I’m firmly in the camp of fashion accessory. As I’ve stated in another related post, my son is a hearing aid user and soon to be cochlear implant user. When he first got hearing aids (age 3) we picked blue with red and called them Spiderman hearing aids. His eyes lit up in excitement.
Now, 3 years later, the prospect of wearing a much larger/bulkier device of a cochlear implant, he was concerned about it. That is, until, we discovered that we could do Orange, white, and grey, and make a BB-8 sticker for the head piece. Now he’s counting the days down until he gets it.
There’s a place for fashion accessory medical devices. Just look at prosthetics that are dye-sub printed with american flags, and the like. While there will be many ashamed of their handicap, many others prefer to break stigma by showing off what they have. My son may not always feel this way, but for now he’s proud of his devices, and will talk to anyone who asks about them.
