Eyelash curlers are a mainstay on lists of essential makeup tools. They do look a bit like medieval torture devices and can be rather tricky to use for the uninitiated, but it's a small price to pay for having eyes that, as they say, truly "pop."
Why not up the ante by bringing heat into the picture? Yes, heated eyelash curlers supposedly make your eyes pop just that much more. But we definitely question the wisdom of holding a heated tool 2 millimeters from your eyeball -- this is one tool you can surely do without.
