The local Abrio method of birefringence assessment was applied for the first time to strengthened glasses, and it was used to investigate the micro-stress distribution in float glass subjected to ion-exchange strengthening. It is demonstrated that the thickness of the stressed layer can be determined with great precision, and a correlation is found between the depth of the stressed layer and the penetration depth of potassium cations in the course of ion exchange.
