You cannot wear colored contact lenses over your regular contact lenses. The colored contact lenses you want to wear are even not wearable because the lenses stick to your eyes like suction cup, so the colored lenses cannot stay.
Supposed that you wear two pair of contact lenses at the same time, you can hardly blink your eyes. The circumference of the contact lenses will also cut the insides of your eyelids.
Above all, if you do this, you will definitely hurt your eyes. If you want to look good, you can consult your doctor or optician to get colored prescript contact lenses.
Don’t do that, because contact lenses are not meant to be worn that way and it could be harmful to your eyes.
However, not sure why you would want to do that, but if it is because you would like to change your eye color and be able to see at the same time, then you can just buy prescription color contacts.
Prescription color contacts such as Freshlook and Air Optix, are contacts that change your eye color that you can order in your prescription so you can see. This is just 1 lens on your eye but you can see and have a new eye color at the same time!
No need to risk your eye health by doubling up on lenses.
