Anna University’s device engineers change in a hamlet

A fashion industry is built around the retina. In squares, rectangles, pentagonals and so on. Just inches away, the ear languishes in relative obscurity. Hearing aids only rarely become faddish. On closer scrutiny, this argument is specious. In any given population, those requiring a hearing aid would be outnumbered googolplex times by those in need of spectacles. The disparity is unmistakable when the scene shifts to underprivileged communities. Pardon the pun: Eye camps come out of ears. However, in these communities, many may be living with degrees of hearing loss when they do not have to.
