Causes of vision loss due to cataracts - from aging to injury

Want to know why cataracts occur and what risk factors may contribute to this? We will explain the different causes of cataracts to better understand this common eye disease.

The Natural Process of Aging

Cataracts are often associated with age. Normally, the lens of the eye is transparent and flexible, allowing it to change shape as needed. However, as we age, the flexibility of the eye's lens decreases, which can lead to clouding.
“About 90 percent of all cases of cataracts are associated with age,” says general practitioner Elena Alexandrova especially for MedicForum.

Diabetes and other metabolic diseases

“Another cause of cataracts can be diabetes. Diabetes increases the sugar content of the eye fluid, which causes excess sugar to be deposited in the lens and make it cloudy.”
Other metabolic diseases, such as calcium deficiency or hyperactivity parathyroid gland, can also lead to cataracts.

Eye diseases and eye injuries

Cataracts can also be caused by other eye conditions, such as eye inflammation or severe nearsightedness. Eye injuries can also cause cataracts.

Heredity and infectious diseases

Genetic defects or infectious diseases during pregnancy can lead to the birth of a child with cataracts.

Rare causes

“In rare cases, cataracts can be caused by defects in lens metabolism, poor diet, heavy smoking, radiation and ultraviolet radiation (UV light),” explains Alexandrova.

Symptoms and diagnosis

Diagnosis of cataracts requires a detailed examination by an ophthalmologist.
“Symptoms may include blurred vision and increased sensitivity to light.”
It is important that relatives know the symptoms of cataracts and can interpret them correctly, since those affected often misjudge or ignore vision impairment.
Many people worry about developing cataracts as they age. But did you know that there are things you can do to protect your eyes and reduce your risk of disease?

Protect your eyes: preventing cataracts

Many people do not realize that cataracts, one of the most common causes of vision loss, can in some cases be prevented. In this article, you will find useful information and practical tips to help keep your eyes healthy.

Wear safety glasses

One of the most important ways to prevent cataracts is to protect your eyes.
“You should always wear safety glasses when performing manual tasks that may injure your eyes, such as sanding or drilling. UV protection is equally important,” says the doctor.
Good sunglasses will protect your eyes when you are in the sun. You should also wear safety glasses in the tanning salon.

Regular examinations

Another important preventive measure is regular examinations by an ophthalmologist.
“Starting at the age of 40, you should have your eyes checked every 12-24 months. Regular eye tests can detect cataracts at an early stage, even if the symptoms are barely noticeable,” advises doctor Aleksandrova.
