Series 6
Series 6 is inspired by a vector field in the thesis Mathemathical model of the human eye growth and the development of myopia (near-sightedness) by Alexander Sas at the University of Antwerp (Master of Physics). The x-axis is related to the diameter of the eye. The y-axis expresses how strong the lens is.
In case both parameters are equal, the eye has a good sight, hence the diagonal is empty. In case both are not equal, the vector field shows how the eye can grow to improve its sight. The further away from the diagonal, the stronger the required correction, which is emphasized by the darker colors.
