| Cameras have changed a lot in the last hundred years. Most cameras made today are digital and can easily fit in your hand. Mobile phones often double as cameras. The quality of these types of cameras has improved significantly too. We are even beginning to see cameras installed in eyewear. Researchers have built cameras so small, they can fit on the frame of a person’s glasses. These cameras can even record video. It’s like something out of a spy novel, except it’s now a reality. A consumer can actually buy a pair of glasses such as these. Even more remarkable is the idea of placing a camera in a contact lens. It has been done, although the technology is in its early stages. The makers hope it can help blind people to detect things around them. There are no plans to turn it into a consumer product, at least not yet. |
