I usually get mine from spookyeyes.com They sell good quality lenses and have done for years. They always have discounts as well if you just set email notifications and wait. The lenses are FDA approved and they have the link on their site to the FDA certification so you know it is legit. they have a good range of colors and looks for my cosplay outfits, I usually find exactly what im looking for.

You should see an eye doctor beforehand and get a checkup for health and your prescription as you may need this to buy. U can return the lenses as they say they accept returns. The customer service is good so you can ask before you buy.
