    Abstract: An eyeglass support is adapted for pinch-holding the eyeglass (5) between three first contact portions (41-43) and three second contact portions (61-63). The first contact portions form a height reference for positioning the eyeglass whereas the second contact portions ensure application of the eyeglass against the first contact portions while conforming to any possible shape for the eyeglass. The support suits for being incorporated in a reflection measurement apparatus. In particular, it is useful for measuring reflection of eyeglasses provided with antireflecting coatings or for rating a protection against UV hazards which is provided by an eyeglass to a wearer of said eyeglass.
