The lenses come in a lense fluid that are akin to eyedrops. You can put them on straight from the box. Be sure to not spill the fluid, cause in case you can't get them in your eye at first try and they start to dry out, you can dip the lenses in the fluid again. If you need more than that, you can use regular eyedrops. You only need the cleaning solution if you want to wear them again the next day.
