Cataracts

What happens in the eye with cataracts?

In cataracts, the eye’s lens becomes cloudy, which prevents light from passing clearly through the eye, causing vision to appear blurred or dim. The condition is most common with increasing age, but it can also be influenced by several other factors. For example, conditions such as diabetes, smoking, long-term use of certain medications, and previous eye injuries can increase the risk. Genetics may also play a role.

Common symptoms of cataracts

Symptoms usually develop gradually and may vary from person to person. Common signs include:

• Blurred or cloudy vision
• Increased sensitivity to bright light
• Glare from lamps or headlights
• Difficulty seeing in the dark
• Colors appearing faded or more yellow
• Light phenomena such as rings (halos) around lights
• Needing to change glasses more often
• Difficulty reading without strong lighting

It is common for symptoms to first be noticed in specific situations, such as driving at night or reading in dim light.

What do cataracts feel like?

Cataracts are not painful. Most people instead experience a gradual decline in vision. Many describe it as the world becoming less sharp, less clear, and sometimes slightly yellowish. Because the change happens slowly, it is common to adapt to the symptoms and assume it is simply due to aging or a need for new glasses.

When should you seek help?

You should have your vision checked if you notice that:

• Your vision worsens despite new glasses
• You experience more glare than before
• You avoid driving at night
• It becomes harder to read or use screens
• Colors no longer appear as clear

Sudden vision loss, eye pain, or severe light sensitivity should always be assessed promptly, as they may be caused by other eye conditions.

What can you do yourself?

You cannot completely prevent cataracts, but there are several ways to make daily life easier and take care of your eye health. Using good lighting when reading can help you see more clearly, and sunglasses with UV protection help protect your eyes in bright light. Avoiding smoking is also an important factor, as well as having regular eye exams to detect changes early. If symptoms become severe enough to affect your daily life, effective treatment is available in the form of surgery.
