If you have dark colored eyes you might wonder if there are any colored contacts that will work for you.
The good news is that there are certain types, styles and colors that work just fine for darker colored eyes but some colors and tints should be avoided because they will either not work at all, or not do enough to really be noticed, or worth it.
The best colored contacts for darker eyes are the solid colors, usually used for costumes, halloween and theatrical type events.

The tinted colors that will work for lighter colored eyes will have virtually no effect on someone with dark colored eyes.
Notice I don’t just say “brown”, because there are many shades of brown, with some being very light, while other shades of brown and possibly the most common is dark brown, or “puppy dog eyes” that might be called.
This site is about purple contacts, which are absolutely perfect for people with dark eyes who might have been considered colored contacts would be useless to them.
So yes, if you have dark eyes, you can find colors that work for you but your selection is more limited.
Purple contact lenses are almost always used and made for costume and theatrical purposes so you should have no problem getting some that work perfectly for your shade.
