[Cataracts] What causes cataracts that make your vision blurry?!

Your vision becomes dim and blurry with cataracts! It's an inconvenient eye condition that affects both near and far vision.

Presbyopia and cataracts are both diseases caused by aging,

but did you know there are differences in their causes and symptoms?

Cataracts are a condition where the transparent and clear lens becomes cloudy, leading to reduced vision,

making it an eye disease where both near and far distances are difficult to see.

Symptoms of cataracts include a feeling of fogginess and discomfort, as if looking through a constant mist.

In particular, vision may worsen during bright daylight hours.

1. Causes of Cataracts

Left: Normal eye / Right: Cataract eye

The most common cause of cataracts is aging. As people age, the lens becomes cloudy and opaque,

leading to reduced vision.

In addition to aging, there are various other causes such as diabetes, atopic diseases, long-term steroid treatment, UV exposure, and eye trauma.

Due to these reasons, light entering through the lens scatters, failing to focus precisely on the retina,

resulting in the blurry vision characteristic of cataracts.

2. Symptoms of Cataracts

Cataracts occur when the lens becomes cloudy.

Symptoms include difficulty seeing both near and far objects, and blurry vision.

Cataracts progress slowly, so symptoms are often not noticed in the early stages, but

it is crucial to be careful, as surgery can become difficult if the treatment window is missed.

3. Cataract Self-Diagnosis

Cataracts are characterized by vision that is blurrier than usual, and difficulty seeing objects both near and far.

Based on this, let's look at several self-diagnosis criteria for cataracts.

- Vision appears blurrier in bright sunlight, and it's hard to keep your eyes open.

- It's difficult to identify people or objects far away.

- When looking at books or objects at close range, vision appears blurrier.

- It has become harder to distinguish colors.

- Objects appear overlapped or double even when looking with one eye.

- You used to wear reading glasses, or suddenly you can see well without them.

If even one of these applies to you, it's advisable to suspect cataracts.
