Two horse lenses suspended on water by cling wrap with four approximately parallel lasers directed through them. The 1 cm spaced grid indicates a near focus focal length of around 6 cm. Accommodation is the process by which the vertebrate eye changes optical power to maintain a clear image or focus on an object as its
