uniform structure of a metric space

Let $(X,d)$ be a metric space. There is a natural uniform structure on $X$ , which induces the same topology as the metric. We define a subset $V$ of the Cartesian product $X\times X$ to be an entourage if and only if it contains a subset of the form

V_{\varepsilon}=\{(x,y)\in X\times X:d(x,y)<\varepsilon\}

for some $\varepsilon$ .
