NO NO NO NO PLEASE DON'T EVER RECOMMEND PINKY PARADISE. Just look up Jessica Lynn and her 90% corneal abrasion caused by Pinky Paradise contact lenses.
Here is the deal: ANY contact lens you buy that is not given to you by your eye doctor or does not contact your eyedoctor to validate your prescription is generally not considered FDA approved in the US and can be unsafe for your eyes. ANY time you do not properly inspect, care for, insert or wear your lenses you have the risk of damaging your eyes. From my understanding, no circle lens is considered approved for the united states and are considered illegal because of that. Corneal abrasions are commonly caused by wearing contacts.
Edit: Pinky sells brands of contact lenses, they don’t produce them. Even though they sold the lenses to Jessica I think it’s important to note that the BRAND was Vassen and that the brand is available through other sellers as well.
I suggest all cosplayers do their research on lenses before wearing them so they know what the risks are. Go to an eye doctor for your first pair, learn proper care/storage/wear/removal, understand why they aren’t FDA approved and check that if it’s a korean brand (EOS, GEO etc) are at least KFDA (Korean FDA) approved.
You’re sticking plastic in your eyes, be as safe as possible about it.
The reasons I will suggest Pinky are: It’s very commonly used with few horror stories (that I have seen), Encourages you to talk with your optician for diameter / base sizing (FAQ section), Gives instructions for wear and removal, They support checking GEO codes for fake lenses, Has a New User guide which also encourages you to contact your optician. States that all their lenses are KFDA approved - this is not USA FDA approved.
marshmallowfeferi said: Geo Medical is actually US FDA approved now so if you want to be save that’s the best bet
Just double checked this and they are! [source] [source] and approved by Health Canada ;)
By now, we’re all familiar with the idea of wearable health trackers. But we’re used to seeing them on our wrists. If Google gets its way, the next batch of wearables may be worn in your eyes.
The company’s experimental wing, Google[x], announced on Thursday its plan to test a prototype of a smart contact lens that would monitor the sugar levels of diabetes patients, possibly alerting them when glucose levels become dangerously high or low.
A polymer film coating with the ability to turn contact lenses into computer screens is set to transform the wearable visual aids into the next generation of consumer electronics.
Scientists from the University of South Australia’s Future Industries Institute have successfully completed “proof of concept” research on a polymer film coating that conducts electricity on a contact lens, with the potential to build miniature electrical circuits that are safe to be worn by a person.
UniSA researcher from the FII, Associate Professor Drew Evans said the technology was a “game changer” and could provide one of the safest methods to bring people and their smart devices closer together.

Prompted by the rapidly developing field of wearable electronics, research into biocompatible substrates and coatings is intensifying. Acrylate-based hydrogel polymers have gained widespread use as biocompatible articles in applications such as contact and intraocular lenses. Surface treatments and/or coatings present one strategy to further enhance the performance of these hydrogels or even realize novel functionality. In this study, the conductive polymer poly(3,4-ethylenedioxythiophene) (PEDOT) is deposited from the vapor phase onto hydrated hydrogel substrates and blended with biocompatibilizing coconstituents incorporating polyethylene glycol (PEG) and polydimethyl siloxane (PDMS) moieties. Plasma pretreatment of the dehydrated hydrogel substrate modifies its surface topography and chemical composition to facilitate the attachment of conductive PEDOT-based surface layers. Manipulating the vapor phase polymerization process and constituent composition, the PEDOT-based coating is engineered to be both hydrophilic (i.e. to promote biocompatibility) and highly conductive. The fabrication of this conductively coated hydrogel has implications for the future of wearable electronic devices.
Not sure which way your contacts should go? Do the taco test! Place contact on a crease of your finger, then curl your finger to gently bend the contact. If it folds like a taco then you’re good! If it falls flat, you’ve got it inside out.
Brian Otis gingerly holds what looks like a typical contact lens on his index finger. Look closer. Sandwiched in this lens are two twinkling glitter-specks loaded with tens of thousands of miniaturized transistors. It’s ringed with a hair-thin antenna. Together these remarkable miniature electronics can monitor glucose levels in tears of diabetics and then wirelessly transmit them to a handheld device.
“It doesn’t look like much, but it was a crazy amount of work to get everything so very small,” he says.
