Please ensure that the lenses are not inside-out, as this is one of the most common causes of movement on the eye.
If the lenses are inverted, simply flip them inside-out and give them a good wash before reapplying.
Ensure that your lenses are the correct prescription and fit your eyes properly. Lenses that are too loose or tight can move around on the eye. Consult your eye care professional if you suspect the fit might be the issue.
