        <p>The primary use of topological indices (TIs) in chemical sciences lies in estimating the physical and chemical attributes of molecular graphs. The refractive, reflective, and transmission properties of glass has made it suitable for the production of optical lenses, prisms, and optical electronic materials and have wide applications in the optical industry. In this article, first, Revan indices are obtained using M-polynomial, and their relationships are proved. Afterwards, utilizing these relationships, Revan indices for the molecular structure, Para-line structure, and Subdivision structure of Glass are computed. In conclusion, utilizing MATLAB programming, we can demonstrate that the presence of an M-polynomial (M-P) enables the computation of various Revan indices for any molecular graph.</p>
