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.
Clumping in the vitreous humor is the most common cause of floaters, and it generally occurs with aging. Inflammation in the back of the eye, posterior uveitis, can be caused by an infection or an inflammatory disease, and it results in floaters. Bleeding or vitreous hemorrhaging is more serious, and it can be the result of an injury; one of the symptoms is the appearance of floaters.
