More than 37 million Americans over the age of 18 have trouble hearing. And men are twice as likely as women to experience hearing loss. Not only can it impact your ability to enjoy life, but it also puts you at an increased risk of cognitive decline. In fact, there’s a five times increased risk of developing Alzheimer’s disease when you are hard of hearing. That’s why it’s imperative to get hearing aids if you’re having trouble. But only one in five people who need them use them. Now, a new type of hearing aid is revolutionizing the market—think of it as a contact lens for your ear.

Earlens can help patients whose hearing loss ranging from mild to severe. Patients are able to swim and do anything they would normally do with the Earlens. The only limitation is that if you need an MRI, the doctor will have to remove it. But replacing it takes a matter of minutes. The total cost of Earlens is $12,000.
