If your eyes hurt when you wear colored contact lens, check if you have put them on the wrong side.

You have put beautiful hazel contacts but if you experience red eyes and pain, take off the contacts immediately and check if you have worn them on the right side. The part that touches your eyes has the edge slightly tilted inside, and if the colored contacts you bought have a dark color, they will have a bit different color.

Put the contact lens on your finger and observe. The side that is tilted inside is the part that touches your eyes and the side that has its edge tilted to the outside should not touch your eyes. After that, using the cleansing liquid, clean your hazel contacts before wearing the contacts.

The furs of cat and dog, and dusts will cause pain so you must take extra careful for them.
