Eyes are very susceptible to hormonal changes so pretty much any hormonal contraceptives are likely to have an impact on your eyes. Have you tried a tri-phasic pill such as Qlaira? It's designed to more closely mimic the natural hormones in your body more so than other pills so it might have less of an impact. I changed pill recently and noticed my eyes getting worse straight away. I'm going to get a script for Qlaira next month and cross my fingers it won't dry my eyes as much.
