Let $R$ be a commutative ring with unity. The essential ideal graph $\mathcal{E}_{R}$ of $R$ is a graph whose set of vertex consists of all nonzero proper ideals of R. Two vertices $\hat{I}$ and $\hat{J}$ are adjacent if and only if $\hat{I}+ \hat{J}$ is an essential ideal. In this paper, we characterize the graph $\mathcal{E}_{R}$ as having a finite metric dimension. Furthermore, we identify that the essential ideal graph and the annihilating ideal graph of the ring $\mathbb{Z}_{n}$ are isomorphic whenever $n$ is a product of distinct primes. In addition, we estimate the metric dimension of the essential ideal graph of the ring $\mathbb{Z}_{n}$. Moreover, we determine the topological indices, namely the first and second Zagreb indices, of $\mathcal{E}_{\mathbb Z_n}$.
