According to Dr. Roman-Lantzy, Cortical Visual Impairment (CVI) âis the leading cause of visual impairment in children today.â CVI differs from other types of visual impairment which are due to physical problems with the eyes. CVI is a neurological disorder caused by damage to the visual centers of the brain, which interferes with communication between the brain and the eyes. The eyes are able to see, but the brain is not interpreting what is being seen.

When Earl S. Tupper invented Poly-T, a new and better form of plastic, he opened the door for plastic to become a key material in household products. His Tupperware line, with its newly invented stay-fresh lid, also proved that goods made out of plastic could be useful, and attractive and lightweight.In addition, Tupper's company had a big impact on how household products and other items, especially for women, were sold.arl Tupper sold Tupperware to the Rexall Corporation in 1958. Rexall changed its name to Dart Industries, which merged with Kraft Industries to become Dart and Kraft a decade later. In 1986, Dart and Kraft split and Tupperware became part of one of the new companies, Premark International.
