Cataracts are one of the most common causes of vision changes as we age. They occur when the eye’s natural lens — the crystalline lens — becomes progressively cloudy. Though cataracts develop slowly, they can cause subtle yet noticeable changes in your vision. Recognizing the early symptoms helps ensure timely care and proper follow-up.
1. Blurry or hazy vision
The most common early sign is a gradual loss of visual sharpness. Everything may seem slightly foggy, as though looking through a steamed-up window.
2. Increased sensitivity to light
People often notice discomfort in bright environments or more pronounced glare, particularly while driving at night or in sunlight.
3. Reduced night vision
Cataracts make it harder to see clearly in low-light settings. Night driving may become more challenging or feel unsafe.
4. Halos around lights
Halos or glowing rings around headlights, streetlights, or screens are a typical symptom and can be especially bothersome at night.
5. Changes in color perception
Colors may appear duller, less vibrant, or slightly yellowed. This shift usually happens gradually over time.
6. Double vision in one eye
A cataract can cause monocular double vision — seeing a double image with just one eye.
7. Frequent prescription changes
If your vision seems to worsen despite frequent updates to your glasses prescription, cataracts may be the cause.
When should you seek care?
If you notice any of these symptoms, especially if they progress, it’s a good idea to schedule an eye exam. Cataracts are very common and highly treatable, especially with surgery when vision becomes significantly impacted. A comprehensive eye exam will confirm the diagnosis and help determine the right moment for intervention.
