Abstract
Contact lens discomfort (CLD) is a sporadic or frequent condition that affects millions of contact lens users worldwide. The experience of the contact lenses (CLs) wearers is strongly influenced by many factors, among these the physical properties of lens materials. Especially, the friction coefficient (CoF) plays a critical role in the balance between lenses and ocular environment. The aim of our study is to quantify the CoF for different CLs by means of a nano-tribometer. Three experiments were performed following protocols already published in the literature, in order to evaluate the CoF dependance on testing parameters, such as sliding speed, applied normal force and number of sliding cycles. Our results identify a lack in the reproducibility of already published experiments and the necessity to identify a measuring standardized protocol.
