I don’t know of any sites off the top of my head but I’d stick with any reputable ones, check reviews if they have them, As with any decorative contact lenses however it’s best to see your optician before you use them. 

the most honest looking site I found was blindcontactlenses.co.uk, though their other site with a .net address is no longer in service which is a little sketchy imo. 

Thanks for the advice!

If anyone else knows a safe retailer of blackout contacts, please let me know!
