EarLens Corporation is a medical device company that develops and manufactures hearing aids. The company was founded in 2005 by Rodney Perkins and is based in Menlo Park, California. EarLens's hearing aids use a laser diode to vibrate a lens that directly stimulates the eardrum, providing a more natural hearing experience. The company's products are sold through a network of audiologists and hearing aid dispensers. EarLens has raised over $200 million in funding to date.
