Crazing is the phenomenon that produces a network of fine cracks on the surface of a material, for example in a glaze layer. Crazing frequently precedes fracture in some glassy thermoplastic polymers.razing occurs in some thermoplastics such as acrylonitrile butadiene styrene (ABS plastic) when stressed. It is a typical response in rubber toughening, where crazes are initiated at the surfaces of the rubber particles added to toughen the material.
An enlarging pterygium, however, may cause redness and inflammation. In some cases, a pterygium can grow onto the centre of the cornea (the clear, outer layer of the eye covering the iris and pupil) and interfere with vision. It may also distort the shape of the cornea, causing a condition called astigmatism. The result can be blurred vision.
