Possible connections between the inhomogeneities responsible for the Lyman-α forest in quasar spectra and gravitational lensing effects are investigated. For most models of the Lyman-α forest, no significant lensing is expected. For some versions of the CDM model-based minihalo hypothesis, gravitational lensings on scales ≲0″.1. would occur with a frequency approaching that with which ordinary galaxies cause arcsecond scale lensing.
