Definition: Corneal haze describes a cloudy or opaque appearance of the cornea. The cornea is the clear front window of the eye. It is the part of the eye that transmits and focuses light into the eye. The cornea is a fairly complex structure that has five layers. If this part of your eye becomes damaged through disease, infection, or injury, scarring can interfere with your vision by blocking or distorting light as it enters the eye. The cornea is normally clear, so corneal haze can greatly impair your vision.
