Abstract	Objective: Determine the relationship that exists between visual impairments and the perception of color for dental restorations under natural and artificial light conditions. Material and methods: A total of 38 third and fourth year students of the Universidad Tecnologica de Mexico participated in this research. They all signed informed consent as to the release of the data concerning their visual conditions. A certified ophthalmologist examined them for visual acuity, retinal disease, refraction and color test using Ishihara test strips. Each participant was given a shade guide with Vita classic shades A1-A4, B1-B4, C1-C4, and D2-D4. The assessment was made under natural and artificial light sources. This is a transversal, observational, analytical, and prospective research made through a non probabilistic consecutive sampling. The statistical analysis used were χ2 with a level of significance of p < 0.05. Results: A total of 9 (0.23%) individuals had no visual impairment, 16 (0.42%) were diagnosed as having hypermetropic astigmatism and hypermetropia, 2 (0.23%) had color perception problems. The discriminative ability was better using natural Yeni Arreortua Cisneros,* Gerardo De Leo Vargas, Manuel Salgado Valladares,* Erdson R Ocadiz Ibarra,** Gustavo Olvera Alvarez,* Rosa Maria Diaz Romero****** * Cirujano Dentista egresado de la Universidad Tecnologica de Mexico.
