So, I bought some coloured contact lenses (purely for dress up, nothing to do with vision) about 4 years ago. They have been kept in their little containers in the eye drop solution all this time and I have only ever worn them once when I first got them. I found them again and was wondering if they are still safe to put in? They do not look worn out or anything. If they are not still good, why not? Thank you
