Hazy vision

Like looking through a window nobody has cleaned in years.

Typical visionWith hazy vision
Moderate: a haze and a yellow-brown tint drain contrast from the scene.

When is the eye appointment, and how many tablets go in each dose?

What's happening

Hazy vision happens when the clear parts at the front of the eye, the lens or the cornea, turn cloudy. Light scatters instead of focusing, so everything loses contrast and sharpness, and colours drift toward yellow and brown. Its most common cause, cataract, is also one of the most successfully treated conditions in medicine.

This simulation is for understanding and empathy. It is not a diagnosis and doesn't replace an eye examination.

What you might notice

Low contrast

Grey on grey disappears, and steps and kerbs flatten out.

Yellowed colours

Whites look cream and blues look dull.

Glasses stop helping

Prescriptions change often and help less each time.

Needing more light

Reading needs a much brighter lamp than it used to.

Where it gets hard

  • Reading, especially small or low-contrast print.
  • Night driving.
  • Recognising faces at a distance.
  • Trips and falls on steps with no contrast edge.

Often caused by

Conditions commonly linked to this pattern.

  • Cataract
  • Fuchs corneal dystrophy
  • Corneal scarring or infection
  • Clouding after cataract surgery (posterior capsule opacification)
  • Uveitis
  • Severe dry eye

Treatment and support

Cataract surgery replaces the cloudy lens with a clear artificial one and is among the most common operations in the world. If clouding returns afterwards, a quick laser treatment clears it. Corneal causes may be treated with drops or a corneal transplant.

Get checked the same day if

Haze comes on suddenly, especially with pain, a red eye, sensitivity to light or halos around lights.

If it's sudden or comes with other symptoms, go to an emergency department.
