The Draize Eye Irritancy Test is one of the tests used in cosmetic and production experimentation. The test is used to measure the harmfulness of chemicals found in household products and cosmetics by observing the damage they cause to animal s eyes and skin. Their eyes are held open with metal clips. The test lasts at least seven minutes causing the animals to suffer extreme pain, mutilation, and blindness. In other tests animals have tubes forced into their veins or throats and are pumped with toxic chemicals to measure the effect.
Animals can feel.
After all, humans are animals and we can feel pain when we get soap in our eyes or cut ourselves.
