The Draize test has become virtually obsolete due to the development of a synthetic cellular tissue that closely favors human skin. Researchers can test the likely harm a product can do to skin by using this artificial skin instead of testing on animals. Another substitute for this test is a product called Eyetex. This synthetic material becomes opaque when a product damages it, closely aiding the way a real eye acts towards harmful substances. Technologies such as computers have been used to evaluate and calculate the potential harm that a product or chemical can cause, and human tissues and cells have been used to analyze the effects of harmful products. All of these experiments have proven to be useful and reliable substitutes for substance testing on live animals. Therefore, the testing of potentially deadly substances is inexplicable
