Cataract Causes: Understanding & Research | Sight Research UK

What Are Cataracts?

Cataracts develop when the lens inside your eye, which is typically clear, starts forming cloudy patches. Over time, these patches can grow, leading to blurry or misty vision and, in severe cases, blindness. It's akin to a clear glass becoming frosted, limiting our vision. Cataracts can appear in both eyes, though they might not develop simultaneously or to the same extent in each eye.

What Happens in Cataracts?

As we age, our eye's lens can undergo changes. Initially clear like glass, the lens can start to resemble frosted bathroom glass, restricting our vision. This clouding can impact daily activities, especially tasks like driving. While cataracts predominantly affect older adults, they can also be present in babies and young children.

What Causes Cataracts?

The exact reason for cataract development as we age remains somewhat elusive. However, several factors might increase the risk, including a family history of cataracts, smoking, diabetes, eye injuries, prolonged steroid use, and excessive alcohol consumption.

How Are Cataracts Diagnosed?

If you notice symptoms like blurred vision, increased sensitivity to light, or faded colours, it's advisable to see an optician. They will conduct various eye tests, including a visual acuity exam, to measure your vision at different distances. If cataracts are suspected, you may be referred to an eye specialist for further tests and potential treatment.

How Are Cataracts Treated?

In the early stages, stronger glasses and enhanced lighting might suffice. However, as cataracts progress, the only proven effective treatment is surgery. This involves removing and replacing the affected lens. It's a common and generally safe procedure that can restore vision.
