ShinobiXikyu covered basically everything ever that could be said about this topic so i'll just throw in that honeycolor
is also good and does offer prescription lenses. (i've found that most, or at least a significant percentage, of circle lenses come in prescription strengths. i've never had issues finding what i need, and i have a pretty strong prescription!)
pinkyparadise's blue/aqua lenses are here
, and honeycolor's blue/aqua lenses are here
but again they're also mainly circle lenses, so (as mentioned above) if you'd rather have a regular-size lens or if your base curve doesn't work with circle lenses, then ordering through your eye doctor if possible would be the way to go!
also just a friendly tip about base curves, circle lenses, and contact prescriptions: i have an 8.4 base curve and circle lenses with an 8.6 curve fit SUPER comfortably on me. my sister has the same base curve as me and 8.6 circle lenses are unbearably uncomfortable and mildly painful on her. if you are in the recommended range (my eye doctor said within +/- 0.2 is potentially
okay--NOT definitely, just potentially) and decide to order a pair, i strongly recommend bringing the circle lenses in to the eye doctor if possible, so you can put them in and have them checked by a professional to make sure they fit safely. i do this with every pair i buy and it is
somewhat of a hassle, but i think the safety of my eyes is worth the time and money i spend at the eye doctor's. i've said this on a bunch of threads about lenses but i think it's a really helpful way to go about buying and wearing colored contacts/circle lenses for cosplay in the safest way possible.
i love colored lenses so i hope you find what you need and have a ton of fun with it!
