Hearing aid having two hearing apparatuses with optical signal transmission therebetween

A hearing aid comprising:

• first and second hearing apparatuses each containing hearing-improving circuitry, and each having an acoustic output port;
• an eyeglasses frame having two side bows joined by respective hinges to a center frame part, said first and second hearing apparatuses being respectively disposed at said side bows at opposite sides of head of a hearing-impaired person, with said output ports being adapted to be conducted into respective ear canals of said hearing-impaired person;
• said first hearing apparatus including an optical emitter for emitting optical signals and said second hearing apparatus including an optical receiver for receiving said optical signals;
• and
• an optical waveguide contained in said eyeglasses frame and extending along said side bows and said center frame part, between said first and second hearing apparatuses so that said optical receiver of said second hearing apparatus receives said optical signals emitted by said optical signal emitter of said first hearing apparatus via said optical waveguide.
