THE CHALLENGE
Medical Non-Compliance
We were tasked to breakdown a problem and to find a solution. What we found, among other data, was that approximately 1/3rd of users don’t wash their hands before inserting their contact lenses. The consequences of this can be hugely impactful and so we decided to do something about it.
​
The flow chart shows our original thought process on the entire contact lense routine and identifies where users may not follow medical guidance.
OUR MISSION
Develop a storage system to improve the compliance of an athlete’s contact lens routine whilst away at fixtures. In doing so, reducing the introduction of bacteria to the eye to prevent risks of microbial infection.
OUR SOLUTION
We decided that the best way to ensure compliance was not to simply encourage or enforce a user to wash their hands, but to skip that step in the lens routine entirely! This tied in with our focus on athletes who may not even have the facilities to do so whilst pitchside.
​
Our design below is an applicator case, and as explored further on, contains two sliding trays that use a unique silicone sheet design that separates the user's finger from the lens. No direct contact. Skip the step!
CONCEPT CREATION
Here we explore our initial sketches as our focus & ideas developed and matured. Using our initial process flow chart we were able to identify different steps in the routine to work on.
We also explored ideas looking into different methods of portability with designs incorporating phone cases, wallets, and key rings.
We then expanded, and looked into our decision to skip the process of any direct contact with the lenses themselves. Testing some products in the market as detailed in analysis within our report, we developed a few solutions incorporating an applicator within the case itself.
SECOND SKIN
Development of silicone sheet
After testing existing products that our concepts above were based on, we discovered that the current applicators on the market were very fiddly to use and still required direct contact with the lenses themselves.
Inspiration then whilst watching a rugby match where a player had a lens adjusted by a glove wearing medic. We needed to design a second skin, an inbuilt glove. Why couldn't we also make it an inherent feature of the design itself?
Taking this inspiration, we moved forward with developing the second skin idea. Using a silicone sheet to act as a second skin. Initial testing quickly showed that a pinch motion is required and so similar to the diagram, we incorporated a dome within the sheet design.
​
The sheet would open/close the lens shaped dome in a pinching motion when pressure is applied to the top of the dome.
Choosing to develop the tray design shown above, we varied shape, number and position for the casing, trays and gear mechanism. Work was done to look at button designs to hold the lens in place within the tray when not in use.

VISUALISATION
Our final design came together. We have used two trays with a yin-and-yang inspired pattern that allows them to stack with a thinner profile. Gears have been placed at both sides and colour coded to differentiate right and left sides. The trays use a silicone 'second skin' to hold the lenses in place and to allow placement and the flexibility for adjustment, of the lens within the eye without any direct contact. A range of aesthetic finishes are as below, with animations included to demonstrate the moving parts.

A premium add-on of our product could be to allow full customisation using anodized aluminium bodies and foil wrap decals. Below are a few Avenger themed examples!

THE CUSTOMER PROCESS
To maintain medical compliance, the user does not ever come into direct contact with the contact lenses. Working alongside current business models were contact lenses are provided on prescription and refreshed on a monthly basis, our design allows each contact lens to be sealed under laboratory conditions by trained staff before being sent to the user. By keeping the design thin, each delivery will fit through the post box, ensuring delivery 24/7.
