Yep.I`m the same.Tried different contact lenses...still seem as if i`m on a permanent lsd trip.Last time I went to my optician I told him and said
"Look..if you`re going to have to fit lenses which are like marbles don`t bother...I`ll gouge my eyes out instead." Had to pick him up off the floor.
Reminded me of Billy Connelly`s rendition of a man in a Reliant Robin car...with Prescription Windscreen!!! How funny would THAT be? But sure...it is annoying in all serousness but I wonder about drug side effects.We tend to blame the illness but folk bring me back to thinking about the cocktail of drugs we folk are on.Our brain receptors must wonder whether they are coming or going.
Interesting question.Will stick with the replies in the hope some bright spark comes up with a cause.
Best of luck.
