The idea: a condom that detects STIs and then glows. The designers explained that S.T. Eye would have a variety of colors coinciding with each infection it comes into contact with. For example, if someone has chlamydia it would glow green, yellow for herpes, purple indicating human papillomavirus (HPV), and blue representing syphilis.

The condom would contain a layer of molecules, which would bond to bacteria and viruses that compose common STIs. This in turn would cause a chemical reaction, producing a luminous glow in dim lighting — kind of like a glowstick.

‘We wanted to create something that makes detecting harmful STIs safer than ever before, so that people can take immediate action in the privacy of their own homes without the invasive procedures at the doctors,” Daanyaal Ali explained to the UK’s Daily Mail.

Although the S.T. Eye are strictly conceptual at this point, we’re eager to see how quickly it bursts from a glowing idea to a beaming reality. Until then, make sure you’re getting tested every six months (depending on how sexually active you are) and use protection. Have trouble fitting in a doctor’s appointment?
