus of our eyes.

Water and proteins are the two main components that make up the majority of your eye. Proteins remain in your eye as they gradually break down and disintegrate. These residual proteins might cause your lenses to fog up, making your vision hazy.

Factors that may be linked to the development of cataracts have been uncovered by researchers and health care experts from all over the world. Apart from growing older, there are a number of following factors that can hasten the beginning of cataracts:

Diabetes: High blood sugar damages blood vessels all over the body if left untreated. The blood vessels in the eyes, which are very small, are included in this. The development of cataracts and other eye diseases is more likely when these blood vessels are damaged by diabetes.

Drug, steroid, and medications side effects: According to scientists, several chemicals and pharmaceuticals have been discovered to cause lens opacities and cataracts. Other medications have been found to accelerate the progression of pre-existing lens opacities. 

While we can’t completely avoid it, people who take steroid medicines on a regular basis can take precautions by consulting an eye expert to reduce their chances of developing cataracts.

Eye surgery or infection: If you’ve had eye surgery before, your eyes may be more sensitive and susceptible to infection. This may result in the formation of a cataract in your eye lens.

Ultraviolet Radiation: When you don’t wear eye protection or sunscreen in the sun, you’re exposing your eyes to a lot of UV radiation. To avoid UV damage and stress to your eye lens, always use UV-protective sunglasses and sunscreen.

Obesity: The cloudiness could be the result of inadequate nutrition or high blood sugar levels, both of which are common in obese people.

Smoking: In addition to cataracts, there are many other ailments that can develop inside your body if you smoke on a daily basis. A cigarette contains more than 4,000 harmful compounds that can harm your general health, including your eyesight.

Excessive alcohol: use has been related to an increased risk of eye cell damage, making them susceptible to cataract formation.

Family History: If you have close ancestors who have had cataracts, your chances of developing them are higher than if you don’t.

What is the Treatment for Cataract?

If you catch your cataract early enough, your doctor may be able to offer you a new prescription for your glasses to help you cope for a period. However, if your vision is interfering with your everyday activities, cataract surgery may be required.

Cataract surgery is safe and effective with a quick recovery process. The surgical excision of a cataract, according to the National Eye Institute, is a relatively routine procedure that is exceedingly effective around 90% of the time.

It is essential that you have the operation as soon as you are aware of the problem in order to avoid any potential blindness complications. So, rather than waiting for your cloudiness to worsen, have your eyesight restored now with advanced, safe, and rapid cataract surgery performed by your health care professional and look out for any reasons of Cataract.
