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.
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.
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.
Hey guys! So I may be new to cosplay, but I’ve been dabbling in circle lenses since my high school days and I thought it wouldn’t hurt to share this easy method of opening the lens bottle!
Over the years I found this method to work well in removing the metal seal on the bottle safely, and also saves your nails from breaking! I’ve admittedly broken way too many before I started opening them this way, haha!
Look for an embedded mark on the silver metal part underneath the upper white cap. This mark indicates where you should begin pulling off the white cap. Remove the white cap.
Following step 1, continue to pull the lid away in the direction opposite of where the mark is, until the silver part on the reverse side of the cap is peeled all the way down.
Use something thin and rigid, such as a nail clipper(pictured above) or tweezers. Wedge the object between the bottle and the metal part, and use the object to force the metal part away from the bottle.
Continue the action from step 3 all the way around the bottle.
Voilà! Now the seal is removed.
Now invert your lens bottle upside down with a shake to dislodge the lens from the bottom, remove lid partially so that there is enough room for the solution to come out but not enough for the lens to fall out!
If the lens is stuck at the bottom of the bottle after this step, pour some contact solution to dislodge the lens from the bottle and try again OR you may gently use a lens tweezer to get the lens out of the bottle.
Hold and rinse your lens with a multi-purpose disinfecting solution for contact lenses, such as Opti-Free(pictured above) OR a fresh saline solution*. Then, soak your lens in the solution for at LEAST 6 hours prior to wear.
This is a *very* important step, as the solution that comes inside the lens bottle is a saline solution intended for storage, and wearing your contacts straight from this solution may cause burning, irritation, and/or damage to your eyes.
Wear your circle lens, and look fabulous while doing it!
Feel free to let me know if there’s anything I should correct for clarity, and if you have any questions, fire away!
Also, stay tuned for another circle lens related post coming your way! I’m sure you guys know the basics, but I hope you guys will check that out ‘cause the way I see it, more knowledge is never a bad thing! :)
Pinky Paradise is an online store that sells a large variety of lenses for cosplay or daily wear and even offers prescription on many lenses! Currently they’re having a 50% off yearly lenses until October 15th. If you order now via express shipping, you will receive your lenses by Halloween!
