Cloudy Vision in One Eye: What Does It Mean?

Quick answer: Cloudy vision in just one eye is most often an early cataract (they develop at different rates in each eye), and it usually isn't an emergency, though it does need an eye exam. Less common causes include an eye infection, migraine aura, or a refractive error. Sudden cloudiness with stroke-like symptoms is a medical emergency.

Cataracts: the most common cause

Cataracts eventually affect nearly everyone, and because they progress at different rates in each eye, you may notice cloudiness in one before the other. Other cataract signs include faded or yellowing colors, halos around lights, poor night vision, and a frequently changing prescription. Cataracts develop slowly and are monitored until it's time for cataract surgery.

Other possible causes

• Eye infection: often with pain, redness, discharge, or crusting, see eye infection care.
• Migraine aura: temporary cloudiness, zig-zags, or sparkles before a migraine.
• Refractive errors: myopia, hyperopia, astigmatism, or presbyopia.

When cloudy vision is an emergency

A sudden onset of cloudy vision in one eye, especially with a severe headache, reduced consciousness, numbness or tingling, slurred speech, facial drooping, or after head trauma, can signal a stroke or other serious event. Go to the nearest ER or call 911 immediately.
