Abstract
The present disclosure discloses an optical lens module and a virtual reality device. The optical lens module includes: a lens assembly, and transflective layers attached to surfaces on a light incident side and a light emitting side of the lens assembly. The lens assembly includes a central region and at least one annular region surrounding the central region. The central region has a refractive index smaller than the at least one annular region. When more than one annular region is provided, the annular regions are sequentially arranged layer by layer, the annular region located on the outermost side has the maximum refractive index, and for any other annular region, the refractive index is smaller than that of the annular region located outside thereof.
