Like all black ones? For Halloween
also amethyst ones? For, everyday.

thank you.

$100-$200 for the good ones
anything under that price you should not ever buy for crazy lenses because they are cheap and may not be sized right so they can cut your eyes.

It totally depends.. u can get less expensive ones for about $80/pair, or over $400 if u want some really cool & detailed hand painted ones.

l am not sure if u mean u want lenses that r just plain black, or if u want the ones that r black & cover ur whole eye. The ones that cover ur whole eye r called ''scleral'' lenses, & r more expensive.

Be sure u order them from a reputable store & that they r the FDA approved lenses. There r lots of cheap knock-off ones out there & they can damage ur eyes.

Here are some contacts that you might be interested in. Make sure you see a doctor before wearing any kind of contacts.
