Eye Wash. A firstaid product everyone should have in their home. You have probably not thought of it before, but without the eye wash you can lose sight, if accidents occur! If you get chemicals or foreign bodies in the eye, the severity of the injury is greatly depending on how quickly you get your eye flushed effectively. This is particularly true of corrosive chemicals such as strong acids and bases. The advantage of irrigating with eye wash compared to rinsing with water is, first, that it is sterile, but also to the ergonomic eye cup which makes it easier to rinse the eye thoroughly.
