If you would love to make your eyes look red for a long time, you can consider using makeup. With the right tricks, it's possible to use aesthetic tricks to make your eyes appear red and puffy as if you've just been crying, even if you feel perfectly fine. Because these tricks don't actually irritate your eyes, they're vastly more comfortable than some of the methods. Firstly, apply small dots of red eyeliner around the outline of your eye. You can also use a red eye shadow or red lip liner, but make sure that any lip liner you use is mild enough to use near your eyes before applying it. Place the dots along the entire bottom lid. For an even stronger red effect, you can also apply the dots along the upper lid. Secondly, smudge the liner over your skin using a cotton swab or makeup smudge stick. In order to make your eyes look red, you will need to cast a somewhat muted red "shadow" around their lids. None of the original lines or dots should be visible, so continue smudging until you can no longer see the original dots.
