Cataracts are a common eye condition that affects people and animals. A cataract is a clouding of the eye lens, causing vision loss and eventually leading to blindness if left untreated. Cataracts are most common in older people but can occur at any age and may be present at birth.

Symptoms of cataracts in people include cloudy or blurry vision, difficulty seeing at night, and sensitivity to light and glare. Patients report seeing halos around lights and changes in how colors appear. If you experience any of these symptoms, it is essential to have an eye examination to determine the cause.

So, what causes cataracts? How common are they? How are they treated in the early stages? Read on to learn more.

What Causes Cataracts?

Cataracts are a common age-related eye condition that occurs when the eye's lens becomes cloudy or opaque. This cloudiness obstructs light from passing through the lens, causing vision problems. Several factors can contribute to the development of cataracts, including:

 

• Aging

Cataracts are most commonly associated with aging. As we age, the proteins in the eye's lens can break down and clump together, leading to cloudiness.

 

• Sun Exposure

Prolonged exposure to UV radiation can damage the lens's proteins, leading to cataracts.

 

• Diabetes

People with diabetes are more likely to develop cataracts than those without the condition.

 

• Certain Medications

Some medications, such as steroids, can increase the risk of developing cataracts.

 

• Trauma

An injury, such as a blow to the head or eye, can cause cataracts.

 

• Inherited Factors

Some people may be more prone to developing cataracts due to inherited genetic factors.

How Common Are Cataracts?

Cataracts are quite common, especially as people get older. According to the World Health Organization (WHO), cataracts are the leading cause of blindness globally. They account for approximately 50 percent of all cases of blindness. It is estimated that around 20 million people are blind due to cataracts, and roughly half of all cases of blindness due to cataracts occur in people over the age of 50. 

Cataracts are more common in some populations than others, and they are more likely to occur in people who have certain risk factors, such as diabetes, prolonged exposure to UV radiation, and a history of smoking.

What Is the Treatment Process of Early Cataract Treatment?

It is important to note that cataracts cannot be prevented. You can reduce your risk of developing them by wearing sunglasses or a hat to protect your eyes from UV radiation, not smoking, and controlling conditions such as diabetes.
 

Eyeglasses and Vision Aids

In the early stages of cataracts, treatment may not be necessary. It is because the cloudiness in the lens may not be severe enough to affect vision significantly. In these cases, your doctor may recommend that you monitor your vision and update your eyeglass or contact lens prescription as needed.

Medication

In some cases, a medication or eye drops may be used to help delay the progression of cataracts or to improve vision. However, these treatments are not always effective and are typically not used as the primary treatment for cataracts.
