In weak lensing we show that there are three regimes, depending on the value of $\\bar {\\lambda}=1/\\omega d^{2}$, where $\\omega $ is the Ho\\v{r}ava-Lifshitz parameter and $d$ characterizes the lensing geometry. When $\\bar {\\lambda}$ is close to zero, light deflection typically produces two images, as in Schwarzschild lensing. For very large $\\bar {\\lambda}$ the space-time approaches flatness, therefore there is only one undeflected image.
